The Birds Portal

Birds are a group of warm-blooded vertebrates constituting the class Aves (/ˈeɪviːz/), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the 5.5 cm (2.2 in) bee hummingbird to the 2.8 m (9 ft 2 in) common ostrich. There are over 11,000 living species, more than half of which are passerine, or "perching" birds. Birds have wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. The study of birds is called ornithology.

Birds are feathered theropod dinosaurs and constitute the only known living dinosaurs. Likewise, birds are considered reptiles in the modern cladistic sense of the term, and their closest living relatives are the crocodilians. Birds are descendants of the primitive avialans (whose members include Archaeopteryx) which first appeared during the Late Jurassic. According to recent estimates, modern birds (Neornithes) evolved in the Late Cretaceous and diversified dramatically around the time of the Cretaceous–Paleogene extinction event 66 million years ago, which killed off the pterosaurs and all non-avian dinosaurs.

Many social species pass on knowledge across generations, which is considered a form of culture. Birds are social, communicating with visual signals, calls, and songs, and participating in such behaviours as cooperative breeding and hunting, flocking, and mobbing of predators. The vast majority of bird species are socially (but not necessarily sexually) monogamous, usually for one breeding season at a time, sometimes for years, and rarely for life. Other species have breeding systems that are polygynous (one male with many females) or, rarely, polyandrous (one female with many males). Birds produce offspring by laying eggs which are fertilised through sexual reproduction. They are usually laid in a nest and incubated by the parents. Most birds have an extended period of parental care after hatching.

Many species of birds are economically important as food for human consumption and raw material in manufacturing, with domesticated and undomesticated birds being important sources of eggs, meat, and feathers. Songbirds, parrots, and other species are popular as pets. Guano (bird excrement) is harvested for use as a fertiliser. Birds figure throughout human culture. About 120 to 130 species have become extinct due to human activity since the 17th century, and hundreds more before then. Human activity threatens about 1,200 bird species with extinction, though efforts are underway to protect them. Recreational birdwatching is an important part of the ecotourism industry.

  Subfossil skull and limb bones, 1879

  
  The Rodrigues parrot or Leguat's parrot (Necropsittacus rodricanus) is an extinct species of parrot that was endemic to the Mascarene island of Rodrigues. The species is known from subfossil bones and from mentions in contemporary accounts. It is unclear to which other species it is most closely related, but it is classified as a member of the tribe Psittaculini, along with other Mascarene parrots. The Rodrigues parrot bore similarities to the broad-billed parrot of Mauritius, and may have been related. Two additional species have been assigned to its genus (N. francicus and N. borbonicus), based on descriptions of parrots from the other Mascarene islands, but their identities and validity have been debated.
  
  The Rodrigues parrot was green, and had a proportionally large head and beak and a long tail. Its exact size is unknown, but it may have been around 50 cm (20 in) long. It was the largest parrot on Rodrigues, and it had the largest head of any Mascarene parrot. It may have looked similar to the great-billed parrot. By the time it was discovered, it frequented and nested on islets off southern Rodrigues, where introduced rats were absent, and fed on the seeds of the shrub Fernelia buxifolia. The species was last mentioned in 1761, and probably became extinct soon after, perhaps due to a combination of predation by introduced animals, deforestation, and hunting by humans.

  The elfin woods warbler (Setophaga angelae) is a species of bird endemic to Puerto Rico, where it is local and uncommon. Discovered in 1968 and described in 1972, it is the most recently described New World warbler (family Parulidae).
  
  The species name, angelae, is a tribute to Angela Kepler, one of its discoverers. These birds are insectivores, as they feed by gleaning small insects off the habitat leaves.
  
  Due to its small populations and restricted habitats, conservation efforts were begun in 1982 to protect this species, but as of 2005, the warbler was still in need of protection. The species is not in immediate danger as the majority of its habitat is protected forest, but introduced species (such as rats and small Asian mongooses), habitat reduction, and natural disasters represent potential threats to the population.

  Adult by Joseph Wolf, 1859

  
  The invisible rail, Wallace's rail, or drummer rail (Habroptila wallacii) is a large flightless rail that is endemic to the island of Halmahera in Northern Maluku, Indonesia, where it inhabits impenetrable sago swamps adjacent to forests. Its plumage is predominantly dark slate-grey, and the bare skin around its eyes, the long, thick bill, and the legs are all bright red. Its call is a low drumming sound which is accompanied by wing-beating. The difficulty of seeing this shy bird in its dense habitat means that information on its behaviour is limited.
  
