the american carrion beetle ( necrophila americana , formerly silpha americana ) is a north american beetle of the family silphidae .

it lays its eggs in , and its larvae consume , raw flesh ( particularly that of dead animals ) and fungi .

the larvae and adults also consume fly larvae and the larvae of other carrion beetles that compete for the same food sources as its larvae .

nicrophorus americanus , also known as the american burying beetle or giant carrion beetle , is a critically endangered species of beetle endemic to north america . it belongs to the order coleoptera and the family silphidae . the carrion beetle in north america is carnivorous , feeds on carrion and requires carrion to breed . it is also one of the few species of beetle to exhibit parental care . the decline of the american burying beetle has been attributed to habitat loss , alteration , and degradation , and they now occur over less than 10 % of their historic range .
american burying beetles are the largest carrion - feeding insects in north america , growing up to 35 mm in length . most carrion beetles of the genus
unless you’re in the habit of examining carcasses , you may never come across a carrion beetle .
the american burying beetle is endangered statewide and nationally . restoration efforts are under way . this brightly patterned beetle specializes in cleaning carrion from the landscape , burying dead mice , birds , and other creatures .
the mites get rid of maggots and their eggs so there is more food for the carrion beetle .
american burying beetles are scavengers , attracted to decaying vegetation and carrion . adults feed on a wide range of species as carrion . they also consume live insects .

your carrion beetle must not exceed a certain size , or must be placed beneath the seat in front of you .
the american burying beetle is a carrion - feeding beetle of the family silphidae . the species is distinct and there are no proposed subspecies or species forms . it is one of the most striking beetle species in canada due to its large size and the brilliant orange markings on its otherwise black body .
habitat : considering the broad geographic range formerly occupied by the american burying beetle , it is unlikely that vegetation or soil type were historically limiting . today , the american burying beetle seems to be largely restricted to areas most undisturbed by human influence .
management research needs : identification and management information on the optimum carrion - producing vertebrates for the american burying beetle is needed . research on optimum carrion availability will provide information that is necessary for sampling , management and reintroduction efforts . population modeling information is needed .
status : the american burying beetle was listed as an endangered species in 1989 ( federal register 54 : 29652 - 29655 ) .
mites are known to frequently attach themselves to the american carrion beetle as it moves from one dead carcass to another . at each stop along the way , the mites drop from the beetle to also feed on the dead flesh . therefore , from a pest control standpoint , this type of beetle poses a dual challenge .

we captured it for later identification , and amanda ran it down . this is a carrion beetle . there are several species of carrion beetles , all in the family silphidae . there are over 20 , 000 species of beetle in north america . beetles are incredibly diverse . therefore , it did not surprise me to learn that there are several dozen species of carrion beetle in minnesota . this is probably in the genus
in the 1980s , entomologists documented the decreasing abundance of the american burying beetle across its range . collecting records indicate that east of the appalachian mountains the american burying beetle declined in a generally north to south direction , and the decline was well underway , if not complete , by 1923 .
common names : american carrion beetle - named for its primary carrion food source . american emphasizes that it is endemic to north america east of the rocky mountains . carrion comes from the latin word caro meaning flesh . burying beetle – a carrion - eating beetle so named because it buries the animal carcass for longer term consumption . scientific names : necrophila americana - the generic name if from the greek nekros , meaning
dead body
and philos , meaning
loving
in reference to its primary food source . the species name is a latinized form to reflect its american provenance . nicrophorus carolinus – the burying beetle genus is also a derivative of nekros as above with the addition of the greek phoros meaning ‘to carry . ’ the species name is reference to its first identification in the carolinas .
carrion beetles and maggots eat they same thing , so they compete with each other for food . but carrion beetles have a secret weapon they use to get rid of some of the maggots and get more food for themselves . carrion beetles carry tiny little mites on their backs . the mites travel with the beetle to a dead carcass , where they eat the eggs of maggots and the smallest maggots , creating more space and food for carrion beetles . some scientists think that the mites take care of carrion beetles by cleaning off bacteria the the beetle picks up from living on dead animals . below is a picture of a carrion beetle with mites on its back .
the carrion beetle pays a huge cost carrying the mites around wherever it goes , because they are heavy and affect its ability to move and fly . but otherwise , the mites do nothing … . they just hang on for the ride , waiting for the beetle to locate a dead mouse . then , when the beetle does located a dead mouse , the mites do not eat it . rather , they eat the maggots , the fly eggs , and larva of anything that is not a carrion beetle . they clean the carcass of the potential competitors of the carrion beetle’s larva .
as scavengers , american burying beetles play an important role in recycling decaying materials .

the adults’ voracious appetite for maggots certainly helps eliminate competition for their offspring . the carrion beetle larvae feed on the carcass , which would quickly be devoured by maggots without the intervention of the adult silphids . a few carrion beetle species feed on plants , or even more rarely , prey on snails or caterpillars .
the beetles themselves are black with a yellow shoulder area , although the coloring varies to a degree from northern to southern areas . the beetles can resemble bumble bees when they are in flight . by contrast , the larger american burying beetle features shiny black and orange - red coloration . also , the burying beetle is about 1 . 0 to 1 . 4 - in long , while the smaller american carrion beetle is 0 . 5 to 0 . 9 - in long .
populations of american burying beetles have been extirpated from 90 % of their original range .
the american burying beetle is the largest carrion beetle in north america ( 2 ) . it has extremely distinctive colouration , being shiny black with bright orange markings ; there are four orange bands on the wing cases ( known as ' elytra ' ) , but unusually the pronotum and face also have orange markings ( 2 ) .

