| Genera | |
The Recurvirostridae are a family of birds in the wader suborder Charadrii. It contains two distinct groups of birds, the avocets (one genus) and the stilts (two genera).
Avocets and stilts range in length from 30 to 46 cm (12 to 18 in) and in weight from 140 to 435 g (4.9 to 15.3 oz); males are usually slightly bigger than females. [1] All possess long, thin legs, necks, and bills. The bills of avocets are curved upwards, and are swept from side to side when the bird is feeding in the brackish or saline wetlands they prefer. The bills of stilts, in contrast, are straight. The front toes are webbed, partially in most stilts, and fully in avocets and the banded stilt, which swim more. [1] The majority of species' plumage has contrasting areas of black and white, with some species having patches of buff or brown on the head or chest. [2] The sexes are similar. [1]
Their vocalizations are usually yelps of one or two syllables. [1]
Avocets and stilts are a cosmopolitan family, being distributed on all the world's continents except Antarctica, and occurring on several oceanic islands. Several species are wide-ranging and a few are locally distributed.
One species, the black stilt of New Zealand, is critically endangered due to habitat loss, introduced predators, and hybridisation with the pied stilt.
These species feed on small aquatic animals such as mollusks, brine shrimp and other crustaceans, larval insects, segmented worms, tadpoles, and small fish.
Stilts and avocets breed on open ground near water, often in loose colonies. They defend nesting territories vigorously with aggressive displays, and mob intruders and possible predators with a great deal of noise. [1] They are monogamous, although the pair bonds are not maintained from season to season. Their eggs are light-coloured with dark markings, weighing 22 to 44 g (0.78 to 1.55 oz). [1] Three to four are laid in simple nests, and both parents share the incubation duties, which last 22 to 28 days. [1] The banded stilt may breed only every few years, as it breeds on temporary lakes caused by rains in the deserts of Australia. The chicks are downy and precocial, leaving the nest within a day of hatching; [1] they fledge in 28 to 35 days. [1] In all species except the banded stilt, the chicks are cared for by the parents for several months, and they may move them to new areas and defend territories there. [1] Banded stilts deviate from this by collecting their chicks in massive crèches numbering several hundred.
The taxonomy of the stilts is particularly debated, with the genus Himantopus considered to have two to six species.

Cuckoos are birds in the Cuculidae family, the sole taxon in the order Cuculiformes. The cuckoo family includes the common or European cuckoo, roadrunners, koels, malkohas, couas, coucals, and anis. The coucals and anis are sometimes separated as distinct families, the Centropodidae and Crotophagidae, respectively. The cuckoo order Cuculiformes is one of three that make up the Otidimorphae, the other two being the turacos and the bustards. The family Cuculidae contains 150 species, which are divided into 33 genera.
Stilt is a common name for several species of birds in the family Recurvirostridae, which also includes those known as avocets. They are found in brackish or saline wetlands in warm or hot climates.
The antbirds are a large passerine bird family, Thamnophilidae, found across subtropical and tropical Central and South America, from Mexico to Argentina. There are more than 230 species, known variously as antshrikes, antwrens, antvireos, fire-eyes, bare-eyes and bushbirds. They are related to the antthrushes and antpittas, the tapaculos, the gnateaters and the ovenbirds. Despite some species' common names, this family is not closely related to the wrens, vireos or shrikes.
The American avocet is a large wader in the avocet and stilt family, Recurvirostridae, found in North America. It spends much of its time foraging in shallow water or on mud flats, often sweeping its bill from side to side in water as it seeks crustacean and insect prey.
The black-winged stilt is a widely-distributed, very long-legged wader in the avocet and stilt family Recurvirostridae. Its scientific name, Himantopus himantopus, is sometimes used to generalize a single, almost cosmopolitan species. Alternatively, it is restricted to the form that is widespread in Europe, Asia and Africa, which equals the nominate group of H. himantopussensu lato. Meanwhile, the black-necked and white-backed stilts both inhabit the Americas; the pied stilt ranges from Australasia and New Zealand. Today, most sources accept between one and four actual species. The taxonomic name Himantopus comes from Greek, meaning "strap-foot" or "thong-foot".