  Recorded dietary items include sago shoots and insects, and it also swallows small stones to help break up its food. It is apparently monogamous, but little else is known of its courtship behaviour. The only known nest was a shallow bowl in the top of a rotting tree stump that was lined with wood chips and dry leaves. The two young chicks were entirely covered in black down typical of precocial newly hatched rails. The estimated population of 3,500–15,000 birds and the restricted range mean that the invisible rail is classified as vulnerable by the International Union for Conservation of Nature (IUCN). Habitat loss has occurred through the harvesting of sago and conversion of the wetlands to rice cultivation, and the rail is eaten by local people. The described nest was in an area frequented by local villagers, so the rail may be more adaptable to habitat changes than had been thought. (Full article...)

  Looking north across the reserve

  
  Cley Marshes is a 176-hectare (430-acre) nature reserve on the North Sea coast of England just outside the village of Cley next the Sea, Norfolk. A reserve since 1926, it is the oldest of the reserves belonging to the Norfolk Wildlife Trust (NWT), which is itself the oldest county Wildlife Trust in the United Kingdom. Cley Marshes protects an area of reed beds, freshwater marsh, pools and wet meadows and is part of the North Norfolk Coast Site of Special Scientific Interest (SSSI), Special Area of Conservation (SAC), Special Protection Area (SPA), and Ramsar Site due to the large numbers of birds it attracts.
  
  The reserve is important for some scarce breeding species, such as pied avocets on the islands, and western marsh harriers, Eurasian bitterns and bearded reedlings in the reeds, and is also a major migration stopoff and wintering site. There are also several nationally or locally scarce invertebrates and plants specialised for this coastal habitat. It has five bird hides and an environmentally friendly visitor centre and further expansion is planned through the acquisition of neighbouring land and improvements to visitor facilities.
  
  The site has a long history of human occupation, from prehistoric farming to its use as a prisoner of war camp in the Second World War. The reserve attracts large numbers of visitors, contributing significantly to the economy of Cley village. Despite centuries of embankment to reclaim land and protect the village, the marshes have been flooded many times, and the southward march of the coastal shingle bank and encroachment by the sea make it inevitable that the reserve will eventually be lost. New wetlands are being created further inland to compensate for the loss of coastal habitats. (Full article...)

  The white-eyed river martin (Pseudochelidon sirintarae) is a passerine bird, one of only two members of the river martin subfamily of the swallows. Since it has significant differences from its closest relative, the African river martin, it is sometimes placed in its own genus, Eurochelidon. First found in 1968, it is known only from a single wintering site in Thailand, and may be extinct, since it has not been seen since 1980 despite targeted surveys in Thailand and neighbouring Cambodia. It may possibly still breed in China or Southeast Asia, but a Chinese painting initially thought to depict this species was later reassessed as showing pratincoles.
  
  The adult white-eyed river martin is a medium-sized swallow, with mainly glossy greenish-black plumage, a white rump, and a tail which has two elongated slender central tail feathers, each widening to a racket-shape at the tip. It has a white eye ring and a broad, bright greenish-yellow bill. The sexes are similar in appearance, but the juvenile lacks the tail ornaments and is generally browner than the adult. Little is known of the behaviour or breeding habitat of this martin, although like other swallows it feeds on insects caught in flight, and its wide bill suggests that it may take relatively large species. It roosts in reed beds in winter, and may nest in river sandbanks, probably in April or May before the summer rains. It may have been overlooked prior to its discovery because it tended to feed at dawn or dusk rather than during the day.
  
  The martin's apparent demise may have been hastened by trapping, loss of habitat and the construction of dams. The winter swallow roosts at the only known location of this martin have greatly reduced in numbers, and birds breeding at river habitats have declined throughout the region. The white-eyed river martin is one of only two birds endemic to Thailand, and the country's government has noted this through the issues of a stamp and a high-value commemorative coin.

  The western yellow robin (Eopsaltria griseogularis) is a species of bird in the Australasian robin family, Petroicidae, native to Australia. Described by John Gould in 1838, the western yellow robin and its Australian relatives are not closely related to either the European or American robins, but they appear to be an early offshoot of the Passerida group of songbirds. Ranging between 13.5 and 15.5 cm (5+1⁄4 and 6 in) long, it has grey upperparts, and a grey breast and head, broken by whitish streaks near the bill and below the eye, with a conspicuous yellow belly. The sexes are similar in appearance. Two subspecies are recognized: subspecies griseogularis, which has a yellow rump, and subspecies rosinae with an olive-green rump.
  
