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.

  Salt marsh near Brancaster Staithe

  
  The North Norfolk Coast Site of Special Scientific Interest (SSSI) is an area of European importance for wildlife in Norfolk, England. It comprises 7,700 ha (19,027 acres) of the county's north coast from just west of Holme-next-the-Sea to Kelling, and is additionally protected through Natura 2000, Special Protection Area (SPA) listings; it is also part of the Norfolk Coast Area of Outstanding Natural Beauty (AONB). The North Norfolk Coast is also designated as a wetland of international importance on the Ramsar list and most of it is a Biosphere Reserve.
  
  Habitats within the SSSI include reed beds, salt marshes, freshwater lagoons and sand or shingle beaches. The wetlands are important for wildlife, including some scarce breeding birds such as pied avocets, western marsh harriers, Eurasian bitterns and bearded reedlings. The location also attracts migrating birds including vagrant rarities. Ducks and geese winter along this coast in considerable numbers, and several nature reserves provide suitable conditions for water voles, natterjack toads and several scarce plants and invertebrates.
  
  The area is archaeologically significant, with artefacts dating back to the Upper Paleolithic. The mound of an Iron Age fort is visible at Holkham, and the site of a 23 ha (57 acres) Roman naval port with a fort built on the castrum pattern is just outside Brancaster. The site of the medieval "chapel" (probably a domestic dwelling) at Blakeney is no longer accessible. Remains of military use from both world wars include an armoured fighting vehicle gunnery range, a hospital and bombing ranges, as well as passive defences such as pillboxes, barbed wire and tank traps.

  Adult in breeding plumage

  
  The pigeon guillemot (Cepphus columba) (/ˈɡɪlɪmɒt/) is a species of bird in the auk family, Alcidae. One of three species in the genus Cepphus, it is most closely related to the spectacled guillemot. There are five subspecies of the pigeon guillemot; all subspecies, when in breeding plumage, are dark brown with a black iridescent sheen and a distinctive wing patch broken by a brown-black wedge. Its non-breeding plumage has mottled grey and black upperparts and white underparts. The long bill is black, as are the claws. The legs, feet, and inside of the mouth are red. It closely resembles the black guillemot, which is slightly smaller and lacks the dark wing wedge present in the pigeon guillemot.
  
  This seabird is found on North Pacific coastal waters, from Siberia through Alaska to California. The pigeon guillemot breeds and sometimes roosts on rocky shores, cliffs, and islands close to shallow water. In the winter, some birds move slightly south in the northernmost part of their range in response to advancing ice and migrate slightly north in the southern part of their range, generally preferring more sheltered areas.
  
  This species feeds on small fish and marine invertebrates, mostly near the sea floor, that it catches by pursuit diving. Pigeon guillemots are monogamous breeders, nesting in small colonies close to the shore. They defend small territories around a nesting cavity, in which they lay one or two eggs. Both parents incubate the eggs and feed the chicks. After leaving the nest the young bird is completely independent of its parents. Several birds and other animals prey on the eggs and chicks.

  A grey seal (Halichoerus grypus) feeding a pup, island of Skye.

  
  The fauna of Scotland is generally typical of the northwest European part of the Palearctic realm, although several of the country's larger mammals were hunted to extinction in historic times and human activity has also led to various species of wildlife being introduced. Scotland's diverse temperate environments support 62 species of wild mammals, including a population of wild cats, important numbers of grey and harbour seals and the most northerly colony of bottlenose dolphins in the world.
  
  Many populations of moorland birds, including the black and red grouse live here, and the country has internationally significant nesting grounds for seabirds such as the northern gannet. The golden eagle has become a national icon, and white-tailed eagles and ospreys have recently re-colonised the land. The Scottish crossbill is the only endemic vertebrate species in the UK.
  
  Scotland's seas are among the most biologically productive in the world; it is estimated that the total number of Scottish marine species exceeds 40,000. The Darwin Mounds are an important area of deep sea cold water coral reefs discovered in 1998. Inland, nearly 400 genetically distinct populations of Atlantic salmon live in Scottish rivers. Of the 42 species of fish found in the country's fresh waters, half have arrived by natural colonisation and half by human introduction. (Full article...)