the american burying beetle is the largest carrion - frequenting insect in north america ; it may reach a length of l l / 2 inches . like many other carrion beetles in the genus nicrophorus , it is shiny black and distinctively marked with two bright orange bands on each wing cover . unlike any other species , however , the pronotum ( the shield - like area just behind the head ) of the american burying beetle is also orange , and there is a small orange patch on the face between the eyes . while nebraska has 11 species of nicrophorus , only the american burying beetle has the orange pronotum , and it can be readily distinguished from the other , more common species .
specific habitat preference of american burying beetles is unknown . like many endangered species , this species seems largely confined to areas with the least human influence . american burying beetles thrive in areas with an abundance of carrion and have been found in grasslands , scrublands and forest edges .

carrion beetles and individuals of some species of mites can have a symbiotic relationship . each derives a benefit from the other . the mites climb aboard the carrion beetle to be transported to new food supplies they could never reach by foot . the mites in turn eat the eggs and freshly hatched maggots of flies that compete with beetle larvae for the food source . therefore , a mite - laden beetle is more likely to have offspring that survive .

the american burying beetle , ( nicrophorus americanus ) oliver is a member of the carrion beetle family silphidae . carrion beetles , as their name implies , are an important part of a vast host of scavengers that are responsible for recycling decaying materials back into the ecosystem . they are also referred to as burying beetles or sexton beetles . there are 570 species of silphids found worldwide , and 31 of them occur in north america . there are 18 species in nebraska .

historical records offer little insight into what type of habitat was preferred by the american burying beetle . current information suggests that this species is a habitat generalist , or one that lives in many types of habitat , with a slight preference for grasslands and open understory oak hickory forests . however , the beetles are carrion specialists in that they need carrion the size of a dove or a chipmunk in order to reproduce . carrion availability may be the greatest factor determining where the species can survive .
a scene from stephen king ' s latest novel ? not at all . the creatures are carrion beetles , also commonly known as burying beetles , and they are on of nature ' s most efficient and fascinating recyclers . but , like several other insect species , these beetles are nearing extinction . the american burying beetle , the largest of the north american carrion beetles , has so drastically declined in numbers and range that , in july 1989 , it was added to the federal endangered species list .
biologists have not unlocked the mystery why the american burying beetle has disappeared from so many areas . widespread use of pesticides may have caused local populations to disappear . the dramatic disappearance of this insect from many areas , however , took place before widespread use of ddt . lack of small carcasses to bury would prevent the species from reproducing , and changes in land use has reduced the quantity of small - to medium - sized birds and mammals preferred by the american burying beetle . even the extinction of the once ubiquitous passenger pigeon may have had a ripple effect on carrion feeders like this beetle .

as i learnt just two days ago ( from a carrion beetle that was also crawling with mites ) , they don’t just eat dead mice and such but are also very fond of cat food .
the american burying beetle has been recorded historically from at least 150 counties in 35 states in the eastern and central united states , as well as along the southern fringes of ontario , quebec and nova scotia in canada . collecting records indicate that east of the appalachian mountains the american burying beetle declined in a generally north to south direction , and the decline was well underway , if not complete . by 1923 .
carrion beetles come in many sizes . some are very small while others can get as big as 1 . 4 inches ( or about 35 mm ) . the average size of a carrion beetle is 1 / 2 inch . they have flat , flexible bodies that allow them to crawl under dead animals .
the earliest record for the american burying beetle in nebraska is 1921 , although it undoubtedly occurred here before that time . they were again collected in 1957 and have been sporadically recorded since that time . the westernmost north american record for the american burying beetle is near north platte , nebraska . the most recent sightings ( 1992 - 1997 ) are from lincoln , dawson and cherry counties . the available information suggests that this species occurs rarely and locally , primarily in undisturbed areas in the eastern two - thirds of the state .

about an inch and a half long , the american burying beetle can be identified by its striking , distinctive coloring . the body is shiny black , and on its wing covers are four scalloped , orange - red markings . most distinctively , there is an orange - red marking on the beetle ' s pronotum , a large shield - like area just behind the head . the american burying beetle has orange facial markings and orange tips on the antennae . the beetles are strong fliers , moving as far as a kilometer in one night .
the american burying beetle is protected under the federal species at risk act ( sara ) . more information about sara , including how it protects individual species , is available in the species at risk act : a guide .

the american carrion beetle is also known by its scientific name , necrophilia americana . it gets its name from the prominent role that the flesh of dead animals plays in its existence . for example , it lays its eggs in or around carrion , and the larvae that emerge then feed on the animal remains . the beetles are also known to feed on fungi and rotting fruit . this article will discuss where these beetles live , what they look like and their life cycle .
the decline of the american burying beetle is probably the result of an interplay of several complex factors that include ( 1 ) artificial lighting that decreases populations of insects active at night , ( 2 ) changing sources of carrion because of habitat alteration , ( 3 ) isolation of preferred habitat because of land use changes , ( 4 ) increased edge effect harboring more vertebrate competitors for carrion and ( 5 ) the possibility of reduced reproduction because of some genetic characteristic of the species .
considering the broad geographic range formerly occupied by the american burying beetle , it is unlikely that vegetation or soil type were historically limiting . today , the american burying beetle seems to be largely restricted to areas most undisturbed by human influence . in nebraska , the sandhills is just such an area , and it is there that the beetles have been recently rediscovered . gothenburg , brady , north platte and the valentine national wildlife refuge are all locales in which beetles are now found .

the larvae spend about a week feeding off the carcass then crawl into the soil to pupate , or develop . mature american burying beetles emerge from the soil 45 to 60 days after their parents initially bury the carcass . adult american burying beetles live for only 12 months .
some species will fly to porch lights on summer evenings , so you may get lucky and find one on your front door . while we might find the carrion beetle’s diet rather distasteful , these scavengers provide a vital ecological service - disposing of carcasses .