  The species inhabits open eucalypt jungle, woodland, and scrub, generally favouring habitats with significant understory. Its range comprises the Southwest of Western Australia and the state's southern coastline, as well as the Eyre Peninsula in South Australia. It breeds in a cup-shaped nest in a tree. Predominantly insectivorous, the western yellow robin pounces on prey from a low branch or forages on the ground. Although it is rated as least concern on the International Union for Conservation of Nature (IUCN)'s Red List of Threatened Species, it has declined in parts of its range. (Full article...)

  Male T. m. merula

  
  The common blackbird (Turdus merula) is a species of true thrush. It is also called the Eurasian blackbird (especially in North America, to distinguish it from the unrelated New World blackbirds), or simply the blackbird where this does not lead to confusion with a similar-looking local species. It breeds in Europe, western Asia, and North Africa, and has been introduced to Australia and New Zealand. It has a number of subspecies across its large range; a few former Asian subspecies are now widely treated as separate species. Depending on latitude, the common blackbird may be resident, partially migratory, or fully migratory.
  
  The adult male of the common blackbird (Turdus merula merula, the nominate subspecies), which is found throughout most of Europe, is all black except for a yellow eye-ring and bill and has a rich, melodious song; the adult female and juvenile have mainly dark brown plumage. This species breeds in woods and gardens, building a neat, cup-shaped nest, bound together with mud. It is omnivorous, eating a wide range of insects, earthworms, berries, and fruits.
  
  Both sexes are territorial on the breeding grounds, with distinctive threat displays, but are more gregarious during migration and in wintering areas. Pairs stay in their territory throughout the year where the climate is sufficiently temperate. This common and conspicuous species has given rise to a number of literary and cultural references, frequently related to its song. (Full article...)

  The green rosella or Tasmanian rosella (Platycercus caledonicus) is a species of parrot native to Tasmania and Bass Strait islands. It was described by the German naturalist Johann Friedrich Gmelin in 1788, and named on the mistaken assumption it came from New Caledonia. At 14.5 in (37 cm) long it is the largest species of the rosella genus, Platycercus. Two subspecies are recognised. The green rosella's underparts, neck and head are yellow, with a red band above the beak and violet-blue cheeks. The back is mostly black and green, and its long tail blue and green. The sexes have similar plumage, except the female has duller yellow plumage and more prominent red markings, as well as a smaller beak. Juvenile and immature birds have predominantly green plumage.
  
  Found in a wide range of habitats with some form of tree cover, the green rosella is predominantly herbivorous, consuming seeds, berries, nuts and fruit, as well as flowers, but may also eat insect larvae and insects such as psyllids. Nesting takes place in tree hollows. Common and widespread across Tasmania, the green rosella is rated as least concern on the International Union for Conservation of Nature (IUCN)'s Red List of Endangered species. The King Island subspecies has been classed as vulnerable as its population has declined after much of its habitat on King Island was cleared. (Full article...)

  In Buenos Aires

  
  The white-rumped swallow (Tachycineta leucorrhoa) is a species of bird in the family Hirundinidae. First described and given its binomial name by French ornithologist Louis Pierre Vieillot in 1817, it was for many years considered a subspecies of the Chilean swallow. The species is monotypic with no known population variations. It has a white supraloral streak, or streak above its lores (the region between a bird's eye and nostrils), which can be used to differentiate it from the Chilean swallow. The lores, ear coverts, tail, and wings are black, with white tips on the inner secondaries, tertials, and greater coverts of the wings. The rest of the upperparts are a glossy blue. Its underparts and underwing-coverts are white, in addition to the rump, as the name suggests. The sexes are similar, and the juvenile is duller and browner with a dusky breast.
  
  This species usually builds its nest in holes in trees or dead snags or under or in artificial structures like fence posts and the eaves of buildings. The white-rumped swallow is solitary and nests in distributed pairs during the breeding season. The breeding season is from October to December in Brazil and from October to February in neighboring Argentina. Usually, only one brood with four to seven eggs is laid, although a second one will occasionally be laid. The female incubates the eggs over a period usually between 15 and 16 days, with the fledging usually occurring between 21 and 25 days after hatching.
  