  Illustration from 1861 Ibis article.

  
  The African river martin (Pseudochelidon eurystomina) is a passerine bird, one of two members of the river martin subfamily of the swallow family, Hirundinidae. When discovered, it was not initially recognised as a swallow, and its structural differences from most of its relatives, including its stout bill and robust legs and feet, have led to its current placement in a separate subfamily shared only with the Asian white-eyed river martin. The African river martin is a large swallow, mainly black with a blue-green gloss to the head and a greener tint to the back and wings. The under-wings are brownish, the underparts are purple-black, and the flight feathers are black. This martin has red eyes, a broad orange-red bill and a black, square tail. Young birds are similar in appearance to the adults, but have browner plumage. This species has a variety of unmusical calls, and displays both in flight and on the ground, although the purpose of the terrestrial display is unknown.
  
  The main breeding areas are in the Democratic Republic of the Congo (DRC) along the Congo River and its tributary, the Ubangi, in habitats characterised by a mixture of tropical forest types including swampy or seasonally flooded woodland. The African river martin is migratory, wintering in coastal savanna in southern Gabon and the Republic of the Congo. Breeding also occurs in these coastal areas, but it is unknown whether the migrants are raising a second brood or if there is a separate resident population. This martin feeds in flocks throughout the year, catching a variety of insects in the air, especially flying ants. It does not use perches during the breeding season, although it will often land on the ground.
  
  The African river martin nests in burrows in river sand banks, often alongside rosy bee-eaters, but its incubation and fledging times are not known. It also digs tunnels for night-time shelter when in its wintering areas. It appears to be common within its restricted range, despite being caught in large numbers by the local population for food, and large flocks are sometimes seen. However, due to a lack of detailed information about its breeding range and population numbers, this species is classed as Data Deficient by the International Union for Conservation of Nature (IUCN).

  Coloeus monedula
  

  Western jackdaw calls (Estonia)

  
  The western jackdaw (Coloeus monedula), also known as the Eurasian jackdaw, the European jackdaw, or simply the jackdaw, is a passerine bird in the crow family. Found across Europe, western Asia and North Africa; it is mostly resident, although northern and eastern populations migrate south in the winter. Four subspecies are recognised, which differ mainly in the colouration of the plumage on the head and nape. Linnaeus first described it formally, giving it the name Corvus monedula. The common name derives from the word jack, denoting "small", and daw, a less common synonym for "jackdaw", and the native English name for the bird.
  
  Measuring 34–39 centimetres (13–15 in) in length, the western jackdaw is a black-plumaged bird with a grey nape and distinctive pale-grey irises. It is gregarious and vocal, living in small groups with a complex social structure in farmland, open woodland, on coastal cliffs, and in urban settings. Like its relatives, jackdaws are intelligent birds, and have been observed using tools. An omnivorous and opportunistic feeder, it eats a wide variety of plant material and invertebrates, as well as food waste from urban areas. Western jackdaws are monogamous and build simple nests of sticks in cavities in trees, cliffs, or buildings. About five pale blue or blue-green eggs with brown speckles are laid and incubated by the female. The young fledge in four to five weeks. (Full article...)

  Adult of nominate subspecies in Switzerland

  
  The Alpine chough (/ˈtʃʌf/) or yellow-billed chough (Pyrrhocorax graculus) is a bird in the crow family, one of only two species in the genus Pyrrhocorax. Its two subspecies breed in high mountains from Spain eastwards through southern Europe and North Africa to Central Asia and Nepal, and it may nest at a higher altitude than any other bird. The eggs have adaptations to the thin atmosphere that improve oxygen take-up and reduce water loss.
  
  This bird has glossy black plumage, a yellow beak, red legs, and distinctive calls. It has a buoyant acrobatic flight with widely spread flight feathers. The Alpine chough pairs for life and displays fidelity to its breeding site, which is usually a cave or crevice in a cliff face. It builds a lined stick nest and lays three to five brown-blotched whitish eggs. It feeds, usually in flocks, on short grazed grassland, taking mainly invertebrate prey in summer and fruit in winter; it will readily approach tourist sites to find supplementary food.
  
