sphyraena sphyraena , the european barracuda or mediterranean barracuda , is a ray-finned predatory fish of the mediterranean basin and the warmer waters of the atlantic ocean .

sphyraena sphyraena

jennifer hammock split the classifications by inventaire national du patrimoine naturel from sphyraena sphyraena ( linnaeus , 1758 ) to their own page .
there are no species - specific conservation measures in place for sphyraena sphyraena , however , the range for this species overlaps with a number of marine protected areas .
sphyraena sphyraena is normally a pelagic species found high in the water column , but smaller fish are often found near the bottom of the water column . the main food is other fish but sometimes includes cephalopods and crustaceans . they are a social species and large groups of sphyraena sphyraena could number between ten and a few hundred .
the genus sphyraena belongs to the family sphyraenidae , the order perciformes , class actinopterygii , phylum chordata and kingdom animalia . the genus sphyraena is the only genus in the family sphyraenidae .
justification : sphyraena sphyraena is widespread and relatively common throughout the mediterranean . it is a commercial species but there are no serious threats at present . therefore , it is listed as least concern .

its habits are probably similar to those of the phylogenetically closely related sphyraena sphyraena ( ref . 6949 ) . feeds on cephalopods , crustaceans and fishes . caught in trammel nets and beach seines ( ref . 11101 ) .
eastern central atlantic : cape verde and the canary islands . also reported from lebanon in the eastern mediterranean . its exact distribution and abundance are unknown because most published records do not separate it from sphyraena sphyraena . also in azores islands ( ref . 44330 ) .
indo - west pacific : red sea and east africa to new caledonia and vanuatu , north to southern japan . reported from fiji and tuvalu ( ref . 12596 ) . the exact range is uncertain because of confusion of this species with sphyraena jello and sphyraena qenie ( ref . 9768 ) .