  This swallow is found in Argentina, Bolivia, Brazil, Paraguay, Peru, and Uruguay. Its natural habitats are: (Full article...)

  Subfossil bones described in 1879, including two skulls, a pelvis, and limb bones

  
  The Rodrigues rail (Erythromachus leguati), also known as Leguat's gelinote or Leguat's rail, is an extinct species of the rail family that was endemic to the Mascarene island of Rodrigues. The bird was first documented from life by two accounts from 1691–93 and 1725–26. Subfossil remains were later discovered and correlated with the old accounts in 1874, and the species was named E. leguati in Leguat's honour. It is generally kept in its own genus, Erythromachus, but has sometimes been assigned to the genus Aphanapteryx along with its close relative the red rail (A. bonasia) of Mauritius; their relationship with other rails is unclear.
  
  The Rodrigues rail was about 35 cm (14 in) long and weighed at least 500 g (18 oz). It was described as having grey plumage, a red beak, red legs, and a naked red patch around the eye. The beak was long and curved downwards. It was flightless and fed on tortoise eggs. It was described as being attracted to red objects, which humans exploited while hunting it. The Rodrigues rail is believed to have become extinct in the mid-18th century mainly because of predation by introduced cats and hunting. (Full article...)

  Subspecies leachi

  
  The noisy miner (Manorina melanocephala) is a bird in the honeyeater family, Meliphagidae, and is endemic to eastern and southeastern Australia. This miner is a grey bird, with a black head, orange-yellow beak and feet, a distinctive yellow patch behind the eye, and white tips on the tail feathers. The Tasmanian subspecies has a more intense yellow panel in the wing, and a broader white tip to the tail. Males, females and juveniles are similar in appearance, though young birds are a brownish-grey. As the common name suggests, the noisy miner is a vocal species with a large range of songs, calls, scoldings and alarms, and almost constant vocalisations, particularly from young birds. One of four species in the genus Manorina, the noisy miner itself is divided into four subspecies. The separation of the Tasmanian M. m. leachi is of long standing, and the mainland birds were further split in 1999.
  
  Found in a broad arc from Far North Queensland through New South Wales and Victoria to Tasmania and southeastern South Australia, the noisy miner primarily inhabits dry, open eucalypt forests that lack understory shrubs. These include forests dominated by spotted gum, box and ironbark, as well as in degraded woodland where the understory has been cleared, such as recently burned areas, farming and grazing areas, roadside reserves, and suburban parks and gardens with trees and grass, but without dense shrubbery. The density of noisy miner populations has significantly increased in many locations across its range, particularly in human-dominated habitats. The popularity of nectar-producing garden plants, such as the large-flowered grevilleas, was thought to play a role in its proliferation, but studies now show that the noisy miner has benefited primarily from landscaping practices that create open areas dominated by eucalypts.
  
  Noisy miners are gregarious and territorial; they forage, bathe, roost, breed and defend territory communally, forming colonies that can contain several hundred birds. Each bird has an 'activity space', and birds with overlapping activity spaces form associations called 'coteries', which are the most stable units within the colony. The birds also form temporary flocks called 'coalitions' for specific activities, such as mobbing a predator. Group cohesion is facilitated not only by vocalisations, but also through ritualised displays, which have been categorised as flight displays, postural displays, and facial displays. The noisy miner is a notably aggressive bird, so that chasing, pecking, fighting, scolding, and mobbing occur throughout the day, targeted at both intruders and colony members. (Full article...)

  Breeding-plumaged adult in Wakodahatchee Wetlands

  
  The cattle egret (Bubulcus) is a cosmopolitan genus of heron (family Ardeidae) found in the tropics, subtropics, and warm-temperate zones. According to the IOC bird list, it contains two species, the western cattle egret and the eastern cattle egret, although some authorities regard them as a single species. Despite the similarities in plumage to the egrets of the genus Egretta, it is more closely related to the herons of Ardea. Originally native to parts of Asia, Africa, and Europe, it has undergone a rapid expansion in its distribution and successfully colonised much of the rest of the world in the last century.
  
  They are white birds adorned with buff plumes in the breeding season. They nest in colonies, usually near bodies of water and often with other wading birds. The nest is a platform of sticks in trees or shrubs. Cattle egrets exploit drier and open habitats more than other heron species. Their feeding habitats include seasonally inundated grasslands, pastures, farmlands, wetlands, and rice paddies. They often accompany cattle or other large mammals, catching insect and small vertebrate prey disturbed by these animals. Some populations are migratory and others show postbreeding dispersal.
  