  Although it is subject to predation and parasitism, and changes in agricultural practices have caused local population declines, this widespread and abundant species is not threatened globally. Climate change may present a long-term threat, by shifting the necessary Alpine habitat to higher altitudes. (Full article...)

  Male breeding plumage of Q. q. lathamii

  
  The red-billed quelea (/ˈkwiːliə/; Quelea quelea), also known as the red-billed weaver or red-billed dioch, is a small—approximately 12 cm (4.7 in) long and weighing 15–26 g (0.53–0.92 oz)—migratory, sparrow-like bird of the weaver family, Ploceidae, native to Sub-Saharan Africa.
  
  It was named by Linnaeus in 1758, who considered it a bunting, but Ludwig Reichenbach assigned it in 1850 to the new genus Quelea. Three subspecies are recognised, with Quelea quelea quelea occurring roughly from Senegal to Chad, Q. q. aethiopica from Sudan to Somalia and Tanzania, and Q. q. lathamii from Gabon to Mozambique and South Africa. Non-breeding birds have light underparts, striped brown upper parts, yellow-edged flight feathers and a reddish bill. Breeding females attain a yellowish bill. Breeding males have a black (or rarely white) facial mask, surrounded by a purplish, pinkish, rusty or yellowish wash on the head and breast. The species avoids forests, deserts and colder areas such as those at high altitude and in southern South Africa. It constructs oval roofed nests woven from strips of grass hanging from thorny branches, sugar cane or reeds. It breeds in very large colonies.
  
  The quelea feeds primarily on seeds of annual grasses, but also causes extensive damage to cereal crops. Therefore, it is sometimes called "Africa's feathered locust". The usual pest-control measures are spraying avicides or detonating fire-bombs in the enormous colonies during the night. Extensive control measures have been largely unsuccessful in limiting the quelea population. When food runs out, the species migrates to locations of recent rainfall and plentiful grass seed; hence it exploits its food source very efficiently. It is regarded as the most numerous undomesticated bird on earth, with the total post-breeding population sometimes peaking at an estimated 1.5 billion individuals. It feeds in huge flocks of millions of individuals, with birds that run out of food at the rear flying over the entire group to a fresh feeding zone at the front, creating an image of a rolling cloud. The conservation status of red-billed quelea is least concern according to the IUCN Red List. (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...)

  The northern rosella (Platycercus venustus), formerly known as Brown's rosella or the smutty rosella, is a species of parrot native to northern Australia, ranging from the Gulf of Carpentaria and Arnhem Land to the Kimberley. It was described by Heinrich Kuhl in 1820, and two subspecies are recognised. The species is unusually coloured for a rosella, with a dark head and neck with pale cheeks—predominantly white in the subspecies from the Northern Territory and blue in the Western Australian subspecies hillii. The northern rosella's mantle and scapulars are black with fine yellow scallops, while its back, rump and underparts are pale yellow with fine black scallops. The long tail is blue-green, and the wings are black and blue-violet. The sexes have similar plumage, while females and younger birds are generally duller with occasional spots of red.
  
  Found in woodland and open savanna country, the northern rosella is predominantly herbivorous, consuming seeds, particularly of grasses and eucalypts, as well as flowers and berries, but it may also eat insects. Nesting takes place in tree hollows. Although uncommon, the northern rosella is rated as least concern on the International Union for Conservation of Nature (IUCN)'s Red List of Threatened Species.

  Males in breeding plumage in the Netherlands

  
  The ruff (Calidris pugnax) is a medium-sized wading bird that breeds in marshes and wet meadows across northern Eurasia. This highly gregarious sandpiper is migratory and sometimes forms huge flocks in its winter grounds, which include southern and western Europe, Africa, southern Asia and Australia.
  