The killdeer 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 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 Pacific golden plover is a migratory shorebird that breeds during Alaska and Siberia summers. During nonbreeding season, this medium-sized plover migrates widely across the Pacific.
The pigeon guillemot 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.
The pied avocet is a large black and white wader in the avocet and stilt family, Recurvirostridae. They breed in temperate Europe and across the Palearctic to Central Asia then on to the Russian Far East. It is a migratory species and most winter in Africa or southern Asia. Some remain to winter in the mildest parts of their range, for example in southern Spain and southern England. The pied avocet is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.
The snowy plover is a small wader in the plover bird family, typically about 5-7" in length. It breeds in the southern and western United States, the Caribbean, Ecuador, Peru, and Chile. Long considered to be a subspecies of the Kentish plover, it is now known to be a distinct species.
The white-breasted nuthatch 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 African jacana is a wader in the family Jacanidae. It has long toes and long claws that enables it to walk on floating vegetation in shallow lakes, its preferred habitat. It is widely distributed in sub-Saharan Africa. For the origin and pronunciation of the name, see Jacanidae.
The banded stilt is a nomadic wader of the stilt and avocet family, Recurvirostridae, native to Australia. It belongs to the monotypic genus Cladorhynchus. It gets its name from the red-brown breast band found on breeding adults, though this is mottled or entirely absent in non-breeding adults and juveniles. Its remaining plumage is pied and the eyes are dark brown. Nestling banded stilts have white down, unlike any other species of wader.
The black stilt or kakī (Māori) is a wading bird found in New Zealand. It is one of the world's rarest birds, with 169 adults surviving in the wild as of May 2020. Adult kakī have distinctive black plumage, long pink legs, and a long thin black bill. Black stilts largely breed in the Mackenzie Basin in the South Island, and are threatened by introduced feral cats, ferrets, and hedgehogs as well as habitat degradation from hydroelectric dams, agriculture, and invasive weeds.
Harris's sparrow is a large sparrow. Their breeding habitat is the north part of central Canada, making it Canada's only endemic breeding bird. In the winter they migrate to the Great Plains states of the United States, from southern South Dakota to central Texas. The common name of this species commemorates the American amateur ornithologist Edward Harris (1799–1863).
The red-necked avocet also known as the Australian avocet, cobbler, cobbler's awl, and painted lady, is a wader of the family Recurvirostridae that is endemic to Australia and is fairly common and widespread throughout, except for the north and north east coastal areas of the country. Closely related to the stilts, it shares their fragile slender elegance, however the deep red head and neck distinguish them. It appeared on a 13 cent postage stamp in 1966.
The rainbow pitta 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.
The Andean avocet is a large wader in the avocet and stilt bird family, Recurvirostridae. It is resident in the Andes, breeding above 3500 m in northwestern Argentina, western Bolivia, northern Chile and southern Peru.
The pied stilt, also known as the white-headed stilt, is a shorebird in the family Recurvirostridae. It is widely distributed with a large total population size and apparently stable population trend, occurring in Malaysia, Japan, the Philippines, Brunei, Christmas Island, Indonesia, Palau, Papua New Guinea, Australia, and New Zealand. It is listed as Least Concern on the IUCN Red List. It is sometimes considered a subspecies of the black-winged stilt.
The black-necked stilt is a locally abundant shorebird of American wetlands and coastlines. It is found from the coastal areas of California through much of the interior western United States and along the Gulf of Mexico as far east as Florida, then south through Central America and the Caribbean to Brazil, Peru and the Galápagos Islands, with an isolated population, the Hawaiian stilt, in Hawaii. The northernmost populations, particularly those from inland, are migratory, wintering from the extreme south of the United States to southern Mexico, rarely as far south as Costa Rica; on the Baja California peninsula it is only found regularly in winter. Some authorities, including the IUCN, treat it as a subspecies of Himantopus himantopus.