  The adult cattle egret has few predators, but birds or mammals may raid its nests, and chicks may be lost to starvation, calcium deficiency, or disturbance from other large birds. This genus maintains a special relationship with cattle, which extends to other large grazing mammals; wider human farming is believed to be a major cause of their suddenly expanded range. The cattle egret removes ticks and flies from cattle and consumes them. This benefits both organisms, but it has been implicated in the spread of tick-borne animal diseases. (Full article...)

  The letter-winged kite (Elanus scriptus) is a small, rare and irruptive bird of prey that is found only in Australia. Measuring around 35 cm (14 in) in length with a wingspan of 84–100 cm (33–39 in), the adult letter-winged kite has predominantly pale grey and white plumage and prominent black rings around its red eyes. Its name derives from its highly distinctive black underwing pattern of a shallow 'M' or 'W' shape, visible when in flight. This distinguishes it from the otherwise similar black-shouldered kite. This species is also the only nocturnal species within the order Accipitriformes despite few differences found in its visual anatomy to other closely related kites.
  
  The species begins breeding in response to rodent outbreaks, with pairs nesting in loose colonies of up to 50 birds each. Three to four eggs are laid and incubated for around thirty days, though the eggs may be abandoned if the food source disappears. Chicks are fledged within five weeks of hatching. Roosting in well-foliaged trees during the day, the letter-winged kite hunts mostly at night. It is a specialist predator of rodents, which it hunts by hovering above grasslands and fields. It is rated as near threatened on the International Union for Conservation of Nature (IUCN)'s Red List of Threatened Species. (Full article...)

  Male at Head Marala, Punjab, Pakistan
  

  
  The Sind sparrow (Passer pyrrhonotus) is a passerine bird of the sparrow family, Passeridae, found around the Indus valley region in South Asia. Its name refers to the province of Sindh, and it is also known as the jungle, Sind jungle, or rufous-backed sparrow. Very similar to the related house sparrow, it is smaller and has distinguishing plumage features. As in the house sparrow, the male has brighter plumage than female and young birds, including black markings and a grey crown. Distinctively, the male has a chestnut stripe running down its head behind the eye, and the female has a darker head than other sparrow species. Its main vocalisations are soft chirping calls that are extended into longer songs with other sounds interspersed by breeding males. Historically, this species was thought to be very closely related to the house sparrow, but its closest evolutionary affinities may lie elsewhere. The species was discovered around 1840, but went undetected for several decades afterwards.
  
  Within its Indus valley breeding range in Pakistan and western India, the Sind sparrow is patchily distributed in riverine and wetland habitats with thorny scrub and tall grass. During the non-breeding season, some birds enter drier habitats as they disperse short distances from their breeding habitat, or migrate into western Pakistan and the extreme east of Iran. Since this species is fairly common and expanding its range, it is assessed as least concern on the IUCN Red List. The Sind sparrow is social while feeding and gathers in small groups both while breeding and during winter dispersal. It feeds mostly on seeds and less often on insects, foraging close to the ground. Nests are made in the branches of thorny trees, and are untidy globular masses constructed from grass or other plant matter and lined with softer material. Both sexes are involved in building the nest and caring for the young, and usually raise two clutches of three to five young each breeding season. (Full article...)

  C. a. brasiliensis
  Peten, Guatemala

  
  The black vulture (Coragyps atratus), also known as the American black vulture, Mexican vulture, zopilote, urubu, or gallinazo, is a bird in the New World vulture family whose range extends from the southeastern United States to Perú, Central Chile and Uruguay in South America. Although a common and widespread species, it has a somewhat more restricted distribution than its compatriot, the turkey vulture, which breeds well into Canada and all the way south to Tierra del Fuego. It is the only extant member of the genus Coragyps, which is in the family Cathartidae. Despite the similar name and appearance, this species is not closely related to the Eurasian black vulture, an Old World vulture, of the family Accipitridae (which includes raptors like the eagles, hawks, kites, and harriers). For ease of locating animal corpses (their main source of sustenance), black vultures tend to inhabit relatively open areas with scattered trees, such as chaparral, in addition to subtropical forested areas and parts of the Brazilian pantanal.
  