  The ruff is a long-necked, pot-bellied bird. This species shows marked sexual dimorphism; the male is much larger than the female (the reeve), and has a breeding plumage that includes brightly coloured head tufts, bare orange facial skin, extensive black on the breast, and the large collar of ornamental feathers that inspired this bird's English name. The female and the non-breeding male have grey-brown upperparts and mainly white underparts. Three differently plumaged types of male, including a rare form that mimics the female, use a variety of strategies to obtain mating opportunities at a lek, and the colourful head and neck feathers are erected as part of the elaborate main courting display. The female has one brood per year and lays four eggs in a well-hidden ground nest, incubating the eggs and rearing the chicks, which are mobile soon after hatching, on her own. Predators of wader chicks and eggs include mammals such as foxes, feral cats and stoats, and birds such as large gulls, corvids and skuas.
  
  The ruff forages in wet grassland and soft mud, probing or searching by sight for edible items. It primarily feeds on insects, especially in the breeding season, but it will consume plant material, including rice and maize, on migration and in winter. Classified as "least concern" on the IUCN Red List criteria, the global conservation concerns are relatively low because of the large numbers that breed in Scandinavia and the Arctic. However, the range in much of Europe is contracting because of land drainage, increased fertiliser use, the loss of mown or grazed breeding sites, and over-hunting. This decline has seen it listed in the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA). (Full article...)

  View of upperparts

  
  Zino's petrel (Pterodroma madeira) or the freira, is a species of small seabird in the gadfly petrel genus, endemic to the island of Madeira. This long-winged petrel has a grey back and wings, with a dark "W" marking across the wings, and a grey upper tail. The undersides of the wings are blackish apart from a triangle of white at the front edge near the body, and the belly is white with grey flanks. It is very similar in appearance to the slightly larger Fea's petrel, and separating these two Macaronesian species at sea is very challenging. It was formerly considered to be a subspecies of the soft-plumaged petrel, P. mollis, but they are not closely related, and Zino's was raised to the status of a species because of differences in morphology, calls, breeding behaviour and mitochondrial DNA. It is one of Europe's most endangered seabirds, with breeding areas restricted to a few ledges high in the central mountains of Madeira.
  
  Zino's petrel nests in burrows which are visited only at night, when they give their haunting calls. The single white egg is incubated by both adults, one sitting during the day while the other feeds on fish and squid at sea. Eggs, chicks and adults have been subject to predation by introduced cats and rats, and in the past have been taken for food by local shepherds. Predator control, and other measures such as the removal of grazing animals that trample the burrows, have enabled the population to recover to 65–80 breeding pairs; the species remains listed as endangered on the IUCN Red List. However, conservation efforts had a major setback in August 2010 when fires killed three adults and 65 percent of the chicks. The population eventually recovered and was stable at 160 individuals by 2018. (Full article...)

  The Perijá tapaculo (Scytalopus perijanus) is a species of passerine bird in the family Rhinocryptidae (tapaculos). Endemic to the Serranía del Perijá mountain range on the Colombia–Venezuela border, the Perijá tapaculo is found at altitudes of 1,600–3,225 metres (5,200–10,600 feet). Its body is 10 to 12 centimetres (3.9 to 4.7 inches) long and its tail is about 4 cm (1.6 in) long. Specimens have long been stored in museums, but the species was described only in 2015 based on sixteen specimens found between July 2008 and February 2009. It is considered vulnerable to extinction.
  
  Adults have neutral grey heads, brown necks, brown-sepia striped backs, and grey-white bellies, breasts, and throats. Males have some buff markings on their breasts, and less sharp brown spots on their napes than females. The Perijá tapaculo is a secretive bird and therefore difficult to observe; as a result its ecology is poorly known. It feeds on insects and reproduces between April and July. Its range is partially within Chamicero de Perijá Bird Reserve in Colombia and the Sierra de Perijá National Park in Venezuela. (Full article...)

