The pink-backed pelican (Pelecanus rufescens) is a bird of the pelican family. It is a resident breeder in the swamps and shallow lakes of Africa and southern Arabia; it has also apparently been extirpated from Madagascar.
The pink-backed pelican was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae . He placed it with the other pelicans in the genus Pelecanus and coined the binomial name Pelecanus rufescens. [2] Gmelin based his description on the "red-backed pelican" that had been described in 1785 by the English ornithologist John Latham in his multi-volume work A General Synopsis of Birds . Latham had been sent a specimen from West Africa. [3] [4] The specific epithet rufescens is Latin for "reddish". [5] The species is monotypic: no subspecies are recognised. [6]
It is a relatively small pelican, although by no means is it a small bird. Its length is from 125 to 155 cm (49 to 61 in), wingspan is 2.15–2.9 m (7.1–9.5 ft) and body mass is from 4 to 7 kg (8.8 to 15.4 lb). The bill is 30 to 38 cm (12 to 15 in) in length. [7] [8] The plumage is grey and white, with a pinkish hue on the back occasionally apparent (never in the deep pink of a flamingo). The top of the bill is yellow and the pouch is usually greyish. Breeding adults have long feather plumes on the head.
It shares its habitat with the great white pelican, which is generally larger and has white instead of greyish plumage.
The pink-backed pelican is found in a range of aquatic habitats, but prefers quiet backwaters with shallow water, avoiding steep, vegetated lake banks. It prefers for freshwater lakes, swamps, large slow-flowing rivers, and seasonal pools but also frequents reservoirs, seasonally flooded land and flood-plains near river mouths. It may occur on alkaline and saline lakes and lagoons, and can sometimes be found along the coast in bays and estuaries (although seldom on open seashore). The species tends to roost and breed in trees (e.g. mangroves), but will also roost on sandy islands, cliffs, coral reefs and sand-dunes.
Nesting trees have many nests built close together. These nests are re-used every year until the trees collapse, although the birds will normally remain in the area. The species nests colonially in trees, reeds or low bushes along waterfronts as well as (less often) on the ground on sandy islands and in mangroves.
Its nest is a large heap of sticks and may be 10–50 m above the ground. The female lays two to three large white eggs and later the chicks feed by plunging their heads deep into the adult's pouch and taking the partially digested regurgitated fish.
Food is usually fish (of any size up to 450 g, usually in the 80-290 g range) and amphibians, and is usually obtained by fishing in groups. Among the fish preyed upon are cichlids like Haplochromis and Tilapia .
The American white pelican is a large aquatic soaring bird from the order Pelecaniformes. It breeds in interior North America, moving south and to the coasts, as far as Costa Rica, in winter.
The greater yellowlegs is a large shorebird in the family Scolopacidae. It breeds in central Canada and southern Alaska and winters in southern North America, Central America, the West Indies and South America.
The lesser yellowlegs is a medium-sized shorebird. It breeds in the boreal forest region of North America.
The great white pelican also known as the eastern white pelican, rosy pelican or simply white pelican is a bird in the pelican family. It breeds from southeastern Europe through Asia and Africa, in swamps and shallow lakes.
The two-barred crossbill or white-winged crossbill is a small passerine bird in the finch family Fringillidae. It breeds in the coniferous forests of North America and the Palearctic.
The Australian pied cormorant, also known as the pied cormorant, pied shag, or great pied cormorant, is a medium-sized member of the cormorant family. It is found around the coasts of Australasia. In New Zealand, it is usually known either as the pied shag or by its Māori name of kāruhiruhi. Older sources may refer to it as the "yellow-faced cormorant".
The clapper rail is a member of the rail family, Rallidae. The taxonomy for this species is confusing and still being determined. It is a large brown rail that is resident in wetlands along the Atlantic coasts of the eastern United States, eastern Mexico and some Caribbean islands. This species was formerly considered to be conspecific with the mangrove rail.
The spot-billed pelican or gray pelican is a member of the pelican family. It breeds in southern Asia from southern Iran across India east to Indonesia. It is a bird of large inland and coastal waters, especially large lakes. At a distance they are difficult to differentiate from other pelicans in the region although it is smaller but at close range the spots on the upper mandible, the lack of bright colours and the greyer plumage are distinctive. In some areas these birds nest in large colonies close to human habitations.
The reed cormorant, also known as the long-tailed cormorant, is a bird in the cormorant family Phalacrocoracidae. It breeds in much of Africa south of the Sahara, and Madagascar. It is resident but undertakes some seasonal movements.
The reddish egret is a medium-sized heron that is a resident breeder in Central America, the Bahamas, the Caribbean, the Gulf Coast of the United States, and Mexico. The egret is known for its unusual foraging behavior compared to other herons as well as its association with mud flats, its habitat of choice.
The agami heron is a medium-sized heron. It is a resident breeding bird from Central America south to Peru and Brazil. It is sometimes known as the chestnut-bellied heron, and is the only member of the genus Agamia. In Brazil it is sometimes called Soco beija-flor, meaning 'hummingbird heron', thanks to its unique coloration pattern.
The Pacific reef heron, also known as the eastern reef heron or eastern reef egret, is a species of heron found throughout southern Asia and Oceania. It occurs in two colour morphs with either slaty grey or pure white plumage. The sexes are similar in appearance.
The nankeen night heron is a heron that belongs to the genus Nycticorax and the family Ardeidae. Due to its distinctive reddish-brown colour, it is also commonly referred to as the rufous night heron. It is primarily nocturnal and is observed in a broad range of habitats, including forests, meadows, shores, reefs, marshes, grasslands, and swamps. The species is 55 to 65 cm in length, with rich cinnamon upperparts and white underparts. The nankeen night heron has a stable population size, and is classified as a species of least concern by the International Union for Conservation of Nature (IUCN).
The wandering tattler, is a medium-sized wading bird. It is similar in appearance to the closely related gray-tailed tattler, T. brevipes. The tattlers are unique among the species of Tringa for having unpatterned, greyish wings and backs, and a scaly breast pattern extending more or less onto the belly in breeding plumage, in which both also have a rather prominent supercilium.
The red-faced cormorant, red-faced shag or violet shag, is a bird species of the family Phalacrocoracidae.
The red-winged parrot is a parrot native to Australia and New Guinea. It is found in grasslands, savannah, farmland, and woodland.
The rock shag, also known as the Magellanic cormorant, is a marine cormorant found around the southernmost coasts of South America. Its breeding range is from around Valdivia, Chile, south to Cape Horn and Tierra del Fuego, and north to Punta Tombo in Argentina. In winter it is seen further north, with individuals reaching as far as Santiago, Chile on the west coast and Uruguay on the east. The birds also breed around the coasts of the Falkland Islands.
The Antarctic tern is a seabird in the family Laridae. It ranges throughout the southern oceans and is found on small islands around Antarctica as well as on the shores of the mainland. Its diet consists primarily of small fish and crustaceans. It is very similar in appearance to the closely related Arctic tern, but it is stockier, and it is in its breeding plumage in the southern summer, when the Arctic tern has shed old feathers to get its non-breeding plumage. The Antarctic tern does not migrate like the Arctic tern does, but it can still be found on a very large range. This tern species is actually more closely related to the South American tern.
The New Zealand king shag, also known as the rough-faced shag, king shag or kawau tūī, is a rare bird endemic to New Zealand. Some taxonomic authorities, including the International Ornithologists' Union, place this species in the genus Leucocarbo. Others place it in the genus Phalacrocorax.
The African rail is a small wetland bird of the rail family that is found in eastern and southern Africa.
