the pheasant cuckoo ( dromococcyx phasianellus ) is a species of neotropical cuckoo in the subfamily neomorphinae of the cuculidae family .

it is native to central and south america where it occurs in lowland tropical forest .

the pheasant coucal is the only australian cuckoo to build its own nest . it also lives and nests on the ground , unlike other cuckoos .
the pheasant cuckoo ranges from southern mexico to argentina , throughout forested regions of central america and the middle and southern amazon basin . in panama , the pheasant cuckoo can be found along the pacific slope and canal area . uncommon and local , its true distribution is not well known due to its highly secretive behaviors .
range : the pheasant cuckoo is found from s mexico to panama , colombia , venezuela , the guianas , ecuador , brazil and amazonian peru , and then , in bolivia , paraguay and n argentina .
the pheasant cuckoo is a terrestrial species , but it flies well and quickly , and even silently during the territorial displays . nothing is known about migrations but this species is probably resident in its range .
this phase lasts 2 - 15 seconds or longer , according to the type of prey . then , the pheasant cuckoo starts a new sequence “bob - rush - peck” . it may forage for several hours every day .
the pheasant cuckoo female lays a dull white or pale buff egg with some rufous spots in the nest of the chosen host while this one is absent . the host species will provide parental care to egg and chick until the young bird becomes independent . the young cuckoo probably ejects host’s eggs and / or chicks from the nest .
when the cuckoo nestling hatches , it instinctively pushes the other eggs and nestlings out of the nest .
common cuckoo is not the only brood parasite in the family . some tropical american species , such as striped cuckoo and pheasant cuckoo , also lay eggs in the nests of other birds . and so do yellow - billed and black - billed cuckoos — sometimes . while yellow - billed cuckoo normally raises its own young , it lays eggs in the nests of other birds surprisingly often . other yellow - billed or black - billed cuckoos are the most frequent hosts , but it has been known to target at least 10 other species , from robins to cardinals .
the pheasant cuckoo is rare and difficult to see as it does not move much and remains inconspicuous . it favors terra firme forests and is known to range at elevations of up to 1000 m along the foothill of the andes . it also occurs in
habitat : the pheasant cuckoo frequents the understorey of the tropical lowland evergreen forest , but it also can be found in river - edge forest and tropical deciduous forest . this species can be seen from sea - level up to 1600 metres of elevation .
the pheasant coucal feeds on the ground on large insects , frogs , lizards , eggs and young of birds and , sometimes , small mammals .
protection / threats / status : the pheasant cuckoo has wide range , but the species is affected by changes and fragmentation of its habitat . however , it also benefits from new suitable habitat due to degradation of some areas . with its secretive and solitary behaviour , this species appears uncommon , rare or local . the global population was placed in the band 50 , 000 / 499 , 999 individuals in 2008 . it is suspected to be increasing . but currently , the pheasant cuckoo is evaluated as least concern .
the pheasant coucal is a large , long - tailed , pheasant - like cuckoo which occurs in northern and eastern australia , as well as southern new guinea and timor - leste . unlike most species of cuckoos , the pheasant coucal builds its own nest , a shallow platform of sticks and grass , into which it lays between two and five white eggs . the young coucals are fed by both sexes , but the male parent does most of the feeding , providing the nestlings with small vertebrates , such as frogs , and grasshoppers and other insects .
) in appearance and mannerisms , apparently frightening the potential host and allowing the cuckoo to approach the nest unmolested .

the cuckoo call on half and full hours , the music plays on the full hour whereas the hand painted figurerines dancing .
when perched , usually in the open at the top of a tree , the cuckoo drops its wings below the level of its tail , as in the photograph . the best places to see cuckoo are grassland , reed beds , and edges of woodland .
this is the first record of pheasant cuckoo from bci in decades ! it is one of the large - bodied wet forest birds that famously disappeared a few decades after lago gatun ( in which bci is situated ) was created . presumably this same bird was present for 2 years after its initial discovery .
in flight , the cuckoo can be easily mistaken for a sparrowhawk or kestrel , because it has swept - back wings and long tail . however , sparrowhawks do not have pointed wings like the cuckoo , and the kestrel is streaked and not barred on the underparts .
the cuckoo is a brood parasite , it lays its eggs in other birds ' nests and leaves the host birds to incubate and rear its young . dunnocks , robins and meadow pipits are frequent host birds . each female cuckoo specialises in using a particular host species and will lay eggs with similar markings to the host bird ' s eggs , and the young cuckoo will imitate the begging calls of the host ' s chicks .
mimicry , in which the cuckoo egg resembles that of the host , thus minimizing rejection by the host ; removal of one or more host eggs by the adult cuckoo , reducing both the competition from host nestlings and the danger of recognition by the host that an egg has been added to the nest ; and nest - mate ejection , in which the young cuckoo heaves from the nest the host’s eggs and nestlings . some species of
pheasant coucals have benefited from land clearing where weedy thickets have grown up , especially of blackberry or lantana . however have been adversely affected by widening urban development and where overgrazing by livestock has occurred .
pheasant cuckoo rattling sounds during foraging . these sounds apparently are produced by vibration of the wing and tail feathers , and vocalization . these sounds accompany body , wing and tail movements that apparently function in flushing potential prey . then the typical song : two introductory whistles of successive higher pitch followed by a trill ( whee whee wheerr - rr ) .
generally , if you hear a cuckoo singing you will probably not see it until it stops singing , which is when it flies away from its song post .
…two very distinct families , the cuckoo s ( cuculidae ) and the hoatzin ( opisthocomidae ) . family cuculidae is the much larger group , containing about 140 species of cuckoo s , roadrunners , coucals , couas , malkohas , guiras , and anis ; cuculids are found in the tropical and temperate zones of all the continents
a large ' pheasant - like ' , ground - dwelling cuckoo , the pheasant coucal has a long tail and short rounded wings . in its breeding plumage , it has a black head , neck and underbody with the upperparts and wings reddish - brown with black and cream barring and the black tail is barred orange . out of breeding , the head and back return to a reddish chestnut colour and the underparts are cinnamon brown , with all streaked boldly white . the eye is red . sexes are similar in plumage , but females are larger than males . young birds look like paler , non - breeding adults with orange spots on the head , neck and upper body . when disturbed , coucals run rather than fly , or fly clumsily , plunging into cover . unlike most other cuckoos , the pheasant coucal is not a nest parasite .