  Nyamebe Bepo Forest Reserve
  Ashanti Region, Ghana

  
  The white-necked rockfowl (Picathartes gymnocephalus) is a medium-sized bird in the family Picathartidae, with a long neck and tail. Also known as the white-necked picathartes, this passerine is mainly found in rocky forested areas at higher altitudes in West Africa from Guinea to Ghana. Its distribution is patchy, with populations often being isolated from each other. The rockfowl typically chooses to live near streams and inselbergs. It has no recognized subspecies, though some believe that it forms a superspecies with the grey-necked rockfowl. The white-necked rockfowl has greyish-black upperparts and white underparts. Its unusually long, dark brown tail is used for balance, and its thighs are muscular. The head is nearly featherless, with the exposed skin being bright yellow except for two large, circular black patches located just behind the eyes. Though the bird is usually silent, some calls are known.
  
  These rockfowl feed primarily on insects, though parents feed small frogs to their young. One feeding strategy involves following Dorylus army ant swarms, feeding on insects flushed by the ants. Rockfowl move through the forest primarily through a series of hops and bounds or short flights in low vegetation. This species rarely flies for long distances. The white-necked rockfowl is monogamous and pairs nest either alone or in the vicinity of other pairs, sometimes in colonies with as many as eight nests. These nests are constructed out of mud formed into a deep cup and are built on rock surfaces, typically in caves. Two eggs are laid twice a year. Though the birds breed in colonies, infanticide is fairly common in this species, with rockfowl attempting to kill the young of other pairs. Nestlings mature in about a month. This bird is long-lived.
  
  This species is classified as Vulnerable as its dwindling and fragmented populations are threatened by habitat destruction. Conservation efforts are underway in parts of its range in the form of habitat protection, education efforts, and new laws. Some of the indigenous peoples of Sierra Leone considered the species to be a protector of the home of their ancestral spirits. This rockfowl is considered one of Africa's most desirable birds by birders and is a symbol of ecotourism across its range. (Full article...)

  Condor #534 soaring over the Grand Canyon, U.S.

  
  The California condor (Gymnogyps californianus) is a New World vulture and the largest North American land bird. It became extinct in the wild in 1987 when all remaining wild individuals were captured, but has since been reintroduced to northern Arizona and southern Utah (including the Grand Canyon area and Zion National Park), the coastal mountains of California, and northern Baja California in Mexico. It is the only surviving member of the genus Gymnogyps, although four extinct members of the genus are also known. The species is listed by the International Union for the Conservation of Nature as Critically Endangered, and similarly considered Critically Imperiled by NatureServe.
  
  The plumage is black with patches of white on the underside of the wings; the head is largely bald, with skin color ranging from gray on young birds to yellow and bright orange on breeding adults. Its 3.0 m (9.8 ft) wingspan is the widest of any North American bird, and its weight of up to 12 kg (26 lb) nearly equals that of the trumpeter swan, the heaviest among native North American bird species. The condor is a scavenger and eats large amounts of carrion. It is one of the world's longest-living birds, with a lifespan of up to 60 years.
  
  Condor numbers dramatically declined in the 20th century due to agricultural chemicals (DDT), poaching, lead poisoning, and habitat destruction. A conservation plan put in place by the United States government led to the capture of all the remaining wild condors by 1987, with a total population of 27 individuals. These surviving birds were bred at the San Diego Wild Animal Park and the Los Angeles Zoo. Numbers rose through captive breeding, and beginning in 1991, condors were reintroduced into the wild. Since then, their population has grown, but the California condor remains one of the world's rarest bird species. By 31 December 2022, the National Park Service gave a total world population of 561. A 2023 estimation of a population of 558 is provided by the non-profit Ventana Wildlife Society on their website. The condor is a significant bird to many Californian Native American groups and plays an important role in several of their traditional myths. (Full article...)