the sea around fuerteventura is much cooler than many people expect due to the cold canary current , which brings cool water down from northern europe . it is this temperate water that gives the island its world famous climate , for without it , temperatures would be much higher and the archipelago much dryer than it is .
whales , dolphins and turtles are frequent visitors and big game fishermen have set world records off its coasts . close to the shore , colourful shoals of parrotfish graze on rocks that harbour moray eels and brightly coloured wrasse and damsel fish . seahorses live in the seagrass and huge rays patrol the bottom . octopus and cuttlefish are abundant , along with an almost infinite variety of smaller organisms , such as brightly coloured sea urchins , crabs and sponges .
spaisoma ( euscarus ) cretense this is the single most famous fish species around fuerteventura . a sexually dimorphic species , the female being brightly decorated with red , yellow and blue and the male a drab greyish brown . while juveniles are often seen alone , larger viejas group together , sometimes in schools of several hundred , to feed over rocky bottoms down to 50m . feeds on invertebrates and especially crabs , relying on its prominent beak - like teeth .
the most characteristic canarian fish much sought after by divers and fishermen alike the vieja remains an important commercial species despite heavy overfishing . a reduction in the use of nasa fish traps has seen an increase in the population around gran canaria . traditionally fished for from small craft using salted crabs on large hooks and a rod tipped with a stingray tail .
liza aurata the most common of several mullet species around the island , the golden mullet is often seen in harbours and close to the shore . large shoals are often encountered and large specimens are found grazing in very shallow water . an algae and debris feeder , it can be attracted with bread and , while not often consumed in the canaries , is a challenging fish to catch .
abudefduf luridus small but spectacular , the black damsel fish is found almost everywhere but especially over rocky and weedy bottoms in shallow water . its bright blue colour and trusting nature make it a diving favourite . it can sometimes be tempted to feed from the hand and is often seen along harbour walls and in rockpools . males develop orange patches during the breeding season .
thalassoma pavo one of the commonest and most beautiful fish in canarian waters the peacock wrasse is often found in mixed shoals along with the black damsel fish and band - tail chromis . found everywhere except over pure sand bottoms from the inter - tidal zone down to depths of 200m . males are larger with more distinctive coloration and , like many wrasse , this species can change sex .
at night , giant manta rays sometimes come into harbours to feed around lights . a torch shone down the walls will reveal goldfish - like cardinal fish and the larger red and white glasseyes , which have large eyes that glow in torchlight . black and silver bream or ‘sargos’ are much more active at night and large , mixed groups can often be located with a torch .
heteropriacanthus cruentatus common but nocturnal , the glasseye is found hiding in caves during the day and allows divers to approach closely . common in the cracks and crevices of harbour walls and manmade structures . like the vieja , the glasseye is susceptible to crustacean parasites . an attractive species with limited interest as a sport fish .
polyprion americanus a deep sea species found from gibraltar to southern angola the wreckfish is an important commercial and food fish in the canary islands . found between 200m and 800m most wreckfish caught around the canaries are much smaller than the maximum .
pseudolepidaplois scrofa found on rocky and mixed bottoms down to 150m the hogfish is an important species for traditional fishermen , even though it is listed as threatened . an attractive species , it is rarely seen by snorkelers as it prefers deeper waters . often seen in the mixed catch of small fishing vessels arriving back in port on fuerteventura .
a trip on an inter - island ferry or a water - taxi can often be a rewarding experience for those looking for wildlife . a variety of shearwaters and petrels will be seen , flying close to the water’s surface . some , such as the white - faced storm petrel are very rare and breed only on one or two of the canary islands . graceful terns are often seen around the coast , and a group of them plunging into the sea to catch small fish is a beautiful sight .
dolphins and porpoises are common in our waters and often ride the bow waves of ferries . among the larger cetaceans , pilot whales are common and sperm and killer whales are often seen off the fuerteventura coast along with risso’s dolphin . several species of turtle visit and are occasionally washed up after becoming trapped in fishing nets or fouled with oil .
other creatures that are sighted from boats include blue and hammerhead sharks , portuguese man of war jellyfish , flying fish and manta rays .
belone belone gracilis small shoals of this curious fish appear close to the shore around fuerteventura in the summer months . rarely seen more than a few centimetres from the surface the greenbone garfish is often missed by divers and snorkelers . good eating despite its slender build and green bones .
katsuwonus pelamis a small , schooling tunnid that runs in canary waters through the summer and autumn . an important commercial and sporting species the skipjack is traditionally caught with rod and line from small offshore craft . a voracious fish eater that is particularly fond of bogues .
thunnus alalunga one of several large pelagic and epipelagic tunnid species common in canarian waters at certain times of year along with the yellowfin , big - eye and bluefin tuna . all are important commercial and sport fish and can be caught from chartered sport fishing craft in the south of gran canaria .
pseudocaranx dentex an epibenthic to pelagic species found down to depths of 100m , the guelly jack is a powerful predatory fish at the top of the coastal food chain . once a common species , it has been overfished to the point where it is rarely seen . juveniles are sometimes still found around mooring buoys and sometimes “adopt” divers and snorkelers , as well as large fish such as saddled bream
scomber japonicus one of two mackerel species present in canarian waters at certain times of year along with the frigate tuna . both are fished commercially and are good fishing from small craft . large schools of small chub mackerel are sometimes found close to the shore often in the company of bogues .
makaira nigricans an oceanic species reaching 650kg that is quite common around the canary islands and an important sport fish . several blue marlin world records have been broken around the archipelago and the waters of the canaries are famous for their large specimens . chartered fishing boats operating from the harbours of the island seek out this species . the physically similar swordfish is also occasionally caught although it prefers warmer waters .
exocetus volitans a curious species found in small groups close to the surface . capable of leaping clear of the water and “flying” up to 100m using its elongated pectoral fins . a plankton feeder that is hunted by tuna , the flying fish is often seen flying away from boats and ferries around fuerteventura .
a wide selection of shells and other objects can be collected from fuerteventura’s beaches , especially after storms . among the most common are cuttlefish bones , well known due to their use as a source of calcium for canaries . they often wash up on beaches and are more often seen that the living creature . delicate spiral ramshorns also come from a seldom seen squid and are very common along the strand line . also common are the very delicate lilac shells of the janthinidae , which live under a raft of bubbles , only washing up on the shore after stormy weather .
stranded jellyfish also wash up , sometimes in large numbers , and should not be handled as they are still capable of stinging . common shells to be found empty along the coastline of the canaries include sea urchins carapaces without the spines . these can be green , purple or brown and are as beautiful as they are fragile .
venus ear shells are easily recognisable , with one side covered in mother of pearl . the living venus ear lives stuck under rocks , emerging after dark to graze on algae . limpets , winkles and dog whelks are common all around the canaries , while cowries , mussels , cockles and scallops also turn up . goose barnacles can be found attached to almost any piece of floating debris that has been in the water for a decent length of time .
rockpools are perhaps the best place to see a wide selection of sealife without the need to get too wet . low tide leaves large areas of rock exposed around the coast , trapping animals that cannot normally be seen without a mask and snorkel . in general , the less time rocks are exposed to the air , the more life is found on and among them . especially low spring and neap tides expose areas that are usually underwater and these can yield very rich pickings for the naturalist . some caution is needed when exploring rockpools , as the tide comes in fast and exposed rocks can be very slippery .
a few of the animals that are found can also cause damage . sea urchin spines snap off under the skin and cause painful injuries , while the red and white bristleworms to be found under rocks are best avoided , as their bristles irritate the skin . brown sea cucumbers exude a white fluid when handled , which is very hard t o remove from skin or clothing .
small scorpionfish , often trapped in rockpools , have poisonous spines and large crabs can deliver nasty nips with their powerful claws . it is always best merely to observe any creatures found , as much for the observer’s benefit as their own . do not forget to replace any rocks that you turn over and make sure any shells you take home do not already have a rightful owner , as hermit crabs are plentiful around fuerteventura .
even the smallest and shallowest rockpool is likely to have fish living in it . gobies and blennies are small specialists in this particular habitat and , with patience , can be tempted to take bread or squid from the hand . baby mullet and sucker fish are also often found in the smallest pool . in deeper pools closer to the low tide mark , the number of fish species to be found increases . fulas and pejeverdes are common , while small sargos , mullet , grouper , wrasse and scorpionfish are also evident . in deep pools with caves , moray eels lurk , along with larger grouper and a wide variety of other fish .
other organisms to be found in rockpools include small , transparent shrimps which will often come and nibble on a foot left in the water , a variety of crabs , including the hairy ‘jaca’ , which is very tasty and much sought after . grey sea hares , with black circular marks , and sea cucumbers are often found in cracks and caves , along with a wide variety of urchins , sponges and anemones . a careful search among the seaweed will often reveal small but brightly coloured sea slugs and starfish .
bright red sally lightfoot crabs are easily spotted on exposed rocks , but are very shy . they are caught in the canaries with bait wrapped in a ball of rough thread , which tangles up their claws . at night , tubeworms extend their delicate fans and pluck small morsels from the water and crabs come out to feed , safe from the sleeping seabirds . perhaps the best way to find rockpool inhabitants is to turn over rocks and stones . this should be done very sparingly and the rocks carefully replaced as many of the creatures found under them are killed by sunlight . many rocks also have sea urchins underneath them .
look out for brightly coloured orange and yellow sponges , shy peacrabs and the highly mobile bristlestars , which will wriggle off as soon as they detect light .