reproduction of this species : the breeding season may vary according to the range , but the male sings from march to august in mexico and from april to july in panama . the pheasant cuckoo is a brood parasite , and its hosts are typically passerines which make covered , domed nests . this type of nest is that of tyrannid flycatchers of genera tolmomyias , myiozetetes , rhynchocyclus , fluvicola and thamnophilus .
cuckoos belong to the family cuculidae , well known for parasitic behaviour where they lay their eggs in other nests and leave the chick rearing to other birds . not all of them practice this parasitic behaviour . in australia the pheasant coucal and the brush cuckoos build their own nests . the channel - bill cuckoo and the koel mostly use black and white birds to rear their young . it is not uncommon to see a channel - billed cuckoo following crows or a common koel with peewees . the smaller cuckoos are known to use host nests from wrens , thornbills , warblers and honeyeaters .
pheasant cuckoos also have some other interesting behaviors . males are territorial , and in response to singing males , they will raise their head and crest , puff out their breast feathers , partially extend their wings and arch their tail coverts . even more interesting , the pheasant cuckoo has a unique , stylized foraging behavior . it descends to the ground , walks in the leaf litter and produces rattling sounds by vibrating its wings , body and tail feathers , as well as bill clapping . it bobs its body then lunges forward , taking several short steps , picking at insects among the leaf litter . it feeds on arthropods and small vertebrates such as lizards . it is also known to eat small nestling birds .
this charming and inexpensive cuckoo clock is one of our most popular models . the leaves and birds are hand carved from solid linden wood . when the clock strikes the hour or half - hour the door opens , a cuckoo appears and calls along with the clock ' s gong strike . at the same time , the two birds below move to feed the baby chicks in the nest .
behaviour in the wild : the pheasant cuckoo feeds on large insects such as grasshoppers , cicadas and beetles , but it also takes small lizards and nestling birds . the foraging behaviour of this species involves sounds and feather movements , probably used to flush the preys hidden in the vegetal cover and the leaf litter . a low rattle is produced by wing and tail feather vibration and bill - clapping . other fluttering noises are also heard during the distinct phases of the foraging behaviour .
calls and songs : sounds by xeno - canto the pheasant cuckoo utters melancholy whistles “se - sée - werrrrrr” with quavering note at the end . sometimes , the terminal trill is lacking in the song . it also gives series of “sah , she - si - see” notes rising in pitch . it often sings from elevated perch , usually outside the thick vegetal cover . other calls such as rattles , clucking and growling can be produced too , especially while searching for preys on the ground .
. the pheasant cuckoo is overall gray with a pale belly . the throat and breast are brownish with dark specks . it has a pale superciliary line from the base of the culmen to the nape , and a rufous crest . the tail is long , broad , and graduated . it has extremely long and ornate rump feathers and uppertail coverts . it forages on the ground where it extends the wings and tail to flush insects before it chases and catches them . it is very similar to the
, any of numerous birds of the family cuculidae ( order cuculiformes ) . the name usually designates some 60 arboreal members of the subfamilies cuculinae and phaenicophaeinae . in western europe “cuckoo , ” without modifiers , refers to the most
. . . bornean ground - cuckoo carpococcyx radiatus a widespread endemic , occurring in low densities ( long & collar 2002 ; mann 2008 ; payne 2005 ) . this species was heard at pj in 2005 . . . .
the family cuculidae is worldwide , found in temperate and tropical regions but is most diverse in the old world tropics . cuculids tend to be shy inhabitants of thick vegetation , more often heard than seen . many species are named for the sounds they make—e . g . , brain - fever bird ( a hawk cuckoo , cuculus varius ) , koel ( eudynamys scolopacea ) , and cuckoo itself , the latter two names being imitations of the bird’s song .
the pheasant cuckoo can be aggressive in territorial behaviour . a male responds to other singing male with strutting displays . head and crest are raised , the breast feathers are puffed out , and primaries and alula are partially extended to display the white spots while the uppertail - coverts are raised and argued . they make frequent pauses on logs and trees , while briefly gaining height over one another . after several minutes , the first male comes to the ground while the second male flies away from the area . other types of threat displays may occur .
since the early 1980s , the numbers of cuckoos has been in decline and this may be because the populations of some key host species , such as dunnock and meadow pipit , have also declined . consequently , the cuckoo is now red list species .
the pheasant coucal prefers dense understorey vegetation , particularly grasses , rushes , bracken and sedges , in open forests and woodlands , and around wetlands . often found in sugar cane plantations near wetlands , on farmlands with thick grasses and weed - infested thickets , such as lantana . often seen in parks , gardens and along roads or railway lines .