in the ecological sense , carrion beetles don ' t like flies , mostly because fly maggots compete directly with beetle larvae . as a way to diminish competition , adult carrion beetles begin consuming maggots as soon as the fly larvae hatch . this allows a window of opportunity in which carrion beetles can mate and lay their own eggs before fly maggots have consumed the carcass completely . unfortunately for the beetles , flies just keep on coming and laying eggs , so it ' s almost impossible to eat all the maggots that result . it would be great for carrion beetles if they had assistance in keeping flies at bay and , in fact , they do !

carrion beetles face a special problem that we see here and there in the world of animals , and when it occurs there is often an interesting adaptive result . ( this is how we know adaptation is a real thing and the diversity we see in nature is often the result of adaptatoin . ) carrion beetles lay their eggs in or on the body of dead mammals or birds . but dead mammals and birds are somewhat rare , especially the relatively undisturbed ones , the ones that are not about to be digested by something . therefore , a carrion beetle that has a trait that maximizes the use of this rare resource will have a selective advantage over carrion beetles that don’t .
american burying beetles have been lost from the majority of their former range ; populations in the east had largely disappeared by the 1920s , whilst the decline in the american midwest was well documented in the 1980s ( 2 ) . one of the major causes of this decline in abundance is the fragmentation of available habitat ; leading to changes in the availability of carrion , increased competition , and the isolation of remaining popualtions ( 2 ) .

carrion beetles are a family of beetles that feed on the bodies of dead and decaying animals . when an animal dies in the woods , it immediately begins to decompose or rot . carrion beetles eat the rotting flesh of dead animals so they are a very important kind of beneficial bug called
decomposers
. if you remember the meaning of two different words , you will remember why this beetle is a beneficial bug .
carrion beetles have many different weapons that they use to protect themselves against attack by other predators . their defense systems also allow them to live comfortably and grow in different kinds of environments . many carrion beetles blend into their environment and can not be seen easily because they are dark black and brown in color . however , there are other carrion beetles that have bright colors like orange , yellow or red . this bright coloring warns predators to keep away . animals with bright colors can be poisonous , so the bright colors of some carrion beetles make predators think they are poisonous .
a matter of taste – the natural history of carrion beetles , by brett c . ratcliffe , curator of insects , university of nebraska state museum
american carrion beetles are found in most areas of the united states that are east of the rocky mountains . they more commonly reside in moist environments , and they will be more active on warmer days . as the beetles fly about , their sense of smell alerts them to the presence of dead animals .
carrion beetles are found all over the world . there are 46 different kinds in north america , many of which are found in the united states .
preserve selection and design considerations : preserves must contain a continued abundance of food sources for these beetles . carrion must be between 50 and 200 grams .
in 1983 the american burying beetle was included as an endangered species in the invertebrate red book published by the intemational union for the conservation of nature . in the united states , it was proposed as an endangered species in 1988 and was placed on the state and federal endangered species lists in august 1989
specifically it is the largest native species , american burying beetle ( nicrophorus americanus ) , that is now extirpated throughout most of eastern north america . they prefer chipmunk - sized carcasses , and the elimination of passenger pigeons as an abundant food source is one of several hypotheses proposed to explain their decline .
american burying beetles were listed as an endangered species by u . s . fish and wildlife service in 1989 . they are currently considered critically endangered by the iucn and are likely extirpated from michigan . habitat fragmentation and habitat loss are largely held responsible for the decline of this species . habitat fragmentation and deforestation has reduced populations of species that become carrion in which this species broods . increased competition with other scavengers has also contributed to the population decline of american burying beetles .
american burying beetles are scavengers . adults hunt for decaying carcasses , which are either used as a source of food or are buried for future use by larvae .
much has been done to understand the life history of the american burying beetle and promote its recovery . a recovery plan was prepared by the u . s . fish and wildlife service . the plight of the american burying beetle was publicized . factors responsible for the decline were investigated . information was solicited on all collection records . studies of reproductive ecology and population status were conducted . surveys of historical collection localities were carried out . captive breeding populations were established . captive - raised beetles were reintroduced to a historic site at penikese island , massachusetts . the population there is being monitored and added to as necessary .
the family silphidae is a fairly small beetle group , with just 175 species known worldwide . of these , about 30 species inhabit north america .
management requirements : because the american burying beetle has a highly vulnerable status in the wild , the two known natural populations ( block island , rhode island and eastern oklahoma ) should be protected and maintained . another requirement is maintaining captive populations for reintroducing the beetle to its historical habitat . maintaining proper habitat ( mature forests ) , and enhancing new habitat is very important . enhancing new habitat and open fields can be done by mowing , grazing and burning .
american burying beetles typical live 1 year . newly emerged adults remain in the soil during the winter season and mate in the summer . adults die after raising their offspring .