  With a wingspan of 1.5 m (4.9 ft), the black vulture is an imposing bird, though relatively small for a vulture, let alone a raptor. It has black plumage, a featherless, grayish-black head and neck, and a short, hooked beak. These features are all evolutionary adaptations to life as a scavenger; their black plumage stays visibly cleaner than that of a lighter-colored bird, the bare head is designed for easily digging inside animal carcasses, and the hooked beak is built for stripping the bodies clean of meat. The absence of head-feathers helps the birds stay clean and remain (more or less) free of animal blood and bodily fluids, which could become problematic for the vultures and attract parasites; most vultures are known to bathe after eating, provided there is a water source. This water source can be natural or man-made, such as a stream or a livestock water tank.
  
  The black vulture is a scavenger and feeds on carrion, but will also eat eggs, small reptiles, or small newborn animals (livestock such as cattle, or deer, rodents, rabbits, etc.), albeit very rarely. They will also opportunistically prey on extremely weakened, sick, elderly, or otherwise vulnerable animals. In areas populated by humans, it also scavenges at dumpster sites and garbage dumps. It finds its meals either by using its keen eyesight or by following other (New World) vultures, which all possess a keen sense of smell. Lacking a syrinx—the vocal organ of birds—its only vocalizations are grunts or low hisses. It lays its eggs in caves, in cliffside rock crevasses, dead and hollow trees or, in the absence of predators, on the bare ground, generally raising two chicks each year. The parents feed their young by regurgitation from their crop, an additional digestive organ unique to birds, used for storing excess food; their “infant formula”, of sorts, is thus called “crop milk”. In the United States, the vulture receives legal protection under the Migratory Bird Treaty Act of 1918 despite the fact it does not migrate whatsoever. This vulture also appeared in Mayan codices.

  In Cooper Bay, South Georgia

  
  The macaroni penguin (Eudyptes chrysolophus) is a species of penguin found from the Subantarctic to the Antarctic Peninsula. One of six species of crested penguin, it is very closely related to the royal penguin, and some authorities consider the two to be a single species. It bears a distinctive yellow crest that resembles macaroni, from which its name is derived. Its face and upperparts are black and sharply delineated from the white underparts. Adults weigh on average 5.5 kg (12 lb) and are 70 cm (28 in) in length. The male and female are similar in appearance; the male is slightly larger and stronger with a relatively larger bill. Like all penguins, it is flightless, with a streamlined body and wings stiffened and flattened into flippers for a marine lifestyle.
  
  Its diet consists of a variety of crustaceans, mainly krill, as well as small fish and cephalopods; the species consumes more marine life annually than any other species of seabird. These birds moult once a year, spending about three to four weeks ashore, before returning to the sea. Numbering up to 100,000 individuals, the breeding colonies of the macaroni penguin are among the largest and densest of all penguin species. After spending the summer breeding, penguins disperse into the oceans for six months; a 2009 study found that macaroni penguins from Kerguelen travelled over 10,000 km (6,200 mi) in the central Indian Ocean. With about 18 million individuals, the macaroni penguin is the most numerous penguin species. Widespread declines in populations have been recorded since the mid-1970s and their conservation status is classified as vulnerable. (Full article...)

  Near Kurnell, New South Wales

  
  The Australian raven (Corvus coronoides) is a passerine corvid bird native to Australia. Measuring 46–53 centimetres (18–21 in) in length, it has an all-black plumage, beak and mouth, as well as strong, greyish-black legs and feet. The upperparts of its body are glossy, with a purple-blue, greenish sheen; its black feathers have grey bases. The Australian raven is distinguished from the Australian crow, and other related corvids, by its long chest feathers, or throat hackles, which are prominent in mature birds. Older individuals and subadults have white irises, while the younger birds' eyes display blue inner rims; hatchlings and young birds have brown, dark irises until about fifteen months of age, at which point their irises become hazel-coloured, with an inner blue rim around each pupil, this lasting until they are roughly 2.5 to 3 years of age. Nicholas Aylward Vigors and Thomas Horsfield described the Australian raven in 1827, its species name coronoides highlighting its similarity with the carrion crow (C. corone). Two subspecies are recognised, which differ slightly in their vocalisations, and are quite divergent, genetically.
  