caterpillars and other insects such as beetles and ants form the major part of the cuckoo ' s diet . many of the caterpillars are the hairy or brightly coloured poisonous ones , but their digestive system is specially adapted to cope with the hairs and toxins .
pheasant cuckoos inhabit lowland tropical forest , and can be found in dense thickets , secondary growth forest and borders up to 1200 meters . rarely seen , they are vocal and are often heard . their call is similar to that of striped cuckoo , two clear notes followed by a quavering third note or sequence of two or three quick short notes . they call ventriloquially from branches in the lower and middle levels of the forest , in dense cover , and are often difficult to detect . in panama , they call most frequently from mid - april to july , during the onset of the wet season .
this clock is hand made in the black forest in germany . the mechanical brass movement is driven by two weights and time escapes with the tick of a traditional pendulum . the cuckoo call sound is made by two wooden whistles with bellows inside the clock case .
, found in all of the cuculinae and three species of phaenicophaeinae . it consists of laying the eggs singly in the nests of certain other bird species to be incubated by the foster parents , who rear the young cuckoo . among the 47 species of cuculines , various
. . . bornean ground - cuckoo carpococcyx radiatus borneo - endemic we heard this elusive species calling once on 15 march in the traditional forest at pinang jatus . glpf is a new locality for this species ( long & collar 2002 ; mann 2008 ) . . . .
the european cuckoo ( cuculus canorus ) is a brood parasite ; i . e . , it lays its eggs in the nests of other birds , which act as foster parents for the young cuckoos . the most frequent foster parents are various species of small songbirds . although the…
the pheasant coucal is found in northern and eastern australia , as well as new guinea and east timor . it is found from the pilbara , western australia , to south - eastern new south wales . in new south wales it is mainly found east of the great dividing range from the queensland border to the southern hunter region , with some around sydney and further south to illawarra .
when i was a boy , i used to hear cuckoos calling at summertime , but that is nearly 30 years ago and now they are essentially never heard . that said , on 8 th july 2006 , a cuckoo was heard calling at least 3 times , which was a real delight .
pheasant coucals form lasting pairs and , unlike other australian cuckoos , build their own nests and raise their young themselves . the nest is usually hidden in thick grass or sugar cane or in weedy thickets and is a platform of sticks , grass or rushes , lined with leaves and grasses . the male usually incubates the eggs and feeds the young , with the female helping with feeding . more than one clutch can be laid in one season .
. . . the total number of records is low but still considerably higher than in any previous study . both species are rarely seen and , islandwide , the total number of recent ( 1992–2002 ) localities number only nine and thirteen for bornean groundcuckoo and bornean peacock - pheasant , respectively ( collar et al . , 2001 ; long & collar , 2002 ; s . van balen , pers . comm ; gmf , unpubl . . . .
contributing editor kenn kaufman provides tips for identifying birds in every issue of birdwatching . in june 2014 , he tells what to look for to identify yellow - billed cuckoo — and to tell it from similar - looking black - billed and mangrove cuckoos . he also offers this interesting description of the yellow - billed’s unusual breeding habits :
. . . habitat : lumadan : mature rubber , new plantations , swamp , and dipterocarp forest . lumbidan : circumstantial evidence from specimens indicates peatswamp forest ( hooked - billed bulbul and grey - breasted babbler ) and lowland , riverine forest ( bornean ground cuckoo ) ( long and collar 2002 banks ( 1982 , pers . comm . ) . . .
. . . low obtained a few birds along the menggalong river as well . among birds collected in 1899 was bornean ground cuckoo ( long and collar 2002 ) . it is home to two of the most habitat - specific bird species in the state , hook - billed bulbul and white - throated babbler ( sheldon 1987 , holmes andwall 1989 ) . . . .
. . . comm . ) . most of the bornean ground - cuckoo vocalizations we heard are described in detail by long & collar ( 2002 ) , although we do not always share their interpretation of the function of the calls . the vocalization of bornean peacock - peasant has been described as a harsh loud double ' cack - cack ' ( r . sözer , pers . . . .
. . . reports from ksnp have found that amongst hunters and bird - trappers the sumatran ground cuckoo was not well known ( holden 1997 ) , possibly because this species is rare and therefore difficult to find or because it has an unpleasant taste and is therefore not targeted ( long and collar 2002 ) . however , the other terrestrial bird species recorded in this study may be more vulnerable to poaching . . . .
young yellow - billed cuckoos develop with amazing speed . the eggs hatch after only 9 - 11 days of incubation , and the young may be ready to leave the nest 8 days later , even though not full - grown then . ( for comparison , a robin’s incubation period is 12 - 14 days , and the young usually fledge in about 13 days . ) obviously , rapid development is an advantage for a brood parasite , since the cuckoo’s egg is laid later than those of the host , and the young bird must catch up to be fed by the foster parents . — kenn kaufman