nature is so valuable to the prospective parents that they bury it to keep it from being stolen .
other theories for the decline exist . ddt was unlikely responsible , for the decline had occurred 25 years before ddt was used . a species specific disease is unlikely , though not impossible . populations of other carrion beetle species have remained largely intact . american burying beetles appear to have broad habitat tolerances , so direct habitat loss was unlikely responsible initially . once populations of burying beetles become isolated , though , habitat loss can become an important factor . movements between habitats occurs less frequently . genetic variation suffers . interspecific competition at the genus level also comes into play once a species is geographically isolated .
historical records show that this beetle once lived in 35 states , the district of columbia , and three canadian provinces . now , natural populations are known to occur in only four states : rhode island , oklahoma , arkansas , and nebraska . biologists are not sure what led to the disappearance of this insect from so many areas and are attempting to determine the reasons for its decline . as part of this ongoing research , and in an attempt to establish another beetle population , biologists have released laboratory - raised american burying beetles on penikese island in massachusetts , historical habitat of the animal .
several groups of beetles eat carrion . those in the carrion beetle family are flattened , usually black , often with markings of red , orange , or yellow . the shell - like forewings ( elytra ) have a distinctive shape , wider toward the end of the body and narrower toward the front . in many species , the elytra are too short to cover the final 1 to 3 segments of the abdomen tip . the antennae are distinctively clubbed , often with minute hairs or colors at the very tip . these beetles often secrete or spray foul - smelling substances , or just plain smell bad themselves .
the bright bands of red or orange on the wings of many carrion beetles warn potential predators that they won’t make a very delicious meal , so don’t bother tasting them . there’s something to be said for the old adage “you are what you eat . ” carrion beetles , after all , feed on rotting flesh , and all the bacteria that goes along with it . silphids apparently taste and smell like death .
the famous entomologist j . henri fabre wrote that carrion beetles make “a clearance of death on behalf of life . ” when we overcome our revulsion , we , too , can appreciate these interesting little grave diggers .
the emerging beetle larvae will feed on both the raw flesh and the other larvae within it . the adult beetles will often consume other feeding insects to eliminate competition for food . this makes it easier for the beetle larvae to adequately feed and survive . the larvae eventually burrow into the surrounding soil where they spend the winter . they emerge from their pupal stage the next spring , and they mature into adult beetles .
my favorite spotting of one of these beetles was floating in a swimming pool . the beetle was not moving anymore and the mites were huddled away from the slowly encroaching water . it was “titanic” in miniature .

in addition to the known populations in rhode island and oklahoma , american burying beetles were collected in ontario , kentucky , arkansas , missouri and nebraska as late as 1970 . if the species still exists in these areas , it is very localized .
the specific habitat requirements of this species are not fully understood and it appears that the availability of carrion may be the limiting factor . in nebraska , beetles have been observed in grassland prairie , scrubland and forest edges ( 2 ) .

though carrion beetles as a family range in size from just a few millimeters to as long as 35 mm , most species we commonly encounter top 10 mm in length . silphids have clubbed antennae , and tarsi ( feet ) with 5 joints .
carrion beetles also have chemical defenses . they secrete a strong , smelly odor that irritates other bugs and small animals . they can even spray the odor at predators to keep them away . they move the end of their abdomen around and spray in all directions .
the larvae spend about a week feeding off the carcass then crawl into the soil to pupate , or develop . mature n . americanus beetles emerge from the soil 45 to 60 days after their parents initially bury the carcass . adult american burying beetles live for only 12 months .
rotting vegetation and dead animals may not sound good to you , but this insect finds it all pretty tasty . nature ' s leftovers are its bread and butter ! this distinctive beetle is found on a variety of dead animals including mammals , fishes , snakes and frogs . breaking down all of this garbage into useful soil nutrients is a dirty job , but carrion beetles are good at it . their life cycle is so well known that forensic investigators use them to investigate the time of death of human remains .

. . . carrion is rather ephemeral and unpredictable food source therefore species have to be able to locate it quickly and at the right moment ( dekeirsschieter et al . , 2011 ) . this is crucial especially in severe competition of other necrophagous species . . . .
after burial , the beetles strip away fur or feathers and work the mass into a compact ball . they will then
inoculate
the remains with secretions that preserve the carrion and modify the course of decomposition . the female constructs a short chamber above the carrion in which she lays from 10 to 30 eggs . returning to the carcass , she prepares a conical depression on top of it . both parents regurgitate droplets of partly digested food into the depression . the fluid accumulates as food for the larvae that hatch in a few days .
. . . one domain is that of forensic entomology , applying the study of insects and other arthropods to criminal investigation . so far , only recently more extensive research on forensic application of beetle data has started ( dekeirsschieter et al . , 2011b ; matuszewski , 2012 , matuszewski et al . , 2008matuszewski & szafałowicz , 2013 ) . carrion ( whether human or animal ) is often referred to as a functional ecosystem ( barton et al . , 2013 ; villet , 2011 ; colijn , 2014 ) . . . .
carrion beetles and other decomposers are important because they get rid of dead matter by eating it and breaking it down into smaller pieces that can be placed back into the ecosystem . the small pieces of dead animals become nutrients that other animals and plants can feed on . some kinds of carrion beetles actually bury small animal carcasses so that they can lay their eggs on it ( the eggs will be safer under the ground ) . when carcasses are buried , they decompose faster and don ' t smell as much - helping to keep our environment cleaner .
an impressive example of adaptive behaviour and the complexity of relationships between species . when i first saw the picture , i thought the mites were simply parasiting the beetle , but the truth turns out to be far less simple and more fascinating . thanks for sharing !

although this species historically ranged from southern maine to south dakota and south to texas and florida ( temperate eastern north america ) , and was widely distributed within its range , the american burying beetle is currently known to exist in only two locations . one population is on block island , rhode island . the other is a recently discovered population in eastern oklahoma . habitats occupied on block island include maritime shrub thickets and grazed fields ( coastal moraine grasslands ) . oklahoma sites are representative of the forest / pasture ecotone and open pastures in a ridge and valley area of that state .