  Jynx ruficollis ruficollis in South Africa

  
  The red-throated wryneck (Jynx ruficollis), also known as the rufous-necked wryneck or red-breasted wryneck, is a species of wryneck in the woodpecker family closely related to the Eurasian wryneck. Its three subspecies are resident in much of sub-Saharan Africa in open habitats with some trees. It is a slim, elongated bird about 19 cm (7.5 in) in length, with a small head, fine bill, long fan-shaped tail and cryptic plumage intricately patterned in greys and browns. The sexes look similar, although males are slightly larger. The diet of the adults and young is almost entirely ants at all stages of their life cycles. The call of the red-throated wryneck is a series of repeated harsh, shrill notes. When threatened, a bird will twist its neck and head in a snake-like manner while making a hissing sound, presumably to deter predators.
  
  The red-throated wryneck nests in pre-existing holes, usually in trees, preferring old barbet or woodpecker nests. The unlined nest cavity is usually 3–4 m (10–13 ft) above the ground, and the clutch is typically three or four white eggs, laid at one-day intervals. Both sexes incubate the eggs for 12–15 days until the blind, naked chicks hatch. The chicks are fed by both adults for 25–26 days until they fledge. There are usually two broods. The red-throated wryneck has a very extensive range, and its population is large and increasing. For this reason, it is evaluated as a species of least concern by the International Union for Conservation of Nature (IUCN). (Full article...)

  Male in breeding plumage

  
  The variegated fairywren (Malurus lamberti) is a fairywren that lives in eastern Australia. As a species that exhibits sexual dimorphism, the brightly coloured breeding male has chestnut shoulders and azure crown and ear coverts, while non-breeding males, females and juveniles have predominantly grey-brown plumage, although females of two subspecies have mainly blue-grey plumage.
  
  Like other fairywrens, the variegated fairywren is a cooperative breeding species, with small groups of birds maintaining and defending small territories year-round. Groups consist of a socially monogamous pair with several helper birds who assist in raising the young. Male wrens pluck yellow petals and display them to females as part of a courtship display. These birds are primarily insectivorous and forage and live in the shelter of scrubby vegetation east of the Great Dividing Range. Populations across central, northern and western Australia were considered subspecies of this species until 2018, when they were reclassified as the purple-backed fairywren. (Full article...)

  Adult male S. c. carolinensis in Green-Wood Cemetery, New York, USA

  
  The white-breasted nuthatch (Sitta carolinensis) is a species of bird in the nuthatch family Sittidae. It is a medium-sized nuthatch, measuring approximately 15.5 cm (6.1 in) in length. Coloration varies somewhat along the species' range, but the upperparts are light blue-gray, with a black crown and nape in males, while females have a dark gray crown. The underparts are whitish, with a reddish tinge on the lower abdomen. Despite not being closely related, the white-breasted nuthatch and the white wagtail are very similar in plumage. The white-breasted nuthatch is a noisy bird. It has a nasal voice and often utters little cries or vocalizations, often composed of repetitions of small invariant whistles. In summer, it is an exclusively insectivorous bird, consuming a wide range of arthropods, but in winter its diet consists mainly of seeds. The nest is located in the cavity of a tree. The clutch consists of five to nine eggs, incubated for two weeks by the female, who is fed by the male. The two adults then feed the young until they fledge, and for a few weeks after that.
  
  The white-breasted nuthatch breeds throughout much of North America, except in the cooler and drier areas. It is mainly found at low elevations, in deciduous forests or in mixed woodlands. Seven to nine subspecies are generally distinguished by their slightly distinct distributions, vocalizations, and coloration. The species was once thought to be related to the white-cheeked nuthatch (S  leucopsis) and Przewalski's nuthatch (S. przewalskii), two species from southern Asia, but is actually more closely related to the giant nuthatch (S. magna), also from Southeast Asia. The species enjoys a very wide distribution and its population is said to be increasing; the International Union for the Conservation of Nature therefore considers it to be of "least concern."

  The red wattlebird (Anthochaera carunculata) is a passerine bird native to southern Australia. At 33–37 cm (13–14+1⁄2 in) in length, it is the second largest species of Australian honeyeater. It has mainly grey-brown plumage, with red eyes, distinctive pinkish-red wattles on either side of the neck, white streaks on the chest and a large bright yellow patch on the lower belly. The sexes are similar in plumage. Juveniles have less prominent wattles and browner eyes. John White described the red wattlebird in 1790. Three subspecies are recognized.
  