justification : this species has an extremely large range , and hence does not approach the thresholds for vulnerable under the range size criterion ( extent of occurrence < 20 , 000 km2 combined with a declining or fluctuating range size , habitat extent / quality , or population size and a small number of locations or severe fragmentation ) . the population trend appears to be stable , and hence the species does not approach the thresholds for vulnerable under the population trend criterion ( > 30 % decline over ten years or three generations ) . the population size is very large , and hence does not approach the thresholds for vulnerable under the population size criterion ( < 10 , 000 mature individuals with a continuing decline estimated to be > 10 % in ten years or three generations , or with a specified population structure ) . for these reasons the species is evaluated as least concern .
partners in flight estimate the total population to number 50 , 000 - 499 , 999 individuals ( a . panjabi in litt . 2008 ) . trend justification : the population is suspected to be increasing as ongoing habitat degradation is creating new areas of suitable habitat .

bird not seen but heared clearly for about 1 hour . for sure it was perched inside the bushes , about 50 m from my position .
the area presents very dense rainforest , with old trees , and some human intervention .
this bird sang two songs at about 10 : 15 and at about 10 : 25 , evidently from the ground . at 10 : 28 , i played two songs from xc83089 and within 10 seconds he flew in , landed on a branch about 5 m from the ground , and sang . after the five songs in this recording , he flew over our heads , landed in the forest farther away , and sang about eight more songs . between the third and fourth songs , i spliced - in some time from another part of the recording to replace talking by some people .

the adult has dark sooty brown upperparts . scapulars and wing - coverts have pale - edged feathers involving scaled effect . the flight feathers are dark greyish - brown . rump and uppertail - coverts are dark greyish - olive , with small white tips to uppertail - coverts . the long , graduated tail is dark greyish - brown with narrow white terminal band . the underparts are white , but the breast is mostly whitish - buff with dark brown streaks and spots . axillaries and underwing - coverts are white , but the flight feathers and the tail are greyish - brown .
on the head , there is a short , rufous crest on the sooty brown crown . we can see a white eye stripe , indistinct on lores but conspicuous in postocular area . ear - coverts are dark brown , whereas the malar stripe is whitish . the bill is blackish above and greyish below . the eyes are yellowish , surrounded by bare , yellow - green eyering . lores are bluish - green to greenish - grey . long legs and feet are greyish - brown . the feet are zygodactyl with two toes backwards and two toes forwards . both sexes are similar .
the juvenile resembles adult but sides of head and upper breast are washed buff , and streaks and spots are absent . crown and crest are dull greyish - brown . wings , tail and uppertail - coverts show reduced white tips . the eyes are dark brown .
the first phase or “bob” shows the bird on the ground . its body , wings and tail are bobbing up and down . the tail is fanned and brushes gently the leaf litter . after a short pause , the second phase or “rush” shows the bird running forwards in several short , quick steps . the head is outstretched and low . the wings , and especially primaries and alula , are extended out and downwards below the body - level , and flick forwards intermittently . bill - clapping can be heard and the fluttery rattle noise is increasing throughout the “rush” . the bird stops abruptly after 1 - 2 seconds , ceasing both noise and movement . the third phase or “peck” shows the foraging bird pecking in the leaf litter , capturing some preys and searching for invertebrates on the ground while walking .
little is known about the courtship displays of this species , but we can suggest that they are fairly similar to the previous displays , in order to enhance the long , white - tipped wing and tail feathers while the crest is raised . but usually , the pair - bonds are not very strong between the mates .

the adult birds usually have blue - grey head , breast and upperparts , and horizontal barring on the underparts and white spots and tips on the tail . however , the female also exists as a rare rufous
hepatic
morph , so instead of being grey it is red - brown . the eyes and legs are yellow and the slightly curved bill is horn - coloured .
juveniles are similar to the rufous female , but with a white patch on the nape .
the female will also sometimes eat the eggs and nestlings of the host bird ( see nesting ) .
they are a summer migrant , arriving around april and returning to central and southern africa from mid - july to august . the juveniles follow in august and september .

local breeding populations of yellow - billed cuckoos can vary from year to year . they may concentrate where populations of tent caterpillars , cicadas , or other large insects have exploded . there’s some evidence that the cuckoos may lay more eggs during such times of abundance and may be more likely to leave the “extra” eggs in the nests of other birds .