while a wide selection of marine life can be seen from above the surface , taking the plunge and joining it underwater opens up an entirely new world . snorkel kits are widely available in most shopping centres and are very reasonably priced although , for the sake of comfort , it is often best to spend a little more than the minimum . there are dive centres in most resorts and they cater for a wide range of abilities , from absolute novices to experienced divers . in some areas , there are commercial glass - bottomed boats and even submarines , which allow you to experience the underwater world without getting wet and with the added bonus of an experienced guide .
diplodus sargus cadenati the most common of a number of sea breams around fuerteventura , the white sea bream is present almost everywhere . it forms small shoals of different sized individuals which will often follow divers . once heavily fished , especially by speargunners , it remains an important commercial and sport fish , best sought after at night . the similar annular sea bream is smaller and closely linked to sandy bottoms and seagrass beds .
diplodus cervinus cervinus the largest commonly encountered canarian sea bream , the zebra sea bream is a spectacular if retiring species , especially when adult . small shoals and pairs are often found over rocky and mixed bottoms down to 100m . smaller specimens are more brightly coloured and are found closer to the shore . a good , if hard to catch sport fish that has suffered at the hands of speargunners .
diplodus vulgaris a common and easily recognised species , the 2 - banded sea bream is found over all bottoms . usually seen alone or in pairs , the juveniles group together in mixed shoals along with other sea breams . rarely larger than 20cm in fuerteventuran waters , it is of limited commercial and sport fishing interest .
sarpa salpa one of the most frequently encountered fish in fuerteventuran waters , the salema forms large uniform schools close to the shore . in bright light , they appear blue with fine yellow stripes . a grazing species its abundance may be due to the unpleasant muddy flavour of its flesh . a good sport fish that is attracted to bread and is not afraid of divers bearing food .
boops boops a very common species that has benefited from the overfishing of its predators . bogue populations can assumes almost plague proportions in some areas . rarely eaten as it is traditionally considered a dirty fish that feeds on the corpses of fishermen . found in open water down to 250m . an important bait fish for tunny fishing .
gobius paganellus one of several goby species common in shallow water and the intertidal zone . best observed at low tide when they hunt fearlessly in rockpools gobies will happily eat almost anything offered to them . of no interest to fishermen due to their small size , gobies are occasionally caught accidentally .
coryphoblennius galerita several similar blenny species are found in shallow waters and rockpools around fueeteventura . more sinuous than the gobies , blennies are also more wary . extremely common in some areas blennies are of no interest to fishermen due to their small size .
trypterygion tripteronotus a tiny but spectacular species this blenny is found in pairs in shallow water over rocky bottoms . the brightly coloured male is instantly recognisable due to its black head and orange body . pugnacious despite its size it sometimes attacks divers’ fingers , especially during the breeding season .
ophioblennius atlanticus atlanticus the largest of the gobies and blennies around the canaries the rubber eye is recognised by its cream head and almost black body . populations can be quite dense on exposed rocky bottoms covered with diadema sea urchins and on harbour walls . aggressive with its own kind , the rubber eye is unafraid of divers . it is very seldom caught , even by accident , by fishermen .
even areas of completely bare sand support specialist animals . small flatfish rise from the bottom if the swimmer gets too close and are well worth observing for their curious form of locomotion . they are often seen in pairs and are surprisingly curious and unafraid of divers . they have a habit of settling on the bottom and disappearing in a puff of sand , leaving only their protruding eyes above the sand .
xyrichthys novacula the cleaver wrasse is an attractive species linked to sandy bottoms and sea grass beds , where it can be quite frequent . if disturbed it has the ability to burrow into the sand faster than the eye can follow . a favourite food of dolphins which have been observed burrowing into the sand to capture them . a good food fish with firm , white flesh .
lithognathus mormyrus found strictly close to sandy bottoms , the herrera can form large schools of similar sized individuals . fond of bare sand bottoms exposed to breaking waves it is recognised by its elongated body , numerous pale bands and large white lips . large specimens are often encountered close to the shore . the herrera is an excellent sport and eating fish aught with rod and line from the shore or from small craft .
synodus saurus found on rocky and sandy bottoms down to 100m the lizard fish is a voracious predator that will consume anything that fits into its considerable mouth . cannibalism is not uncommon and they have been known to swallow small fish hooked by fishermen , releasing them when pulled out of the water . easily recognised due to their shape , lizard fish are most often observed lying motionless and half buried on the bottom . a similar species is found in deeper waters .
trachinus draco the fish species most likely to injure swimmers in the canary islands the greater weever lives on sandy bottoms down to 50m . small specimens are found buried in the sand in shallow water and have venomous dorsal spines that deliver a powerful sting to anyone unwary enough to tread on them . an attractive species with blue markings and a black dorsal fin that is understandably unafraid of divers .
bothus podas maderensis common on sandy bottoms down to 90m , this is a subspecies endemic to the canaries and madeira . small specimens are often seen in shallow water close to beaches . instantly recognisable , the flounder is unafraid of divers and a charismatic fish . often caught from small craft by rod and line fishermen fishing on the bottom large examples make for good eating . the flounder’s local name of “tapaculo” translates as “buttock cover” .
among the most remarkable seagrass specialist is the seahorse , very common in some areas but hard to spot and very shy . patches of floating seagrass uprooted during storms often harbour its relative the pipefish , just as shy and very well camouflaged . another notable inhabitant in the culebre , a type of eel that looks exactly like a sea snake . it often shelters in sunken car tyres and is a harmless , retiring fish . another eel lives in colonies of several hundred and spends its life half buried in the sand . if a diver approaches too closely , the eels will disappear , emerging when the coast is clear .
stephanolepsis hispidus a common and trusting fish the yellow trigger fish is unmistakeable when encountered . while seemingly slow moving it is capable of speed if threatened . a popular food fish that must have its leathery skin removed before cooking . difficult to catch with rod and line due to its powerful teeth and patient nature it is a famous baitstealer .
mullus surmuletus closely linked to sandy bottoms and seagrass beds , the red mullet is often found digging in the sand for invertebrates . indifferent to divers it is recognised by its prominent white barbells and elongated body . an important food fish wherever it is found the red mullet is rarely caught by rod and line fishermen in the canaries .
hippocampus hippocampus a small and rarely seen species , the seahorse is found in seagrass beds and on weedy bottoms between 8cm and 12cm . considered rare , it is so seldom observed due to its excellent camouflage and slow movements that its exact status is unknown . the closely related pipefish also occurs around fuerteventura and can be observed around floating mats of seagrass .
caves are also the best place to see sea urchins , in a variety of colours , sea anemones , sea cucumbers , sea hares and sponges . long - spined black sea urchins are common and have assumed plague proportions in some areas , grazing so intensively that algae has no chance to grow . areas of white rock covered in urchins are called urchin bights and tend to support fewer fish than areas without urchins . part of the problem is the overfishing of predators such as triggerfish and triton shells , which keep urchin numbers under control . some divers crush these urchins whenever they can in a bid to control them but this is not advisable , as the spines are poisonous . the urchin’s long spines also provide a home for a variety of juvenile animals and small creatures , such as shrimps and spider crabs .
epinephelus marginatus one of the stars of the diving world in the canary islands , the dusky grouper is easily tamed and will feed from divers’ hands . groups of different sized individuals are often found sharing the same cave . an important commercial fish that has is now listed as threatened as it is an easy and attractive target for spear gun fishermen and has been severely overfished .
mycteroperca fusca a benthic species that found down to 150m and quite common in places . juveniles are often seen by divers and snorkelers and a spectacular , bright yellow morph is sometimes found . threatened by over fishing and indiscriminate spear gun fishing , the comb grouper is an important sporting and commercial species .
chromis limbatus similar to the previous species but usually found at greater depths the band - tail chromis can form large schools in open water above rocky bottoms . males develop purple backs during the breeding season . a common species seen on most dives , often in large numbers . one of the few species to thrive over rocks infested with diadema sea urchins .
pomadasys incisus a common species known locally as the snorer due to the audible noises it makes when caught . large banks of bastard grunts are often found close to the shore and are unafraid of divers . a good sport and eating fish that is abundant partly because it rarely enters fish traps . the related striped grunt is found in small colonies between 20m and 150m . it is used by fishermen as a marker species as it lives closely linked to underwater reefs .
canthigaster rostrata a common shallow water species that is not afraid of divers , the sharpnose pufferfish can inflate its body with water if threatened . considered poisonous by some , it is sometimes eaten after careful cleaning . a major baitstealer and linebreaker due to its powerful front teeth , it is considered a pest by fishermen .
scorpaena scrofa one of two similar scorpionfish fund in shallow water over rocky and weedy bottoms but also down to 200m . both rely on their excellent camouflage for defence and hunting and have poisonous spines . scorpion fish are often caught by rod and line fishermen and are good eating , especially in fish soups .
fish farming is becoming an important industry around the archipelago and will eventually be widespread enough to cope with the demand for fresh fish . it has had unforeseen consequences , as several of the species farmed are not naturally found around the islands and have escaped . the impact of these alien species is not yet understood and could seriously affect populations of native species .
overfishing is , however , still a threat to some species and those that feed off them . whitebait netting has been banned for several years after these fish were almost driven to extinction and the jurel , a kind of jack , has almost completely disappeared from some islands due to its affinity for fish traps .
rubbish generated by the 10m tourists passing through the islands every year also has a detrimental effect on sealife . turtles mistake plastic bags for jellyfish and swallow them and along with birds , get tangled in fishing line and plastic rings from drinks cans . the deforestation of mountain areas and continued hotel development mean rainwater erodes the soil and washes it into the sea , where it clouds the water and prevents light - dependent organisms from growing , as well as reducing visibility for the diver .