when a dead person is found , forensic scientists analyze the age and life cycle stages of carrion beetles present and thus can determine an approximate time of death — which helps solve crimes . also , by competing with fly maggots , burying beetles help control the numbers of flies that annoy people .
this is known as the life / lunch dichotomy . in the competition for the use of the meaty carcass of a dead mouse , if the fly loses out it gives up the equivalent of lunch … there are still other opportunities , in this case , poop , for it’s young to eat . the carrion beetle , however , may be giving up its life ( or the life of its offspring , really ) because mouse carcasses are very rare , so if the one carcass it manages to locate is eaten up by fly maggots , it’s offspring will not survive .
n . americanus is between 25 and 45 mm long and can be identified by its striking , distinctive coloring . the body is shiny black , and on its wing covers are four scalloped , orange - red markings . most distinctively , there is an orange - red marking on the beetle ' s pronotum , a large shield - like area just behind the head . n . americanus has orange facial markings and orange tips on their large antennae . the beetle is nocturnal and is a strong flier , moving as far as a kilometer in one night .
while the relationship between beetle and mites is not as black and white as described it is interesting to see evolutionary principles applied to this detail of nicrophorus behavior . of course , the beetle’s efforts to secure the rare resource for its offspring go much further – when the pair prepares the carcass for burial they reshape it and may well get rid of or destroy other eggs / larvae . they also stay underground and feed their young larvae – overall a level of involvement that’s rare in beetles and understandable under the premises that you describe in your third paragraph .


the yellow-winged pytilia ( pytilia hypogrammica ) , also known as the red-faced pytilia , is an african estrildid finch .

it has an estimated global extent of occurrence of 250,000 km ² .

it is commonly found in benin , burkina faso , cameroon , central african republic , chad , the democratic republic of the congo , côte d'ivoire , ghana , guinea , liberia , nigeria , sierra leone and togo .

yellow - winged pytilia

scientific name : pytilia phoenicoptera = red winged . pytilia hypogrammica = yellow winged pytilia .
common name / s : aurora finch , aurora waxbill , crimson winged pytilia , red faced pytilia , red winged pytilia , yellow winged pytilia .
status in ( australian ) captivity : red winged = secure . red faced and yellow winged are harder to find .

the yellow - winged pytilia ( pytilia hypogrammica ) , also known as the red - faced pytilia , is an african estrildid finch . it has an estimated global extent of occurrence of 250 , 000 km 2 .
strike three in formulating my tree of pytilia genetics was / is the continuing debate as to the notion of the ‘split’ red - winged pytilia . some say that if a red - winged pytilia has one yellow parent it must be a split – in other words even though it looks like a red - winged pytilia it carries the gene for yellow wing colour in its genetic make up and if two such splits are mated together then it is possible to obtain yellow winged offspring .
the basics : the yellow - winged pytilia is a dashing african waxbill that shares a very close relationship ( and sometimes the name aurora finch ) with the red - winged pytilia . the rather rare yellow - wing is found in mostly open country in western central africa .
i have had no experience in keeping the yellow - winged pytilia , a colour variation of the red - faced pytilia , which is difficult to obtain and is kept by a few breeders , predominantly in victoria and tasmania . the red - faced pytilia is the dominant species , so let us hope that the dedicated few who are lucky enough to own the yellow - winged pytilia will have much success in keeping them .
cost ( victoria ) per pair : - red faced ( approx . ) $ 250 . red winged approx . $ 100 . yellow winged approx . $ 500 .
green - winged pytilia - pytilia melba - this common species of finch belongs to the family estrididae . it is found throughout most of sub - saharan af… | pinteres…
appearance : the adult male yellow - winged pytilia is much like the red - winged pytilia , a bird with a gray background color that possesses barred underparts and a red rump . however , his primary feathers are yellow instead of red , and he has a bright red face and a black tail . the female lacks the red face and is overall somewhat duller .
in australia , the melba finch pytilia melba and the aurora finch pytilia phoenicoptera are extremely popular and have been kept with good breeding results , for decades . in recent years , there has been increased interest in the red - faced pytilia pytilia hypogrammica and its very close look - alike , the yellow - winged red - faced pytilia , which is a colour variation with the same scientific name . it is not a subspecies .
breeders can have a struggle setting up pairs . it ' s a tough call to distinguish the yellow - winged pytilia female from its cousin , the red - winged pytilia . the birds may agree about that , since the two species apparently hybridize where they overlap in the wild . in captivity , you might sometimes encounter a red - faced , red - winged pytilia which turns out to be a yellow - winged pytilia with a bit of red - wing in its background . the red wing color is dominant over the yellow . australian breeders in particular have noted that they may have trouble finding pure - bred examples of either of these two species . fortunately , the hybrid is beautiful and requires the same care .
behavior / temperament : the yellow - winged pytilia is held in high regard by serious aviculturists as a peaceful aviary bird but the pure form may have been somewhat forgotten in the rush to create the more colorful red - faced red - winged pytilia hybrid . the nickname red - faced aurora adds to the confusion as well . this species does not like humans disturbing or checking their nest .
housing : yellow - winged pytilias will show beautifully in a large planted aviary , but you must monitor the situation to make sure that there is enough cover and nest sites for all the birds to nest safely without conflict . you should not allow them to share quarters with melba finches or other pytilias , because they will hybridize . an additional issue is that the feisty male melba finch may attack other red - faced birds , including his cousin , the yellow - winged pytilia .