learn how the birds of cozumel were affected by hurricanes emily and wilma in 2005 .
a bird born to run , the greater roadrunner can outrace a human , kill a rattlesnake , and thrive in the harsh landscapes of the desert southwest . roadrunners reach two feet from sturdy bill to white tail tip , with a bushy blue - black crest and mottled plumage that blends well with dusty shrubs . as they run , they hold their lean frames nearly parallel to the ground and rudder with their long tails . they have recently extended their range eastward into missouri and louisiana .
the best way to find greater roadrunners is to travel along quiet roads in open country , particularly arid grasslands and low deserts . seeing one is usually a surprise , as the bird darts out of shrub cover or across a road—so keep your eyes peeled . roadsides often teem with roadrunner prey lizards and snakes basking in the open or mice and birds drawn to seed - bearing plants . on the edges of its range , the greater roadrunner can be quite scarce and very hard to find . listen for their dovelike , low - pitched , cooing , which they usually give from an elevated perch .
for a generation of americans , the familiar “beep , beep” of warner brothers’ cartoon roadrunner was the background sound of saturday mornings . despite the cartoon character’s perennial victories over wile e . coyote , real - life coyotes present a real danger . the mammals can reach a top speed of 43 miles an hour—more than twice as fast as roadrunners .
roadrunners have evolved a range of adaptations to deal with the extremes of desert living . like seabirds , they secrete a solution of highly concentrated salt through a gland just in front of each eye , which uses less water than excreting it via their kidneys and urinary tract . moisture - rich prey including mammals and reptiles supply them otherwise - scarce water in their diet . both chicks and adults flutter the unfeathered area beneath the chin ( gular fluttering ) to dissipate heat .
greater roadrunners eat poisonous prey , including venomous lizards and scorpions , with no ill effect , although they’re careful to swallow horned lizards head - first with the horns pointed away from vital organs . roadrunners can also kill and eat rattlesnakes , often in tandem with another roadrunner : as one distracts the snake by jumping and flapping , the other sneaks up and pins its head , then bashes the snake against a rock . if it’s is too long to swallow all at once , a roadrunner will walk around with a length of snake still protruding from its bill , swallowing it a little at a time as the snake digests .
based on banding records , the oldest roadrunner was at least 7 years old .
roadrunners hold a special place in native american and mexican legends and belief systems . the birds were revered for their courage , strength , speed , and endurance . the roadrunner’s distinctive x - shaped footprint—with two toes pointing forward and two backward—are used as sacred symbols by pueblo tribes to ward off evil . the x shape disguises the direction the bird is heading , and is thought to prevent evil spirits from following .

replace their habitat – plant a shrub or a bush not just a tree ! trees need to connect to enable safe passage for the birds . any open area makes them vulnerable to be attacked by natural predators , like kookaburras , hawks , falcons , snakes , owls and the introduced predators such as cats , dogs , foxes or indian mynas .
be a responsible companion animal guardian . keep your cat inside or in a cat enclosure . always supervise your dog – especially during spring and summer and den your dog at night .
you can help by keeping your rubbish in a bin where black and white birds can’t get at it . firstly because they forage in it inadvertently getting it caught around their feet , body or beaks , and secondly they use it as nesting material . basically they will use string , twine , wire , wool , netting , basically any material they can find to build a nest . when the chicks grow up in the nest , their feet and legs often get entwined in this string . many of these birds become attached to the nest and the tree branch . they are tethered to the nest like on a lead and when they fledge ( try to leave the nest to fly ) they are either totally unable to leave or injured and deformed rendering them unable to forage , perch and therefore live a healthy life .


bell 's sparrow ( artemisiospiza belli ) is a medium-sized sparrow of the western united states and northwestern mexico .

it used to be placed in the genus amphispiza , but recent evidence suggested it be placed in its own genus .

four populations are resident to the west : subspecies canescens breeds in south-central california , the dark nominate subspecies belli in the california coast ranges and part of the western slope of the sierra nevada south to about 29 ° n in baja california , the equally dark subspecies clementeae limited to san clemente island , and subspecies cinerea in western baja california from 29 ° n to 26 ° 45 ′ n .

the aou now considers bell 's sparrow a separate species , formerly grouped with the sagebrush sparrow , and together previously known as the sage sparrow .

bell 's sparrow is difficult to separate in the field from the sagebrush sparrow .

both species measure about 6 in ( 15 cm ) long and weigh approximately 16.5 g ( 0.58 oz ) .

in general , with bell ’s sparrow the malar is darker than the head while on the sagebrush it is about the same shade of darkish gray .

bell ’s sparrow also has a thicker malar strip than sagebrush .

the amount a streaking on the back as well as the shade of the mantle may also be used to separate the two , but this is affected by wear on the feathers .

bell 's also has little or no white in the tail , but this field mark alone may not be diagnostic .

bell 's sparrows are indeed often tied to sagebrush habitats , although they can also be found in brushy stands of saltbush , chamise , and other low shrubs of the arid west .

the subspecies a. b. clementeae has been listed as threatened since 1977 .

the species ' common name and binomial ( belli ) refer to john graham bell .

bell ' s sparrow

taxonomy can be confusing , even for the experts . in the nineteenth century all the “sage” sparrows from the rocky mountains west to the pacific coast were known as bell’s sparrow , although ornithologists noted there were several regional forms . by 1910 they had split bell’s sparrow into the two distinct species we know today , but a revision in 1957 lumped them together as the sage sparrow . in 2013 they were split back into two species , now known as the sagebrush sparrow and bell’s sparrow .
the oldest known bell’s sparrow was at least 9 years , 3 months old when it was recaptured and re - released at a california banding station .
contrast between the head and the malar stripe , along with the strength of the malar seems to be one of the most reliable fields marks . on bell’s sparrow the malar is darker than the head while on sagebrush it is about the same shade . bell’s sparrow also has a thicker malar strip than sagebrush .
nina , both of those would be sagebrush sparrow . bell’s in winter hasn’t been recorded east of phoenix and sagebrush is the only one that breeds in az .
bell’s sparrow is more local in arizona than in california and the reverse is true of sagebrush sparrow . bell’s sparrow does not breed in arizona , but sagebrush sparrow does breed in the great basin portion of california . both species winter in the salton sink , but like the the lcrv the status of each has yet to be worked out . the status of sagbrush sparrow as a migrant ( and possibly in winter ) in the mojave desert is largely unknown . within the arizona portion of the mohave desert at places such as the sacramento valley it appears to be largely sagebrush sparrow ( again see comments on id below ) . bell’s sparrow has been found east to phoenix in arizona , but how regular is it east of the lcrv ?
song ' s and calls from a group of three bell ' s sparrows . the birds were chasing each other through the saltbush and sagebrush . call quality a , song quality c .
the bell’s sparrow is a neat , gray - headed sparrow emblematic of california’s coastal sage and chaparral . they also occur in baja california , the mojave desert , and on san clemente island , california ( a federally threatened subspecies ) . like the very similar sagebrush sparrow , these birds spend much of their time foraging for insects and seeds on the ground underneath shrubs . in spring males sing a fast mix of trills and chips from the tallest perches they can find .