the steppe eagle ( aquila nipalensis ) is a bird of prey .

it was once considered to be closely related to the non-migratory tawny eagle ( aquila rapax ) and the two forms have previously been treated as conspecific .

they were split based on pronounced differences in morphology and anatomy ; two molecular studies , each based on a very small number of genes , indicate that the species are distinct but disagree over how closely related they are .

the habitat for the steppe eagle must be protected . agricultural practices should respect the habitat and the conservation of steppe birds like the steppe eagle .

juvenile eagle and immature often show broad white band along the greater coverts on the underwing . plumage is paler . the young steppe eagle reaches the adult plumage at 4 - 5 years .
the steppe eagle is a quiet bird , only vocalising during the breeding season . their call sounds somewhat like a barking crow .
beside that , the large scale destruction of steppe habitat and conversion the agricultural land ( and the following reduction of prey like susliks ) is the major reason for the decline of the steppe eagle .

steppe eagle arrives in march at breeding areas . both mates often arrive together . in this species , breeding season is strongly dependent on preys’ availability .
during a dive steppe eagles can reach a speed of 300 kilometers per hour .
story by andrea egan , vadim kirilyuk and undp russia / photos : undp / gef steppe project team and natalia sudets for undp steppe project and undp russia .
similar species within the steppe eagle’s nesting sites , similar breeds of eagles exist - the white - tailed eagle ( haliaeetus albicilla ) , golden eagle ( aquila chrysaetos ) , imperial eagle ( a . heliaca ) and greater spotted eagle ( a . nipalensis ) . all the above - listed species , as well as the lesser spotted eagle ( a . pomarina ) , which is most similar to the steppe eagle , migrate to the same areas , which makes identification of species difficult . when trying to identify eagles , attention must be turned to the colour of the underside of the wing . the young steppe eagle can be distinguished from the other eagles by the ‘juvenile band’ , formed cleanly by white lower coverts . with age the band turns black and by the age of 5 it will have almost completely disappeared . at this age the key indicators identifying the steppe eagle will be its wing and tail proportions , wing position in flight , and the length of the foot relative to the tail .
protection / threats / status : steppe eagle is vulnerable to persecution , changes or destruction of their habitat for agriculture , and collision with power lines . this species may be common in suitable habitat , and it is one of the most common eagles in the world . steppe eagle is not threatened at this moment .
as the name already says , the steppe eagle is a bird of open habitat like steppes , desert , semi - desert , grasslands and even agricultural areas .

[ birdlife international 2004 ] birdlife international . 2004 . birds in europe : population estimates , trends and conservation status . birdlife interntional . cambridge , uk . ( steppe eagle species account available at :
although generally considered common throughout its range , as a result of persecution , collision with power lines , and the conversion of steppe to agricultural land , the steppe eagle has disappeared from romania , moldova and ukraine ( 2 ) . nevertheless , it remains the most common eagle species of its size in the world ( 2 ) , and is therefore not considered to be threatened ( 1 ) .
a relatively large , handsome bird of prey , the steppe eagle closely resembles a number of related eagle species such as the tawny eagle , aquila rapax , that occur within its extensive range ( 2 ) . the plumage is mostly dark brown , with well - defined bars on the flight and tail feathers ( 2 ) ( 4 ) . the main distinguishing features are the reddish - brown patch on the nape of the neck , the oval nostrils , and the long , wide gape . there are two recognised subspecies of steppe eagle , aquila nipalensis nipalensis and aquila nipalensis orientalis , the latter being slightly smaller , with paler plumage . the juvenile steppe eagle resembles the adult but is paler brown , with a characteristic broad white band running along the underside of the wing ( 2 ) .
) . therefore , it is possible that minks may also prey on lesser spotted eagle eggs .
for many inhabitants of the steppes , the eagle is held with a reverence that borders religion .

. . . steppe eagles aquila nipalensis ( sharma et al . , 2014 ) suggesting the possibility that diclofenac is toxic to other accipitrid raptors , such as the threatened spanish imperial eagle . . . .
habitat in most parts of its breeding range , the steppe eagle is typically an inhabitant of the open steppes and semi - desert spaces . in contrast to other eagles , it has truly mastered overland habitats , and thus a wide range of landscapes . the habitats of the steppe eagle can be categorised into the following : 1 . low steppe hills 2 . valley - beam systems in steppe zones , including in agricultural landscapes . 3 . vast , flat territories of undisturbed dry desert steppes , semi - deserts , and northern argillaceous scree deserts . 4 . steep slopes and cliff plateaus of steppe and semi - desert zones . 5 . all types of open spaces in the hills , regardless of the high - altitude zone ( steppe valleys , forest steppes around their peripheries or mountain plains , upper boundaries of forests , alpine tundras ) .
behaviour : steppe eagle feeds almost exclusively on several races of susliks , and especially little suslik ( citellus pygmaeus ) , small rodent related to terrestrial squirrels . it also may take other small rodents and young terrestrial birds , and occasionally crickets and reptiles . steppe eagle hunts from a hide and often pursues the prey before to catch it . this eagle may hunt by walking , or while flying , by circling and diving . it also waits at burrow entrance for rodents . it captures the preys with the talons .
habitat : steppe eagle frequents grassy steppes and semi - desert . the subspecies “nipalensis” is found in mountainous areas during the breeding season , up to 2300 metres of elevation , whereas the race “orientalis” breeds in lowlands .
. . . other external stressors relevant to steppe eagle mortality have recently been demonstrated as a potential threat to the species . specifically , the veterinary drug diclofenac responsible for large - scale declines in gyps vultures in south asia has recently been implicated in the death of steppe eagles ( sharma et al . , 2014 ) . the findings suggest that , as facultative scavengers potentially present in areas where diclofenac may be used as a veterinary drug , 31 steppe eagle populations may be exposed to and consequently adversely affected by diclofenac residues in carcasses . . . .