the red - winged and yellow - winged pytilias are very similar in appearance with the males of both ‘types’ having the distinctive red head and , as the name suggests , with one having red wings and the other yellow . i once read somewhere that the husbandry for all three was very similar but it has been our experience that the aurora is the far easier species to propagate than either of the other ‘types’ .
basic seed mix should include canary seed , white french millet , japanese millet , and yellow and red panicum .
the family of finches called pytilia are a colourful and popular group of finches that are always in demand by australian and overseas aviculturists alike .
the red - faced pytilia ( pytilia hypogrammica ) is a beautiful species that has gained popularity in recent years . it is very similar in nature to the aurora finch , although the plumage is more colourful . as the cock becomes older , the colourful plumage intensifies . the hen is slightly darker in colour than the aurora finch hen .
maybe , just maybe , this all came about because of the infusion of aurora blood that went into both the red & yellow - winged forms throughout their journey in our aviaries . every honest pytilia keeper will cite an example of where they purchased a pair of red - wing pytilas only to find they had a red - wing cock and a
hen
normal aurora male ! ! i even know of one person who used to cull these
grey headed hybrids
until i assured him that they were normal auroras and not some new hybrid at all .
fast forward a few months and he rang me back and said he had just had a ‘hen’ yellow - wing dna sexed and it confirmed that the bird was a cock – yes , a yellow - wing cock with no red head at all ! ! following that a few people i knew started to report similar ‘occurrences’ within their flocks . turned out that these startling throwback hens were in fact startling throwback cocks ! !
some breeders have enjoyed success in large cages that give the birds room to fly , court , and exercise , without coming into contact with competitors . a good size for each pair would be 36” wide by 24” deep by 18” tall . have barriers between the cages so that the pairs can hear but not see each other . all pytilias are sensitive to cold and damp , so your aviary yellow - winged pytilias will need access to warm , dry winter quarters .
however , you cannot ultimately expect much success with yellow - winged pytilias unless you provide a good supply of live insects . variety may be important , and you may wish to construct a home trap for collecting small moths , beetles , and so on , as well as providing the standard small commercial insects like mealworms and waxworms . in the wild , they prefer termites , and some australian breeders have experimented with supplying termites , but most homeowners won ' t be willing to risk it .
now when we first reached the top of a breeder’s sale list and were able to obtain 2 pairs of both yellow & red - wings there were a few differences that appear to have disappeared from the present day birds available in australia .
some unscrupulous breeders may attempt to pass off an aurora finch hen for a red - faced pytilia hen , so be aware of this and buy only from reputable breeders . the husbandry of this species is identical to that of the aurora finch .
some say this is set in concrete other say it is not . unfortunately i cannot contribute to this debate suffice to say that when i once had a cock yellow - wing and a hen red - wing breed in a holding aviary all six youngsters had red wings .

diet : the pytilias have thinner beaks and larger bodies than the other waxbills , reflecting the fact that they crack fewer seeds and devour more insects . true , the backbone of the diet is a high quality small seed mix , fresh enough to sprout – and you should test it by sprouting regularly . the yellow - winged pytilias love the milky seeding heads of grasses , in addition to the sprouts . . you should also supply a finely chopped salad that includes greens , apple , carrot , and broccoli , as well as eggfood and / or a high quality finch pellet that the birds will eat .
how do i know ? well , i also received one of these birds - supposedly a hen pytilia but in reality a cock aurora – and when paired to a normal hen aurora produced me a couple of nests of normal healthy auroras . not a red head feather on any of them i hasten to add ! !
health wise they have a reputation for suddenly ‘fluffing up’ with very few fully recovering . if you have them autopsied the usual cause of death comes back as liver damage but we have yet been able to pin - point the causes of this . droppings show the usual signs of malabsorption and tend to be a cheesy yellow colour and very large .

the melba finch ( pytilia melba ) is considered the most colourful of this group and as such is the most popular . this particular species always catches the eye of beginners and experienced breeders alike . in recent years there has been a very high demand for these finches . however , as the numbers available to meet this demand are low , there has been a fairly sharp increase in this bird’s retail price .
the most obvious was the colour of the hens – these were vivid grey much akin to the cock aurora and nothing at all like the dour hen aurora . the hens also had fine stippling of black lines through the chest feathers and were striking in their own right . this is no longer the case with many hen red & yellow - wings resembling hen auroras and it is a rarity to see the dark coloured hens .
the pytilia species discussed have similar housing and feeding requirements . i feed a basic commercial finch mix during the non - breeding season . as the breeding season commences i add niger seed , maw , linseed and black and white lettuce seed . i also introduce a dry egg and biscuit mix along with plan madeira cake . the birds show more interest in grit , when they start nesting . during this period i substitute the basic small plain grit for a mix containing charcoal , canundra shell and baked crushed fowl eggshells .
due to their less colourful plumage the aurora finch ( pytilia phoenicoptera ) is not as popular as the melba finch . however , in my experience , this species is easier to breed and keep than the melba finch and is not as aggressive or as intimidating . their reliance on livefood is high but not as high as that of the melba finch . they tend not to be as tight sitters as melba finches so nest inspections or disturbance should be avoided . as these birds like thick , well - protected nest sites , plenty of tea - tree branches lining the aviary shelter is a definite asset .
of the pytilia family , the melba finch is the most heavily reliant on livefood . they will abandon chicks if a good supply of livefood is not continuously supplied . this reliance on livefood has seen a geographical trend , as to where this bird is more popularly kept . in the past , larger inner city areas have not been recognised as a stronghold for this bird . this species was bred in areas with large population of termites . in new south wales the species has been bred in numbers in the hunter valley and the southern highlands , where there are plenty of termites . in recent years , breeders from non - traditional areas are having success by offering the birds bush fly maggots instead of termites .
so if you are looking for the ultimate finch breeding challenge you could do worse than consider tackling the pytilia family . a large group of australian breeders worked tirelessly to ensure that we would have all three species remaining in our aviaries for years to come so the rest of us mere mortals owe it to them to preserve their
legacy
! before purchasing these species try and gain as much information from breeders as possible and be prepared for some heartbreak along the way , but stick to it as these are one of the most stunning finches available to us . if after several attempts you have not managed to ‘crack’ this species you can always join us at finch keepers anonymous where you can announce yourself with
hi , my name is…… . . and i’ve been keeping pytilis for too long ! ! !
we’ll all understand ! ! !