amount of white in the tail has been cited as a field mark for sagebrush vs nominate bell’s . though it is variable the amount of white ( sagebrush ) vs buffy ( bell’s ) in the outermost rectrices may be of some use . another field mark that if useful would likely be difficult to use in the field .
caution is warranted as we learn about identification of the two species , and for the time being it may be best to leave most birds on the winter grounds as “sage” sparrow or use the modifier presumed / probably . that being said with practice i think most individuals are identifiable in the field . check out this photo of a bell’s sparrow and this one of a sagebursh sparrow posted online . notice the head color in both individuals and despite the photo of the sagebrush sparrow looking like it has a darker head , the contrast between the head and the malar is minimal . the bell’s sparrow shows a strong contrast between the malar and the head . notice also the amount of streaking on the back of each individual ; this characteristic , though , needs further evaluation and should be used possibly only as a supporting characteristic . robert royse’s webpage has a nice selection of both species ( along with nominate bell’s sparrow ) , though more location data would be useful to assure yourself that they couldn’t have been a different taxa than that listed . i also recommend checking out this urltoken post on the identification by song . finally birding is fun has a nice review of the split .

given that sagebrush and bell’s were once considered to be one species , differences between habitat preferences on their wintering grounds are not well - studied . regional conservation plans that might consider conservation strategies for sage sparrows’ wintering habitat were likely written before the taxonomic split , and just as many listers found themselves with only an unsatisfying sagebrush / bell’s sparrow on their lists after the split , the species themselves are left with a similarly unsatisfying , generic conservation strategy .
initial impressions suggest that bell’s sparrow winters farther east than was generally expected . in absence of detailed field study of multiple markings mentioned by pyle above , we encourage observers to report their observations of wintering individuals as bell’s / sagebrush sparrow ( sage sparrow ) from pima , pinal , and maricopa counties in arizona , as well as in counties in western arizona and southeastern california . careful scope viewing is highly recommended , and one’s impressions of important field markings are definitely impacted by lighting conditions in the field . we have found that it may take me an hour to achieve good looks at only a small fraction of the many wintering artemisiospiza one might find at a location . further , we suggest observers photograph these whenever possible throughout the species’ ranges , and it is always useful to describe the vegetation where you find birds .
birders of the arid southwest have been experiencing headaches this winter , and it is not just dehydration . the recent aou split ( here ) of sage sparrow into two distinct species , bell’s sparrow ( artemisiospiza belli ) and sagebrush sparrow ( a . nevadensis ) , has led to an outbreak of head - shaking and hand - wringing on blogs , listservs , identification discussion groups , and even reviewer discussion groups in the region . chris mccreedy of point blue conservation science provides us with an overview of the challenges and the field work being done to supply some answers .

presumed bell’s sparrow at quail hollow in parker strip ca on 19 jan 2013 . another look at the same individual where you can better see the thick dark malar extending up to the bill , strongly contrasting with the rest of the head . note also again the thin back streaking that is hard to see . copyright ( c ) 2013 david vander pluym
bell ' s sparrow pair reported between mile markers 7 . 1 and 7 . 2 on blue ridge road in mix canyon . the habitat was chamise and manzanita chaparral mixed with oak woodland . male sparrow immediately perched high and visible in shrub when playback was called and began singing . female hid in shrub nearby . all bird species were singing in the early morning chorus ( wrentits , spotted towhees and california thrashers most prominent ) . weather was sunny , clear with a light breeze .
i haven’t explored the blythe area south enough in winter to give good sites there but check urltoken for good locations there . the parker strip is likely your best bet for sage sparrows in california , as along the river there are still nice patches of suaeda . good spots to check include the brush areas around quail hollow day use area and the crossroads campground . i’ve had birds matching bell’s sparrow at both spots ( but see below on problems of identification ) . on the arizona side your best bets are probably pintail slough on the havasu nwr where i’ve also had birds matching bell’s . i’ve had them once in the parker valley and it is likely still worth checking , but that area has lost a lot of habitat to agriculture which is typically unsuitable for sage sparrow . kohen ranch in the bill williams river nwr is another site i have had the species and is worth the hike in winter to check out . interestingly these areas all have a lot of atriplex ( saltbush ) which bell’s sparrow breeds in , perhaps there is some ecological partitioning on the wintering grounds ?
sage sparrow is a terrestrial inhabitant of arid lands including desert with sagebrush and saltbush , open slopes with juniper and pinyon , and chaparral with sagebrush , greasewood , baccharis , and cactus . it inhabits elevations from sea level to about 2000 m . adults have a gray head and white eye ring , a white dot over the lores , black and white malar and sub - malar ( moustache ) stripes , white underparts with a dark breast spot . resemble immature black - throated sparrow ( amphispiza bilineata ) but lack that species’ white supercilium . sage sparrow is widespread in the western u . s . ( races nevadensis and canescens ) , nesting as far north as washington , eastward to wyoming and colorado , and west to california . birds of the western u . s . ( except coastal california ) migrate southward as far south as sonora and chihuahua , mexico . the distinctive race belli of western california ( bell’s sparrow ) nests southward into baja california norte . it is slightly smaller ( length 14 . 5 cm ) and has a smaller bill . it has a darker gray head , a broader black moustache stripe , and is richer brown on the mantle , wings , flanks , and tail . in the central portion of the baja peninsula , bell ' s sparrow is replaced by the similar but paler race cinerea .
by now i am sure that most everyone has heard about the split of sage sparrow into ( at present ) two species : bell’s sparrow ( artemisiospiza belli ) and sagebrush sparrow ( a . nevadensis ) , two names i think are appropriate or at least i can’t think of anything else better . bell’s has multiple subspecies within it and for the purposes of this blog post , all mention of bell’s sparrow refers to a . b . canescens . it is interesting to note that this split is not without its detractors and it is well worth reading the proposal , as well as the literature cited . especially worth reading is patten and unitt 2002 ( claims that canescens is not a valid taxa and should be lumped with nevadensis ) and cicero and johnson 2006 ( which is a rebuttal to the prior paper’s claims ) . really it is a good idea to read over all proposals you have an interest in , as well as any of the publications you can get your hands on ( important parts of which can be left out of the proposals ) . read it and decide for yourself if you agree with the committee decision ! i know i don’t always agree with the decisions , but after reading the material present and committee comments , i can at least usually understand the rationale behind it . anyway i’m getting way off the topic of sage sparrows .