voice : sounds by xeno - canto steppe eagle is usually silent outside breeding season , but when displaying , it utters crow - like barking . calls are often given during some behaviour such as displays , contact , alarm and threat .
flight : steppe eagle has long , broad wings , and flies with heavy , slow wing beats . when circling , the wings are held horizontally with slightly hanging hand . when soaring , wings are raised and bent at hand level .

( 2014 ) mentioned that the steppe eagle is a vulnerable to diclofenac which was inten - sively used in the species ' wintering range in pakistan and india ( birdlife international , 2016b ) . in iraq , little is known about poi - soning as a threat to birds of prey . . . .
go here fledglings of the steppe eagle can be distinguished easily from other eagles by its longer beak and the colour of the primaries developing from pins , tail feathers and remiges on the upper and undersides of the body . after the opening of the primaries , the juvenile can be easily distinguished from that of the golden eagle and the eastern imperial eagle : the upper coverts of the spine and shoulder are brown , and the remiges and tail feathers are ochre - coloured .
as its name suggests , the steppe eagle mainly inhabits vast , semi - arid areas of grassland , known as steppe , although it also frequently occurs in semi - desert . during the breeding season , aquila nipalensis orientalis can be found in lowlands and low hills , whereas aquila nipalensis nipalensis occupies mountainous areas up to elevations of 2 , 300 metres ( 2 ) .
saryarka - steppe and lakes of northern kazakhstan protects substantial , largely undisturbed areas of central asian steppe and lakes in the korgalzhyn and naurzum state nature reserves . the property’s wetland areas are of outstanding importance for migratory waterbirds , including substantial populations of globally threatened species , as they are key stopover points and crossroads on the central asian flyways . the property’s steppe areas provide a valuable refuge for over half the species of the region’s steppe flora , a number of threatened bird species and the critically endangered saiga antelope .
to find food the steppe eagle flies over its territory . when it discovers prey it rushes down and kills it on the ground with its powerful claws . prey comprises predominately small mammals , especially gophers , but also small birds , insects and reptiles . the also feed on fresh carrion or steal prey from other animals . the steppe eagle has a crop in the throat which allows it to store food before it is moved to the stomach or regurgitated in order to feed its offspring .
mitch is a steppe eagle that cannot fly . his brown wings , permanently injured , no longer soar through the air . still , mitch is about to head from afghanistan to new york , thanks to the help of a few caring soldiers .
thus , the imperial eagle project will provide the chance to learn more about the eastern imperial eagle and improve the conservation of this bird in azerbaijan with the involvement of the media , local community stakeholders , infrastructure companies and governmental authorities .
federal wildlife laws recognize the importance of accommodating tribal spiritual needs by allowing exceptions for the religious purposes of indian tribes . eagle feathers are made available to tribal members every year from the fish and wildlife service ' s national eagle repository .
the
steppe eagle
( aquila nipalensis ) ( kazakh : дала қыраны ) is a bird of prey . like all eagles , it belongs to the family accipitridae . cultural significance : the steppe eagle appears on the flag of kazakhstan , as the
national bird of kazakhstan
respectively . habitat and feeding : the steppe eagle breeds from romania east through the south russian and central asian steppes to mongolia . the european and central asian birds winter in africa , and the eastern birds in india . it lays 1–3 eggs in a stick nest in a tree . throughout its range it favours open dry habitats , such as desert , semi - desert , steppes , or savannah . it is found in south - eastern pakistan especially in karachi .

. . . it may also be that diclofenac affects other vulture species , such as bearded gypaetus barbatus , egyptian neophron perc - nopterus and cinereous vultures aegypius monachus , and facultative avian scavengers , such as the red kite , spanish imperial eagle , golden eagle aquila chrysaetos and black kite milvus migrans . circumstantial evidence suggests that the steppe eagle which is in the same family ( accipitridae ) as vultures , kites and other eagles , may be susceptible to diclofenac ( sharma et al . 2014 ) . . . .
researchers find dead steppe eagles with diclofenac residues in their tissues in rajasthan ; experts say it points to alarming trend for all indian raptors .
remarkable is the velocity that steppe eagles can achieve during their flight . they can reach up to 60 kilometer per hour and when they dive they fall with a speed up to 300 kilometer per hour . compared with other birds steppe eagles spend relatively much time on the ground .

the steppe eagle is a large and handsome bird of prey , belonging to the aquila , or eagle , family . as its name suggests you will find it living in steppe habitats , or dry grasslands , across eastern europe . you will also find them on the national flag of kazakhstan , pictured flying beneath the sun . they are fast for their size , reaching flying speeds of up to 37mph , and incredible speeds of up to 186mph when diving . when migrating for the winter they can fly an incredible 220 miles in a day .
we had suspected as much from observed declines in non - gyps vultures in asia , but this study confirms our worst fears . ” taking from empirical evidence , experts fear that just like the steppe eagles , other species of eagle may also be affected in the same way .