estrildid finches are distributed throughout africa , south asia , australia and neighbouring islands in the indian and pacific oceans . some specific phylogenetic and systematic debated questions have been clarified in the present study by mitochondrial cytochrome b dna sequencing of 61 species of estrildids and subsequent analyses of results by both bayesian inference and maximum likelihood methodologies . our results support that estrildids are a monophyletic group with polytomies that may have started evolving by middle miocene epoch ( about 16 , 5 million years ago ) . this proposed timing is coincidental with the fringillinae finches’ radiation starting time and also with the biggest hymalayan and tibetan plateau uplift , triggered by the indian tectonic plate strongest collision ; this established present day southern asia monsoon regime and other drastic climatic changes , like a dryer weather in tibetan plateau and china deserts . the estrildid finches form a monophyletic group which includes several polytomies and comprises african , asian and australian birds . the most ancient evolutive group comprises african ( african silverbill ) , asian ( indian silverbill ) and australian ( diamond firetail ) ; this suggests that the whole estrildids radiation might have originated around india . more estrildid species will be studied in order to further establish this group phylogeography . in addition , monophyletic radiations include species from different continents . finally , ploceinae genus quelea finches is a group separate and basal from estrildini and viduini species in our dendrograms .
open access will revolutionize 21 st century knowledge work and accelerate the diffusion of ideas and evidence that support just in time learning and the evolution of thinking in a number of disciplines .
it is important that students and researchers from all over the world can have easy access to relevant , high - standard and timely scientific information . this is exactly what open access journals provide and this is the reason why i support this endeavor .
publishing research articles is the key for future scientific progress . open access publishing is therefore of utmost importance for wider dissemination of information , and will help serving the best interest of the scientific community .
open access journals are a novel concept in the medical literature . they offer accessible information to a wide variety of individuals , including physicians , medical students , clinical investigators , and the general public . they are an outstanding source of medical and scientific information .
open access journals are extremely useful for graduate students , investigators and all other interested persons to read important scientific articles and subscribe scientific journals . indeed , the research articles span a wide range of area and of high quality . this is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals .
open access journals represent a major break - through in publishing . they provide easy access to the latest research on a wide variety of issues . relevant and timely articles are made available in a fraction of the time taken by more conventional publishers . articles are of uniformly high quality and written by the world ' s leading authorities .
open access journals have transformed the way scientific data is published and disseminated : particularly , whilst ensuring a high quality standard and transparency in the editorial process , they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets .
not only do open access journals greatly improve the access to high quality information for scientists in the developing world , it also provides extra exposure for our papers .
open access ' chemistry ' journals allow the dissemination of knowledge at your finger tips without paying for the scientific content .
in principle , all scientific journals should have open access , as should be science itself . open access journals are very helpful for students , researchers and the general public including people from institutions which do not have library or cannot afford to subscribe scientific journals . the articles are high standard and cover a wide area .
the widest possible diffusion of information is critical for the advancement of science . in this perspective , open access journals are instrumental in fostering researches and achievements .
open access journals are very useful for all scientists as they can have quick information in the different fields of science .
there are many scientists who can not afford the rather expensive subscriptions to scientific journals . open access journals offer a good alternative for free access to good quality scientific information .
open access journals have become a fundamental tool for students , researchers , patients and the general public . many people from institutions which do not have library or cannot afford to subscribe scientific journals benefit of them on a daily basis . the articles are among the best and cover most scientific areas .
these journals provide researchers with a platform for rapid , open access scientific communication . the articles are of high quality and broad scope .
open access journals are probably one of the most important contributions to promote and diffuse science worldwide .
open access journals make up a new and rather revolutionary way to scientific publication . this option opens several quite interesting possibilities to disseminate openly and freely new knowledge and even to facilitate interpersonal communication among scientists .
open access journals are freely available online throughout the world , for you to read , download , copy , distribute , and use . the articles published in the open access journals are high quality and cover a wide range of fields .
open access journals offer an innovative and efficient way of publication for academics and professionals in a wide range of disciplines . the papers published are of high quality after rigorous peer review and they are indexed in : major international databases . i read open access journals to keep abreast of the recent development in my field of study .
it is a modern trend for publishers to establish open access journals . researchers , faculty members , and students will be greatly benefited by the new journals of bentham science publishers ltd . in this category .

justification : this species has a very 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 has not been quantified , but it is not believed to 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 .
the global population size has not been quantified , but the species is described as scarce and little known ( clement 1999 ) . trend justification : the population is suspected to be stable in the absence of evidence for any declines or substantial threats .