prominence of a supercilium has been cited , but this seems to be variable as well , a complete lack of any pale area in the supercilium may be only found in bell’s , but this could be nearly impossible to tell without a bird in the hand .
same individual as xc382447 and xc382448 . the bird was making this call and hopping between sagebrush ( artemesia sp . ) in a rectangular pattern . it was unclear whether the bird was agitated with my presence , or the presence of other nearby bell ' s sparrows .
13·7–15·7 cm ; 12·7–16·8 g . a medium - sized sparrow , with long tail often held cocked . nominate race has head and nape brownish - grey , . . .
the reason ? it is quite difficult to tell the two species apart in the field ( read here for an excellent summary by peter pyle of some apparent differences in plumage ) . many contend that it is currently impossible to separate the two taxa in the field for a majority of individuals – and perhaps all of them . despair deepens due to the inclusion of the ‘mojave’ subspecies of sage sparrow ( a . b . canescens ) within bell’s sparrow and not with sagebrush . ‘mojave’ canescens are intermediate in appearance . plus , the canescens wintering distribution appears to overlap heavily with sagebrush in southeastern california , southern arizona , and northwest mexico .

as with many inconspicuous sparrows , the best way to find bell’s sparrows is to look for them in the early morning during the breeding season , when males perch out in the open on tall shrubs and sing for your attention . at other times they may be considerably harder to find . just be aware that in the right habitat—particularly in coastal sagebrush in southern california—these sparrows are fairly numerous . they tend to forage on the ground and scurry rather than fly between patches of shrub cover . patient watching and listening either for the sounds of foraging or for this bird’s bell - like tink call will help you find them .

the main reason for this post is that the lcrv is one of the few places were both species can occur . this can present a great opportunity to study each species , as well as for listing with the lcrv being one of the best places for bell’s sparrow in arizona , as well as sagebrush in california . within the lcrv , though , both taxa are reported to occur , but it is not known the exact status of each species . we have not seen many “sage” sparrows in the lcrv , but rosenberg et al 1991 reports that they have a preference for inkweed / iodine weed ( suaeda torreyana ) which is found in alkaline soils and is a localized habitat we do not visit very often . i know this winter though i will be spending more time in it !

formerly considered part of the same species as the sagebrush sparrow , this bird is locally common in sage scrub habitat near the california coast and locally in open habitats of the interior . it is often seen running about on the ground , with its longish tail cocked up above the level of its back ; when perched up on a shrub , it twitches its tail in a down - up motion like a phoebe .
we hope to have analysis of this month’s work completed by the summer of 2014 , and if additional proposals are successful , we are looking forward to adding more sites in arizona and along an east - west transect across southern california during the winter of 2014 - 2015 . if you are interested in volunteering in the field next season , we need you ! our volunteers enable us to increase capture rates and have made our project a success in arizona . please contact chris mccreedy .
given how new this split is and given the wide range of opinions as to how identifiable in the field the two taxa are , the following paragraph on identification should be considered tentative and in need of further evaluation . the papers used to split the two have cited morphological differences in the form of size , but little on plumage . one thing that is known is that both species molt before they reach the wintering grounds , so once present in the lcrv they should be at their freshest . below i will review some of the field marks i have seen mentioned . currently measurements are considered to be the most reliable way to identify the two species , i think however that the two are identifiable in the field though identification may be difficult especially when the two are worn in summer . the head / malar contrast of birds in the lcrv do seem to differ from those just east of there and some unscientific looking at photos online i am able to identify the majority of birds correctly . at this point i should note that of the field marks discussed below , patten and unitt 2002 only used measurements ( which they did find largely differed ) , mantle shade , and presence of back streaking . things like malar / head contrast were not evaluated . i should also mention that though hybridization appears to be rare ( hence why they were split ) my understanding is that it does occur .
head coloration may be useful , but i think how dark the head is can be difficult to judge and it is better to use the contrast between the head and the malar . i’ve also seen mention of the darkness of the auriculars , but this seems to be variable .
back streaking and mantle shade : both the amount and the boldness of streaking on the back may be useful , but there appears to be overlap , possibly only extremes may be identified using this field mark , or it may be useful in conjunction with other field marks . it may also be more useful when they are fresh as photos online of birds on the wintering grounds seem to have a more noticeable difference than photos from the breeding grounds . some fresh birds do seem to differ in mantle shade , but again it seems to be wear related and a lot of overlap .
primary projection maybe be useful as well , as the wing length measurements differ between the two . however this can be difficult to use in the field and needs further examination .
underpart streaking and coloration has been cited as a field mark , but this seems to be variable and i haven’t noticed any real difference looking at photos .
it may take a while to fully figure out the field marks of these two species , but i think we will come to a better understanding of identification . remember how impossible other splits were thought to be ( like cackling goose ) ? i don’t think this is going to be a “western” flycatcher type split , but one that with time we will come to better understand . course i could always be wrong only time will tell !