appearance the steppe eagle ( aquila nipalensis ) is a large eagle , with broad , long wings and a short rounded tail . adult birds are brown in colour . the undersides of the wings are either the same colour as the wing coverts and belly or darker , with visible barring . there is a white patch on the upper tail coverts . the nape has either a rusty - coloured or ochre patch , which differs considerably in size across birds . in juveniles and immature birds the underside of the wing has a narrow white band , formed by the large lower wing coverts ( the so - called ‘juvenile’ band ) , which serves well to distinguish steppe eagles of this age from other eagle species .
steppe eagles tend to nest on the ground , or in bushes , and occasionally on electricity pylons and other artificial structures . ground nesting allows a good view of surroundings , for protection , but as habitat loss and habitat conversion to agricultural land occurs more , the steppe eagle has to use higher nest sites . the nest is made of sticks and twigs , and is lined with camel dung and old rags . it is usually around 1metre in diameter .
the steppe eagle will produce a pellet every day , a small package of all the parts of their food they cannot digest fully , such as the bones and fur or feathers , regurgitated . this removes the indigestible parts of food , but also cleans the digestive tract of any debris and bacteria .
watson , j . w . 1990 . bald eagle dies from entanglement in fish net . journal of raptor research 23 : 52 - 53 .
shakhyru was the first event , in which the eagle trainer drags a dead ( ? ) fox behind his horse . his eagle is then released from a nearby hilltop and judged on how quickly it can descend upon the bouncing , deteriorating fox ( it’s certainly dead at this point ) .
the current flag of kazakhstan was adopted on june 4 , 1992 , replacing the flag of the kazakh soviet socialist republic . the national flag of the republic of kazakhstan represents rectangular breadth of blue color with the sun in its center surrounded by 32 beams , and a steppe eagle flying beneath it . there is a vertical strip with national ornament near hoist . images of the sun , beams , eagle and ornament — are all gold - colored .
the sun represents the source of life and energy . it is also a symbol of wealth and abundance ; the sun ' s rays are like grain , which is the basis of abundance and prosperity . peoples of different kazakh tribes had the golden eagle on their flags for centuries . the eagle symbolizes the power of the state . for the modern nation of kazakhstan , the eagle is a symbol of independence , freedom and flight to future .
a violent and exciting sport to witness , kokbar was easily the most popular event at the festival and drew even larger crowds than the eagle hunting .
adult lesser spotted eagles also are distinguished by their yellow eyes , whereas adult steppe eagles and greater spotted eagles have brown eyes . juveniles of all three species have brown eyes . the head and wings of lesser spotted eagles are a lighter shade of brown compared to the rest of its body ; in steppe eagles and greater spotted eagles , the entire body is a dark shade of brown . lesser spotted eagles also have a small head and beak for an eagle . like other eagles in the genus
the species suffers from declining and destruction of natural habitat . the large scale destruction of steppe habitat and conversion of steppes to agricultural land ( and the following reduction of prey like gophers ) is the major reason for the decline of the steppe eagle . especially in western ranges the number of populations is decreasing . however , at the moment the number of individuals is relatively high and the species is not seen as endangered . therefore it is qualified as least concern on the iucn red list of threatened species .
threats : habitat loss is the greatest threat as their natural steppe habitat is converted into agricultural lands . they are also very susceptible collisions with power lines and wind power development .
as steppe eagles are living in areas with very few trees they often build their nests on the ground , the slope of a hill and also on bushes and power poles .
like kazakh music , kazakh dance is decidedly odd . the aim of the dance is to replicate the movements of all the great steppe animals ( all four of them ) .
as the name indicates the steppe eagle prefers open and dry landscapes as semi - deserts , savannahs and grass steppes . the birds are living up to a height of 3000 meter , but can overcome heights up to 7900 meters . an average home territory comprises between 30 and 50 square kilometers but sometimes even encompass more than 100 square kilometers .
72 - 81 cm , wingspan 160 - 200 cm . dark - brown , medium - large aquila . juvenile usually has broad whitish band along greater underwing coverts . primaries banded , iris brown ( meyburg and boesman 2013 ) . similar spp . larger than tawny eagle a . rapax and separated by width and length of gape . generally darker than lesser spotted eagle a . pomarina and paler than greater spotted eagle a . clanga and has oval nostrils rather than round as in both these species .
diet : steppe eagle uses wide variety of hunting techniques , and may catch preys by walking or flying . it often steals preys from other raptors when in flight . susliks are their favourite preys , but other rodents , terrestrial birds , reptiles and crickets are also taken . carrion is eaten during migration and on wintering areas , mainly by immature birds .

there are usually 1 - 4 eggs in the steppe eagle’s clutch . the laying of each subsequent egg takes place every 2 - 5 days , usually 3 - 4 days ( rarely up to 10 days ) . the incubation period begins with the first egg laid . the egg is white and freckled with ochre and light - brown spots of differing colour intensity and sizes . the shell is thick and coarse - grained . the size of the eggs are 62 . 5 – 80 . 1 x 48 . 9 – 60 . 5 mm , and 73 . 81 x 55 . 85 mm on average . the eggs of the steppe eagle are on average slightly smaller than that of the golden and eastern imperial eagle , but there is a strong overlap between the ranges of measurements and the classification of each species should not be determined using these dimensions . the incubation period lasts from 39 to 45 days .
federal wildlife laws such as the bald and golden eagle protection act generally criminalize the killing of eagles and other migratory birds and the possession or commercialization of the feathers and other parts of such birds . these important laws are enforced by the department of justice and the department of the interior and help ensure that eagle and other bird populations remain healthy and sustainable .
a research paper published on monday in the journal of the cambridge university press highlighted the threat faced by steppe eagles ( aquila nipalensis ) from veterinary diclofenac , after the corpses of two steppe eagles were found in rajasthan towards the end of 2013 and earlier this year . after these were studied over the last few months , the deadly chemical was found in their tissues , setting off alarm bells .
these closely related eagle species can be most readily distinguished during their juvenile stages . in each species , juvenile birds differ greatly compared to adults . for example , juvenile greater spotted (
once hatched , the young will stay in the nest for around 60 days . usually 2 to 3 of the young will survive to fledging . during this time the male will bring food to the female and young in the nest . the success rate of chick survival in the steppe eagle is directly linked with the population number of gophers , their main food during the breeding season .
the steppe eagle is a relatively large and handsome bird of prey belonging to the genus aquila . the species is divided in two subspecies : aquila nipalensis nipalensis and aquila nipalensis orientalis which slightly differ in coloration and size . in general aquila nipalensis nipalensis is darker and larger . usually steppe eagles achieve a body - length between 60 and 81 centimeters and a wingspan between 165 and 214 centimeters . the weight ranges between 2 , 4 to 3 , 8 kilogram and the female birds are slightly larger and heavier than their male con - species . the plumage is brown to dark brown and on the back of the head are sometimes yellow spots . flight feathers and tail are blackish . often the birds have a lighter or even white bond at the wings . the eyes are brown and the hooked tip is dark gray but in the beginning the bill is bright yellow colored . the tail is short and wedge - shaped . immature young birds are less contrasted and often have a white spot on the neck . in an age of 3 – 4 years a steppe eagle gets the adult plumage and reaches sexual maturity . in wild the lifespan reaches 30 years in captivity steppe eagles can reach over 40 years .
the bird — a large , mostly brown eagle that is slightly smaller than a bald eagle — was shot in the wing by an afghan soldier at a firing range in april . an american contractor who happened to have a background in ornithology rescued the bird and took it to a u . s . army veterinarian , who was able to splint its wing and provide medication .
electrocution is a serious problem which causes the death of many steppe eagles . the taking of young eagles out of the nest in order to sell them to western european countries also occurs [ mebs & schmidt 2006 ] .
the steppe eagle is an opportunistic feeder , usually soaring above its prey , and taking steep dives , of up to 186mph towards the prey . the strong feet and talons are used to catch the prey and kill them , before either tearing them apart with the strong hooked beak , or if they are small , swallowing them whole . they will occasionally wait outside burrows of small mammals , waiting for them to emerge .
since november 2015 , sabuko ( society for nature conservation ) is carrying out conservation activities to improve the status of the eastern imperial eagle ( aquila heliaca ) through direct conservation measures , awareness raising and education .
the festival ended with the distribution of awards to the winners . if you’ve already read “ a hitchhiker’s tale from outer mongolia , ” you’re probably expecting me to mention a certain eagle vs . wolf death match now…