  The preferred habitat of the Australian raven includes open woodlands and transitional zones, in addition to cities and towns; it has adapted well to human settlements and other urban environments, and is a commonly sighted bird in several major cities, including Sydney, Canberra, Perth, Adelaide and Brisbane. The Australian raven is territorial, with pairs generally bonding for life. Breeding takes place between July and September, with almost no variation across its range. The nest is a bowl-shaped structure of sticks sited high in a tree, or occasionally in a man-made structure such as a windmill or other building.
  
  An omnivorous and opportunistic feeder, the Australian raven eats a wide variety of plant and animal material, from fruits and seeds to lizards, chicks of other bird species, and small mammals; they will also scour waste bins and disposal sites for human food waste, such as various produce, meats, seafood, eggs, etc. The ravens living in eastern Australia are often associated with sheep farms, and have been blamed for the killing of lambs; however, this is an exceedingly rare occurrence, as the ravens are likely seeking the afterbirth from ewes that may have recently given birth. Additionally, ravens aid in environmental "cleanup"—much like vultures on other continents—by helping rid the area of potentially dangerous pathogens which could deploy on carrion, stillborn farm animals (or other deceased mammals and birds), even scavenging newborn mammalian faeces.

  The rainbow pitta (Pitta iris) is a small passerine bird in the pitta family, Pittidae, endemic to northern Australia, most closely related to the superb pitta of Manus Island. It has a velvet black head with chestnut stripes above the eyes, olive green upper parts, black underparts, a bright red belly and an olive green tail. An Australian endemic, it lives in the monsoon forests and in some drier eucalypt forests.
  
  Like other pittas, the rainbow pitta is a secretive and shy bird. Its diet is mainly insects, arthropods and small vertebrates. Pairs defend territories and breed during the rainy season, as that time of year provides the most food for nestlings. The female lays three to five blotched eggs inside its large domed nest. Both parents defend the nest, incubate the eggs and feed the chicks. Although the species has a small global range, it is locally common and the International Union for Conservation of Nature (IUCN) has assessed it as being of least concern. (Full article...)

  Killdeer in breeding plumage.

  
  The killdeer (Charadrius vociferus) is a large plover found in the Americas. It gets its name from its shrill, two-syllable call, which is often heard. It was described and given its current scientific name in 1758 by Carl Linnaeus in the 10th edition of his Systema Naturae. Three subspecies are described. Its upperparts are mostly brown with rufous fringes, the head has patches of white and black, and two black bands cross the breast. The belly and the rest of the breast are white. The nominate (or originally described) subspecies breeds from southeastern Alaska and southern Canada to Mexico. It is seen year-round in the southern half of its breeding range; the subspecies C. v. ternominatus is resident in the West Indies, and C. v. peruvianus inhabits Peru and surrounding South American countries throughout the year. North American breeders winter from their resident range south to Central America, the West Indies, and the northernmost portions of South America.
  
  The nonbreeding habitat of the killdeer includes coastal wetlands, beach habitats, and coastal fields. Its breeding grounds are generally open fields with short vegetation (but locations such as rooftops are sometimes used); although it is a shorebird, it does not necessarily nest close to water. The nest itself is a scrape lined with vegetation and white material, such as pebbles or seashell fragments. This bird lays a clutch of four to six buff to beige eggs with dark markings. The breeding season (starting with egg-laying) occurs from mid-March to August, with later timing of egg-laying in the northern portion of the range. Both parents incubate the eggs for 22 to 28 days typically. The young stay in the nest until the day after being hatched, when they are led by their parents to a feeding territory (generally with dense vegetation where hiding spots are abundant), where the chicks feed themselves. The young then fledge about 31 days after hatching, and breeding first occurs after one year of age.
  
  The killdeer primarily feeds on insects, although other invertebrates and seeds are eaten. It forages almost exclusively in fields, especially those with short vegetation and with cattle and standing water. It primarily forages during the day, but in the nonbreeding season, when the moon is full or close to full, it forages at night, likely because of increased insect abundance and reduced predation during the night. Predators of the killdeer include various birds and mammals. Its multiple responses to predation range from calling to the "ungulate display", which can be fatal for the performing individual. This bird is classified as least concern by the International Union for Conservation of Nature, because of its large range and population. Its population is declining, but this trend is not severe enough for the killdeer to be considered a vulnerable species. It is protected by the American Migratory Bird Treaty Act of 1918 and the Canadian Migratory Birds Convention Act. (Full article...)

Selected general bird topic

The extinction of the dusky seaside sparrow was caused by habitat loss.