  The species is found in southeast Queensland, New South Wales, Victoria, South Australia and southwest Western Australia in open forest and woodlands, and is a common visitor to urban gardens and parks. Loud and conspicuous, the red wattlebird is generally found in trees, where it gets most of its food; occasionally it forages on the ground. It is one of the largest nectarivorous birds in the world, feeding from a wide variety of flowering plants. Insects also comprise part of its diet. It is territorial and at times aggressive towards birds of other species, often defending rich sources of nectar. Breeding throughout its range, the red wattlebird builds a cup-shaped nest in a tree and raises one or two broods a year. Although it has declined in places from land-clearing, it is classified as Least Concern on the IUCN Red List. (Full article...)

  The corn crake, corncrake or landrail (Crex crex) is a bird in the rail family. It breeds in Europe and Asia as far east as western China, and migrates to Africa for the Northern Hemisphere's winter. It is a medium-sized crake with buff- or grey-streaked brownish-black upperparts, chestnut markings on the wings, and blue-grey underparts with rust-coloured and white bars on the flanks and undertail. The strong bill is flesh-toned, the iris is pale brown, and the legs and feet are pale grey. Juveniles are similar in plumage to adults, and downy chicks are black, as with all rails. There are no subspecies, although individuals from the east of the breeding range tend to be slightly paler than their western counterparts. The male's call is a loud krek krek, from which the scientific name is derived. The corn crake is larger than its closest relative, the African crake, which shares its wintering range; that species is also darker-plumaged, and has a plainer face.
  
  The corn crake's breeding habitat is grassland, particularly hayfields, and it uses similar environments on the wintering grounds. This secretive species builds a nest of grass leaves in a hollow in the ground and lays 6–14 cream-coloured eggs which are covered with rufous blotches. These hatch in 19–20 days, and the black precocial chicks fledge after about five weeks. This crake is in steep decline across much of its former breeding range because modern farming practices often destroy nests before breeding is completed. The corn crake is omnivorous but mainly feeds on invertebrates, the occasional small frog or mammal, and plant material including grass seed and cereal grain. Threats include dogs, cats, other introduced and feral mammals, large birds, various parasites and diseases.
  
  Although numbers have declined steeply in western Europe, this bird is classed as least concern on the IUCN Red List because of its huge range and large, apparently stable, populations in Russia and Kazakhstan. Numbers in western China are more significant than previously thought, and conservation measures have facilitated an increased population in some countries which had suffered the greatest losses. Despite its elusive nature, the loud call has ensured the corn crake has been noted in literature, and garnered a range of local and dialect names. (Full article...)

  A male in Wamboin, NSW, Australia

  
  The yellow-tailed black cockatoo (Zanda funerea) is a large cockatoo native to the south-east of Australia measuring 55–65 cm (22–26 in) in length. It has a short crest on the top of its head. Its plumage is mostly brownish black and it has prominent yellow cheek patches and a yellow tail band. The body feathers are edged with yellow giving a scalloped appearance. The adult male has a black beak and pinkish-red eye-rings, and the female has a bone-coloured beak and grey eye-rings. In flight, yellow-tailed black cockatoos flap deeply and slowly, with a peculiar heavy fluid motion. Their loud, wailing calls carry for long distances. The yellow-tailed black cockatoo is found in temperate forests and forested areas across south and central eastern Queensland to southeastern South Australia, including a very small population persisting in the Eyre Peninsula. Two subspecies are recognised, although Tasmanian and southern mainland populations of the southern subspecies xanthanotus may be distinct enough from each other to bring the total to three. Birds of subspecies funereus (Queensland to eastern Victoria) have longer wings and tails and darker plumage overall, while those of xanthanotus (western Victoria, South Australia and Tasmania) have more prominent scalloping.
  The subspecies whiteae is found south of Victoria to the East of South Australia and is smaller in size.
  