saryarka - steppe and lakes of northern kazakhstan comprises two protected areas : naurzum state nature reserve and korgalzhyn state nature reserve totalling 450 , 344 ha . it features wetlands of outstanding importance for migratory water birds , including globally threatened species , among them the extremely rare siberian white crane , the dalmatian pelican , pallas’s fish eagle , to name but a few . these wetlands are key stopover points and crossroads on the central asian flyway of birds from africa , europe and south asia to their breeding places in western and eastern siberia . the 200 , 000 ha central asian steppe areas included in the property provide a valuable refuge for over half the species of the region’s steppe flora , a number of threatened bird species and the critically endangered saiga antelope , formerly an abundant species much reduced by poaching . the property includes two groups of fresh and salt water lakes situated on a watershed between rivers flowing north to the arctic and south into the aral - irtysh basin .
migration the steppe eagle is a migratory bird and emigrates from its nest in winter . in recent years , there has been data about hibernating birds within the borders of the nesting sites in kazakhstan , but this remains a random phenomenon and is not the norm . wintering steppe eagles are dispersed across the tropical grassland ecosystems and deserts of the old world – africa , india , south - east asia , to the north until the arabian desert , iran , afghanistan . pakistan and south - east china ( sichuan , hubei ) . most of the global steppe eagle population seem to winter in africa ( a . n . orientalis ) and india ( a . n . nipalensis ) . birds from the population in the volga and aral - caspian regions spend winter in the persian gulf region and in various regions of africa , and those from central kazkhstan spend theirs in the persian gulf . this has been established through satellite monitoring of 16 birds which were mainly caught in saudi arabia . in particular , in the course of winter an adult female flew from ustiurt ( kazakhstan ) to botswana , south africa and zimbabwe , while another flew from ustiurt to ethiopia , chad and sudan ( meyburg et al . , 2012 ) . the general length of migration from kazakhstan can reach 17 000 km . similar data has not yet been determined for wintering steppe eagles of the eastern subspecies nesting in russia from the altai to the amura basin .

eagle ( burkit ) hunting is a distinguishing characteristic of kazakh culture . often these birds are raised as hatchlings , however many discerning burkit trainers insist that captivity - raised birds lack natural killer instincts . these trainers prefer to capture their eagles after they’ve mature , by stealing them out of the nest . to the casual layperson such as me , stealing a full - grown , pissed - off eagle with “killer instincts” from its nest seems pretty inadvisable .
steppe eagles arrive at their summer breeding grounds around april , at the start of spring . large nests , up to a metre wide , are constructed from twigs and lined with various materials , such as old rags and camel dung . while the nests are usually placed on the ground in a position allowing a good view of the surroundings , as a result of habitat alteration and persecution , nests are increasingly being found in trees , bushes and on artificial structures . the female lays a clutch of between one and three eggs which are incubated for 45 days , with the chicks being brooded for a further 55 to 65 days before fledging . the steppe eagle is remarkably long lived , reaching up to 41 years in captivity ( 2 ) .
habitat : the main habitat - the virgin steppe , foothills , semi - deserts . in the south - east of europe habitat covers an area from romania to p . urals , and in asia - east transbaikal , argun and the yellow river valley .
a denizen of the middle east and africa , the eagle got a lift on a military aircraft after being wounded in afghanistan and cared for by navy seals . it also received some valuable assistance from new york sen . chuck schumer .
the original distribution area of the steppe eagle ranged from eastern europe to central asia ( tibet , manchuria ) and the east asian mongolia . but in europe the species is now only found in russia north and north - west of the caspian sea . formerly steppe eagles also nested in moldova , romania and ukraine but it is long extinct in those countries . outside of europe the species is found in the steppes of central asia eastwards to mongolia , eastern kazakhstan , tibet and northeastern china . in autumn the eagles migrate to their winter territories . most european birds and those from western asia spend the winter in eastern and southern africa . some also spend the winter on the arabian peninsula . birds from farther east spend the winter in india and neighboring countries .
the distance between nests in concentrated nesting sites in low hills of the steppe ranges from 0 . 8 - 2 km with an average of 1 . 2 km , 2 - 6 km , usually 4 km in denser groups and 25km in less saturated groups .
and thanks to their efforts , the eagle named mitch will finally enjoy some peace at dubacher’s sanctuary , where thousands of visitors will be able to hear the story of “this very special bird and some very special guys that saved him . ”

i timed my visit to coincide with the nomads’ burkit eagle hunting festival , a spectacular two - day pageant of kazakh culture , traditional food , equestrian sports , and giant eagles laying waste to bunnies , foxes , and one unlucky wolf .
here’s a second example of shakhyru that didn’t run quite as smoothly . i’m including it because it shows the wonderfully volatile nature of the eagles . eagle hunters only use female eagles , which are larger and more aggressive than their male counterparts .