birder biologists currently living and working in the lower colorado river valley . when not out in the field i spend a lot of my time reading and writing about birds . i have always been drawn to areas under birded and species that we know little about .
david , thank you for a detailed post concerning this split . this will be a challenge at first , but as you pointed out , i think it will become easier to discern the differences over time , especially if a person gets out there and observes them as frequent as possible . thanks again !

as with various other species along california coast , may be vulnerable to loss of habitat . the endemic race on san clemente island , california , is endangered .
coastal sage scrub , chaparral ; in winter , also deserts . found year - round in unique sage scrub habitat on the california coastal slope and foothills . in the interior , also breeds in saltbush , chamise , and other low shrubs of arid flats . in winter some spread eastward into open flats and deserts with scattered brush .
forages mostly on the ground , picking up items from the soil or from plant stems , sometimes scratching with its feet . also does some feeding up in low bushes . when not nesting , may forage in small flocks .
3 - 4 , sometimes 2 - 5 . bluish white to pale blue , variably spotted or blotched with brown , gray , and black . incubation lasts about 13 - 16 days .
probably both parents feed the nestlings . young leave the nest about 9 - 11 days after hatching . often 2 broods per year , sometimes 3 .
mostly seeds and insects . feeds on many insects , especially in summer , including grasshoppers , beetles , true bugs , and others , also spiders . also eats many seeds of weeds , grasses , and shrubs . young are fed mostly insects .
male returns to same nesting territory each year , defends it by singing from a raised perch . nest site is usually in low shrub , less than 4 ' above the ground . sometimes placed on the ground under a shrub . nest is a bulky open cup , made of twigs , sticks , lined with fine dry grass , weeds , sometimes animal hair .
populations west of the sierra in california are mostly permanent residents . those from the interior are more migratory , with some spreading eastward into arizona in winter .

from a broader perspective , each of these species winter in a part of the continent that is projected to be much hotter and drier in the future due to climate change . they winter in arid scrub habitats that respond dramatically to rainfall – and to lack thereof . diminishing seed crops on their wintering grounds due to drought may decrease survival rates and individuals’ condition upon return to their breeding grounds .
given a lack of resolution in the species’ field identification , how can we survey birds to inform land managers and owners on how best to conserve these taxa ? point blue conservation science ( formerly prbo ) is currently in the field in southwestern arizona , hoping to shed as much light as possible on these identification , distribution , and habitat questions . with support from arizona field ornithologists and a cadre of amazing volunteers , we captured individuals at sites near phoenix , yuma , and lake havasu city during the first half of february 2014 . we took measurements on as many of the previously - noted potential differences in field marks and morphology as we could find in the literature and online , have added a few of our own , assessed the appearance of some of these features in different lighting conditions , at different distances and with different optics , and explored apparent differences in habitat preferences between the two species . dr . adrienne kovach ( university of new hampshire ) has offered her assistance to help us ground our captures’ field identification with confirmation of individuals’ sex and species via dna analysis .
previously considered conspecific with a . nevadensis . race canescens , very similar in appearance to a . nevadensis and possibly hybridizing with it where ranges meet , has been thought perhaps to represent a separate species ; alternatively , canescens may simply reunite present species and a . nevadensis ; research needed . race cinerea intergrades with nominate in nc baja california . race clementeae should perhaps be subsumed into nominate . four subspecies provisionally recognized .

formerly included in a broader emberizidae . recent phylogeny # r has recovered evidence of eight major clades within this newly recognized grouping : ( i ) melospiza and allies ; ( ii and iii ) melozone , atlapetes , pipilo and allies , which form two sister - clades ; ( iv ) zonotrichia , junco and allies ; and ( v–viii ) all other species , which form a polytomy at base of tree , but can be split into ( a ) arremon , ( b ) spizella , amphispiza , chondestes and calamospiza , ( c ) peucaea , arremonops , ammodramus and rhynchospiza , and finally ( d ) two genera that have often been placed in thraupidae , oreothraupis and chlorospingus .
until recently included in amphispiza , but molecular work indicates that these species are members of a well - resolved clade of “grassland” sparrows that includes pooecetes , oriturus , passerculus , melospiza and xenospiza , as well as several species formerly treated in ammodramus .