Bird conservation is a field in the science of conservation biology related to threatened birds. Humans have had a profound effect on many bird species. Over one hundred species have gone extinct in historical times, although the most dramatic human-caused extinctions occurred in the Pacific Ocean as humans colonised the islands of Melanesia, Polynesia and Micronesia, during which an estimated 750–1,800 species of birds became extinct. According to Worldwatch Institute, many bird populations are currently declining worldwide, with 1,200 species facing extinction in the next century. The biggest cited reason surrounds habitat loss. Other threats include overhunting, accidental mortality due to structural collisions, long-line fishing bycatch, pollution, competition and predation by pet cats, oil spills and pesticide use and climate change. Governments, along with numerous conservation charities, work to protect birds in various ways, including legislation, preserving and restoring bird habitat, and establishing captive populations for reintroductions.

See Late Quaternary prehistoric birds for birds which disappeared in prehistoric and early historic times, usually due to human activity (i.e., starting with the Upper Paleolithic Revolution). For birds having gone extinct in modern times (since 1500), see List of extinct birds. (Full article...)

Selected taxon

Sulphur-crested Cockatoo

A cockatoo is any of the 21 species of parrots belonging to the family Cacatuidae, the only family in the superfamily Cacatuoidea. Along with the Psittacoidea (true parrots) and the Strigopoidea (large New Zealand parrots), they make up the order Psittaciformes. The family has a mainly Australasian distribution, ranging from the Philippines and the eastern Indonesian islands of Wallacea to New Guinea, the Solomon Islands and Australia.

Cockatoos are recognisable by the prominent crests and curved bills. Their plumage is generally less colourful than that of other parrots, being mainly white, grey or black and often with coloured features in the crest, cheeks or tail. On average they are larger than other parrots; however, the cockatiel, the smallest cockatoo species, is a small bird. The phylogenetic position of the cockatiel remains unresolved, except that it is one of the earliest offshoots of the cockatoo lineage. The remaining species are in two main clades. The five large black-coloured cockatoos of the genus Calyptorhynchus form one branch. The second and larger branch is formed by the genus Cacatua, comprising 11 species of white-plumaged cockatoos and four monotypic genera that branched off earlier; namely the pink and white pink cockatoo, the pink and grey galah, the mainly grey gang-gang cockatoo and the large black-plumaged palm cockatoo.

Cockatoos prefer to eat seeds, tubers, corms, fruit, flowers and insects. They often feed in large flocks, particularly when ground-feeding. Cockatoos are monogamous and nest in tree hollows. Some cockatoo species have been adversely affected by habitat loss, particularly from a shortage of suitable nesting hollows after large mature trees are cleared; conversely, some species have adapted well to human changes and are considered agricultural pests.

Selected bird anatomy topic

The barn owl, Tyto alba, has a prominent heart-shaped facial disc that aids it during hunting.

In ornithology, the facial disc is the concave collection of feathers on the face of some birds—most notably owls—surrounding the eyes. The concavity of the facial disc forms a circular paraboloid that collects sound waves and directs those waves towards the owl's ears. The feathers making up this disc can be adjusted by the bird to alter the focal length of this sound collector, enabling the bird to focus at different distances and allowing it to locate prey by sound alone under snow, grass, and plant cover.

Other bird species, such as harriers, have less prominent facial discs. In harriers, the related term facial ruff refers to feathers around the neck that are raised in response to noise, essentially enlarging the facial disc and improving hearing. (Full article...)

Selected species

The splendid fairy-wren (Malurus splendens), also known simply as the splendid wren or more colloquially in Western Australia as the blue wren, is a passerine bird of the family Maluridae. It is found across much of the Australian continent from central-western New South Wales and southwestern Queensland over to coastal Western Australia. The male in breeding plumage is a small, long-tailed bird of predominantly bright blue and black colouration. Non-breeding males, females and juveniles are predominantly grey-brown in colour. It comprises several similar all-blue and black subspecies that were originally considered separate species. Like other fairy-wrens, the splendid fairy-wren is notable for several peculiar behavioural characteristics; birds are socially monogamous and sexually promiscuous. Male wrens pluck pink or purple petals and display them to females as part of a courtship display. The habitat of the splendid fairy-wren ranges from forest to dry scrub, generally with ample vegetation for shelter. It has not adapted well to human occupation of the landscape and has disappeared from some urbanized areas. The splendid fairy-wren mainly eats insects and supplements its diet with seeds.