criterion ( x ) : biological diversity and threatened species : korgalzhyn and naurzum state nature reserves protect large areas of natural steppe and lake habitats that sustain a diverse range of central asian flora and fauna and support vast numbers of migratory birds , including substantial populations of many globally threatened species . the korgalzhyn - tengiz lakes provide feeding grounds for up to 15 - 16 million birds , including flocks of up to 2 . 5 million geese . they also support up to 350 , 000 nesting waterfowl , while the naurzum lakes support up to 500 , 000 nesting waterfowl . the property’s steppe areas provide a valuable refuge for over half the species of the region’s steppe flora , a number of threatened bird species and the critically endangered saiga antelope , a once abundant species much reduced across its range by poaching pressure .

during the winter months the steppe eagle will migrate to warmer climates . around autumn they will start to move from northern breeding grounds in central asia , eastern europe , and russia . they will travel to wintering grounds across the middle east , the arabian peninsula and eastern and southern africa . they have been found to fly very long distances , with some individuals travelling 220miles in a single day . they return to summer grounds at the start of the breeding season , in april and may . during migration their diet varies considerably .
steppe eagle resembles several other eagles’ species , but the main features are the rufous patches visible on nape and neck of adults , and the large gape . numerous eagles show pale rump and white patch on back . when flying , we can see a whitish patch on the hand , and some eagles have pale inner webs on most of the primary feathers . the strong , hooked bill is dark grey with yellow cere and long gape . nostrils are oval . eyes are brown . short legs are feathered brown . talons are yellow .
because of avian flu concerns , the u . s . currently bans the import of birds from a long list of countries , including afghanistan . getting the eagle out of afghanistan and into the u . s . presented something of a bureaucratic obstacle course .
steppe eagles are migratory birds . in their breeding territories they are specialized on hunting gophers . during winter the eagles migrate to southern regions as india and near east . old birds start their flight to the breeding sites in the middle of february while young birds start around one month later .
their plumage is mostly dark brown in colour , with light barring on the flight and tail feathers . there is a patch of reddish - brown on the nape of the neck . the nostrils , or nares , are oval in shape , and the steppe eagle is the only species in aquila which the gape , or opening of the mouth , reaches beyond the eye . the beak is yellow with a dark tip . the juvenile is similar to the adult , but paler in colour , and with a broad white band on the underside of the wing .
habitat and habits : occurs in steppe , desert , semi - desert , open savanna , pastures , agricultural fields , paddy fields , grassland , and open woodland . it roosts on the ground , in groups in trees , or perches on power poles . steppe eagles are nearly always found in groups in winter , sometime numbering more than a hundred birds , and often in association with other raptors , especially black kites and lesser spotted eagles . this species appears sluggish , spending much of its time perched on rock piles , the ground , or telephone poles ) . more . . . .
hickman cared for the bird for several months , enlisting a colleague to help build it a spacious cage and feeding it by hand with whole chickens he obtained from a local cook . although it began to recover , the eagle would not be able to fly . hickman sought help from agencies in the u . s . , but got nowhere . one expert at a refuge in british columbia offered advice on caring for the bird , but was skeptical , wondering if hickman could provide it with a high enough quality of life to justify keeping the eagle alive .
the steppe eagle is an extremely widespread species , which makes long - distance migrations between summer breeding grounds and wintering sites . subspecies aquila nipalensis orientalis breeds in extreme south - east europe , southern parts of the russian federation , and central asia as far east as eastern kazakhstan . during the winter , it migrates to the middle east , the arabian peninsula and eastern and southern africa . by contrast , aquila nipalensis nipalensis breeds from the altai mountains , south to tibet , and east as far as north - east china and eastern mongolia , and mostly winters in southern asia ( 2 ) .
sabuko is also carrying out satellite tracking of juvenile birds with the help of mme and the vashlovani protected areas office . to raise awareness among locals , sabuko is conducting activities such as eagle watchers’ training , talks and presentations in schools , and meetings with municipality representatives , farmers and landowners .
lesser spotted eagles are medium - sized birds ( body length 54 to 65 cm ) , generally smaller than steppe eagles ( aquila nipalensis ) ( 60 to 81 cm ) and greater spotted eagles ( a . clanga ) ( 59 to 71 cm ) . the largest of these three species are steppe eagles , weighing 1 . 8 to 3 . 8 kg . thus , despite their relatively large size , lesser spotted eagles only weigh 1 . 2 to 2 . 2 kg , with an average of 1 . 6 kg . greater spotted eagles are just slightly heavier ( 1 . 4 to 3 . 2 kg ) than lesser spotted eagles .
the main diet of the steppe eagle during the summer consists of small mammals , especially gophers and suslik ( small squirrels ) , but also small birds , insects and reptiles . during the winter months they will rely heavily on winged harvester termites , and become more resourceful in finding food . some have been witnessed , in south africa , to ambush burrowing blind and semi - blind mole rats , by watching the soil for movement , to then plunge their feet into the ground and seize them . they will also take carrion when migrating , and have been known to steal food from other raptors , in mid - flight .
lesser spotted eagle females lay two eggs and stay with them continuously while males forage for food . after the eggs hatch , both parents tend the helpless , altricial young until fledging occurs , typically after 8 weeks . siblicide is common in this species , thus only one offspring typically survives to fledge .
in april 2007 , the azerbaijan ornithological society ( birdlife in azerbaijan ) started a comprehensive survey of imperial eagles in the northwestern part of azerbaijan . data collected during this survey were the first and most detailed data about the eastern imperial eagle for azerbaijan . in nine days , they covered 6 . 000sq km ( 7 % of azerbaijan territory , which is 25 % of the habitat suitable for the eastern imperial eagle ) where they found 25 breeding pairs of eastern imperial eagles and a five more active territories . it was estimated that for the studied area , the number of breeding pairs was 35 - 60 .
the eagle landed in virginia friday morning , and was then flown to new york by a pilot with the volunteer organization pilots n paws . it will be kept under quarantine for 30 days before inhabiting its new home at the berkshire sanctuary , where caretakers will keep it strong on chicken and “ratsicles . ”
interesting fact : eagle has very sharp , vision with broad coverage . each eagle eye is able to focus directly on the 2 items . visual acuity allows to see a hare at a distance of over three kilometers and a peripheral glance it can reach 270 degrees . with altitude eagle is able to see the production on the surface of 11 . 5 square kilometers . eagles effective in the hunt . they do not kill the extra animals are caught only for their own food and chicks . mainly small game hunting . eagles not only independently gather food , but also willing to engage in a frank robbery . for example , they can take away the prey from a small bird of prey on the fly . eagles excellently hunt flying birds . overtakes them unawares victim , prey to such a height that the bird does not see them . then dive with such speed that their production does not have time to notice .