these birds are beautiful and sweet , and while very friendly , unlike most finches they are not easily handled , but make for great viewing and companionship . their chirps are lovely . these birds prefer the company of many of their peers , so dont keep just one ! i love finches for their sweet quality . these birds will build their own nest in the brush or will use a finch nest box but do like a small plant pot with an open end attached to the wall , so make sure you give them a space to cuddle ! .
to those with a scientific bent is a denizen of sierra leone , north - east guinea through to cameroon in africa .
the aurora or p . phoenicoptera is a common exotic finch species which is a free breeder and has a charming quiet disposition in the aviary .
similar to the blue - cap i believe the frequency of live food delivery is a key factor with this species . they eat both smaller & mini mealworms and maggots with relish but , naturally , favour termites ( white ants ) when feeding young . in case you do not feed termites relax as we have bred them here in tasmania without them as have a number of english aviculturists that ian spoke to .
they seem ambivalent to green food and soaked / sprouted seed in my aviaries but a mate tells me his birds love the lowe - type blended vegetable mix he feeds – yet our initial stock came from the same source ! ! they also love the african waxbill mix we feed as outlined in an earlier edition of australian birdkeeper – in fact blue - caps . orange cheeks and pytilias seem to be drawn to this mix .
a general finch mix is fed – we use elenbee seeds clifton finch mix – supplemented with a little extra red panicum .
i have also seen them build behind seed hoppers , bowls and small cages in their aviary – unfortunately eggs can be and regularly are lost if the nest is not supportive enough ! i favour the medium sized cane wicker baskets feely available in good pet outlets . white medium sized emu feathers are favoured to line the nest while swamp / november / blown grass is a firm favourite for the nest proper . if made solely from this grass the nest has a propensity to be brittle and non - supportive so watch that eggs do not fall through !
pairs are variable as to nest inspection so know your birds well before checking nests . young pairs seem to be infertile for their first few nests so it is not such a bad idea to inspect nests to avoid them spending days sitting on clear eggs or even laying fresh eggs amid old , rotten ones !
in keeping with the aurora they are a placid species and we do not recommend keeping them in with the more boisterous finches as they tend to be dominated by such species . in my specialist flights i keep them with a pair of blue - capped waxbills in a 3x1m flight .
chicks are black and easily identified if found jettisoned on the floor . i have had some success rearing difficult finches under the
new
javan munias but they have baulked at rearing pytilias so far !
as a general rule of
finchkeepers thumb
we recommend a 3 monthly worming regime supplemented with coccidian control medication at least 3 times a year or even concurrently with your worming program – depending upon your climatic conditions .

as an aviary species , the melba finch can be aggressive in mixed collections . one of my hens killed three cocks in succession until i caught her in the act . this species can be overzealous when protecting their nests .
these birds require an enclosed aviary where they can seek shelter from bad weather . long periods of wet weather are not good for this species and they will succumb if adequate shelter is not provided .
in australia , the melba finch and the aurora finch are extremely popular and have been kept with good breeding results , for decades .
during the breeding season , livefood is increased and is essential . termites are excellent and have been the most widely used . as termites are becoming harder to obtain , i now supply bush fly maggots with great success . all my birds take these without hesitation . to provide dietary variety i also feed mealworms . some breeders have had success using fruit fly and crickets .
greenfoods in the form of summer grass , winter grass , chickweed and seeding millets are also consumed . these species are not as reliant on greenfood as our native finch species , however they will consume a reasonable amount .
these species will breed in very dense cover and show no preference for live shrubs over tea - tree branches . my birds have bred in both nest boxes , tins and gourds and sometimes build their own nests . nests are lined with feathers , coconut fibre and finer grasses such as november grass .
nest disturbances or inspections must not be undertaken as the finches will toss young out easily . once they breed they can produce nests in quick succession . it is wise to house only compatible pairs in the breeding aviary , and previous young should be removed , as unmated adults or previous young are inquisitive and can cause disturbances to nesting pairs .
the clutch size is usually 4 - 6 eggs with a reasonably high fertility rate of 70 - 75 % . incubation lasts for approximately 13 days with fledglings leaving the nest three weeks later .
as with many species , chicks will often leave the nest early and are difficult to return to the nest . in warm weather i place a good quantity of soft grass on the shelter floor , which in my set - up is separate from the flights and the chicks snuggle up in this for a few days until they fly . in cold weather i put them in a carry box overnight and return them to the aviary the next morning .
if these birds are provided with good quality food and well - sheltered aviaries they will thrive and produce many healthy chicks . they are a long - lived and hardy species that deserve a place in your aviary .

the aurora finch likes a planted aviary . the aurora finch likes to forage on the ground so care must be taken to ensure the floor of the aviary or cage is kept clean . mating and courtship may take place at ground level so it is preferable to have an open area on the floor of the aviary . the open area on the floor is often covered with a layer of dry sand .
they can be bred in a canary style breeder cage of about 900mm long x 400mm high x 400mm deep ( 36 x 16 x 16 inches ) . only one breeding pair per cage .
do not mix the different types of aurora finch as the birds will hybridize . the aurora is closely related to the melba finch and should not be housed with melba ' s so as to avoid hybridization .
diet / feeding : click on
feeding birds
web page for general details on the nutrition of non australian finches or read on for specific details for this finch .
the aurora finch requires a good quality finch seed mix , seeding grasses and some fruits ( e . g . apple ) and vegetables . leafy green vegetables can be offered , e . g . silverbeet , cos lettuce & endive . sprouted or soaked seed if available . live food is not essential during the non - breeding season but is beneficial . live food is essential during the breeding season . mealworms are commonly used . small crickets can be used .
nesting months : spring to early autumn , but may breed year round if conditions are suitable .
nesting receptacles : the aurora finch will build a dome shaped nest in a shrub or dry brush such as tea tree . equally it will build a nest in a wide variety of artificial nests .
nest : the cock bird will make a dome shaped nest from grasses , coconut fibre , moss and soft materials . nest is lined by the hen with feathers and soft fine grasses .
who incubates the eggs : hen at night / cock / both share during the day .
the nest is usually built at mid height in the aviary . nest inspections are not recommended . young should be removed from the parent birds as soon as they are fully independent so as to avoid possible aggression from a parent . more details on finch nests and a selection of finch nest photos can be located on the

do not mix the different types of aurora finch as the birds will hybridize . live food is essential during the breeding season . nest inspections are generally not tolerated . adequate new nest material must be available for the hen to rebuild the old nest or build a new nest for the next clutch . the aurora finch is closely related to the melba finch and should not be housed with melba ' s so as to avoid hybridization . it is best to restrict the adult breeding pair to 3 clutches per breeding season .
young birds ( when they become fully independent ) must be removed when bred in a cage . generally safe to remove the young from the parent birds about 4 weeks after they have left the nest .