  The yellow-tailed black cockatoo's diet primarily includes seeds of native and introduced plants while also feeding on wood-boring grubs. They nest in large hollows high in old growth native trees (~ greater than 200 years old), generally Eucalyptus regnans. Although they remain common throughout much of their range, fragmentation of habitat and loss of large trees suitable for nesting has caused population decline in Victoria and South Australia. Furthermore, the species may lose most of its mainland range due to climate change. In some places yellow-tailed black cockatoos appear to have partially adapted to recent human alteration of landscape and they can often be seen in parts of urban Canberra, Sydney, Adelaide and Melbourne. The species is not commonly seen in aviculture, especially outside Australia. Like most parrots, it is protected by CITES, an international agreement that makes trade, export, and import of listed wild-caught species illegal. (Full article...)

Selected general bird topic

A top of broken glass provides an effective physical deterrent to birds considering resting on this wall.

Bird control or bird abatement involves the methods to eliminate or deter pest birds from landing, roosting and nesting.

Bird control is important because pest birds can create health-related problems through their feces, including histoplasmosis, cryptococcosis, and psittacosis. Bird droppings may also cause damage to property and equipment. Birds also frequently steal from crops and fruit orchards. (Full article...)

Selected taxon

Great eared nightjar

Nightjars are medium-sized nocturnal or crepuscular birds in the family Caprimulgidae /ˌkæprɪˈmʌldʒɪdiː/ and order Caprimulgiformes, characterised by long wings, short legs, and very short bills. They are sometimes called goatsuckers, due to the ancient folk tale that they sucked the milk from goats (the Latin for goatsucker is caprimulgus), or bugeaters, their primary source of food being insects. Some New World species are called nighthawks. The English word "nightjar" originally referred to the European nightjar.

Nightjars are found all around the world, with the exception of Antarctica, and certain island groups such as the Seychelles. They can be found in a variety of habitats, most commonly the open country with some vegetation. They usually nest on the ground, with a habit of resting and roosting on roads.

The subfamilies of nightjars have similar characteristics, including small feet, of little use for walking, and long, pointed wings. Typical nightjars have rictal bristles, longer bills, and softer plumage. The colour of their plumage and their unusual perching habits help conceal them during the day. (Full article...)

  The tropical kingbird (Tyrannus melancholicus) is a large tyrant flycatcher, growing to a length of about 22 cm (8.7 in). It feeds on insects, either catching them in flight, or gleaning them from the surface of foliage, and also eats some fruit. The birds remain in pairs all year round, and drive intruders from their territories, including birds much larger than them. It nests high in trees, usually in the fork of a branch, building a bulky, untidy structure. The female incubates the typical clutch of two to four eggs and the young fledge in about 18 days. Its breeding range extends from the southern United States to central Argentina, with birds near the northern and southern limits of the range being migratory. This picture shows a T. m. melancholicus individual in the Pantanal, Brazil.

Selected bird anatomy topic

Common gallinule in Brazil

A frontal shield, also known as a facial shield or frontal plate, is a feature of the anatomy of several bird species. Located just above the upper mandible, and protruding along the forehead, it is composed of two main parts: a hard, proteinaceous callus and a soft, fleshy corium. It is thought to play roles in protection, mate identification, sexual selection, and territorial defense. (Full article...)

Selected species

The turkey vulture, Cathartes aura, also known in North America as the turkey buzzard, is a bird found throughout most of the Americas. One of three species in the genus Cathartes, in the family Cathartidae, it is the most common of the New World vultures, ranging from southern Canada to the southernmost tip of South America. It inhabits a variety of open and semi-open areas. It has dark brown to black plumage, a featherless, purplish-red head and neck, and a short, hooked, ivory-colored beak. It is a scavenger and feeds almost exclusively on carrion. It finds its meals using its sense of smell, flying low enough to detect the gases produced by the beginnings of the process of decay in dead animals. In flight, it uses thermals to move through the air, flapping its wings only infrequently. Lacking a syrinx—the vocal organ of birds—its only vocalizations are grunts or low hisses. It nests in caves, hollow trees, or thickets, generally raising two chicks each year, which it feeds by regurgitation.
