The Magellanic oystercatcher (Haematopus leucopodus) is a species of wader in the family Haematopodidae. It is found in Argentina, Chile and the Falkland Islands in freshwater lake and sandy shore habitats.
The Magellanic oystercatcher has a length between 42 and 46 cm (17 and 18 in). The male weighs around 600 g (21 oz) and the female is a little heavier. [2] This bird has a long, orange beak, yellow eye and eye ring, and yellow legs. The head, breast, back, wings and tail are black and the underparts are white, as are the feathers on the inner part of the wing which can be seen in flight. It is very similar in appearance to the American oystercatcher (Haematopus palliatus), but can be distinguished by the yellow ring of bare skin that surrounds its yellow eye and the white secondary feathers. No other species of oystercatcher has these two features, and it is also the only New World species to have a black rather than a brown back. [3] The call is similar to other oystercatchers, a repeated high-pitched "pee-pee". [2]
This species is native to the southern tip of South America. Its range includes southern Argentina, Tierra del Fuego and other nearby islands, and the Falkland Islands. It is present on South Georgia and the South Sandwich Islands but its status there is unclear. [1] It breeds inland on upland grasslands but lives on the coast outside breeding season. [2]
When inland during breeding season, the Magellanic oystercatcher feeds largely on earthworms and insect larvae, probing soft ground and mud with its sharp beak. At other times of year when at the coast it forages for mussels and limpets and feeds on crabs and polychaete worms. [2]
When disturbed near the nest it engages in several strategies to divert attention from its eggs and chicks. These include false-brooding, when it moves to sit on an imaginary nest site, and tail-flagging, a ritual aggressive display involving raising tail and wings. It also has a distinctive peeping call to warn off intruders. [4]
The oystercatchers are a group of waders forming the family Haematopodidae, which has a single genus, Haematopus. They are found on coasts worldwide apart from the polar regions and some tropical regions of Africa and South East Asia. The exceptions to this are the Eurasian oystercatcher, the South Island oystercatcher, and the Magellanic oystercatcher, which also breed inland, far inland in some cases. In the past there has been a great deal of confusion as to the species limits, with discrete populations of all black oystercatchers being afforded specific status but pied oystercatchers being considered one single species.
The Eurasian oystercatcher also known as the common pied oystercatcher, or palaearctic oystercatcher, or just oystercatcher, is a wader in the oystercatcher bird family Haematopodidae. It is the most widespread of the oystercatchers, with three races breeding in western Europe, central Eurosiberia, Kamchatka, China, and the western coast of Korea. No other oystercatcher occurs within this area. The extinct Canary Islands oystercatcher, formerly considered a distinct species, may have actually been an isolated subspecies or distinct population of the Eurasian oystercatcher.
The kelp gull, also known as the Dominican gull, is a gull that breeds on coasts and islands through much of the Southern Hemisphere. The nominate L. d. dominicanus is the subspecies found around South America, parts of Australia, and New Zealand. L. d. vetula is a subspecies occurring around Southern Africa.
The black oystercatcher is a conspicuous black bird found on the shoreline of western North America. It ranges from the Aleutian Islands of Alaska to the coast of the Baja California peninsula.
The Fuegian steamer duck or the Magellanic flightless steamer duck, is a flightless duck native to South America. It belongs to the steamer duck genus Tachyeres. It inhabits the rocky coasts and coastal islands from southern Chile and Chiloé to Tierra del Fuego, switching to the adjacent sheltered bays and lakes further inland when breeding.
The Falkland steamer duck is a species of flightless duck found on the Falkland Islands in the South Atlantic Ocean. The steamer ducks get their name from their unconventional swimming behaviour in which they flap their wings and feet on the water in a motion reminiscent of an old paddle steamer. Interestingly, the Falkland steamer duck is one of only two bird species endemic to the Falkland Islands, the other being Cobb's wren.
The American oystercatcher, occasionally called the American pied oystercatcher, is a member of family Haematopodidae. Originally called the "sea pie", it was renamed in 1731 when naturalist Mark Catesby observed the bird eating oysters. The current population of American oystercatchers is estimated to be 43,000. There are estimated to be 1,500 breeding pairs along the Atlantic and Gulf Coasts of the US. The bird is marked by its black and white body and a long, thick orange beak.
The pied oystercatcher is a species of oystercatcher. It is a wading bird native to Australia and commonly found on its coastline. The similar South Island pied oystercatcher occurs in New Zealand.
The Chatham oystercatcher or Chatham Island oystercatcher is a species of oystercatcher. It is a wading bird endemic to the Chatham Islands, New Zealand. This species is rated by the IUCN as endangered, and has a current population of 310 to 325 birds. The main threat is from introduced predators.
The Canary Islands oystercatcher, Canarian oystercatcher, or Canarian black oystercatcher , was a shorebird of uncertain taxonomy endemic to Fuerteventura, Lanzarote, and their offshore islets in the Canary Islands, Spain. It is now considered to be extinct.
The white woodpecker is a South American species of woodpecker native to the wooded grasslands of Suriname, French Guiana, Brazil, Bolivia, Paraguay, Uruguay and Argentina. It is a bright white bird with black wings and a distinctive small bright yellow eye patch. The IUCN has rated it as a "least-concern species".
The blackish oystercatcher is a species of wading bird in the oystercatcher family Haematopodidae. It is found in Argentina, Chile, the Falkland Islands and Peru, and is a vagrant to Uruguay. The population is estimated at 15,000–80,000.
The variable oystercatcher is a species of wader in the family Haematopodidae. It is endemic to New Zealand. The Maori name is torea-pango. They are also known as 'red bills'.
Olrog's gull is a species of gull found along the Atlantic coast of southern Brazil, Uruguay, and northern Argentina. It was formerly considered a subspecies of the very similar L. belcheri. It is a large gull with a black back and wings, white head and underparts, a black band in the otherwise white tail, and a yellow bill with a red and black tip. Nonbreeding adults have a blackish head and a white eye ring. The species is named after Swedish-Argentine biologist Claes C. Olrog. It has a rather restricted breeding range and is threatened by habitat loss, and the IUCN has rated it as being "near threatened".
The brown-hooded gull is a species of gull found in Argentina, Brazil, Chile, the Falkland Islands, and Uruguay. Its specific epithet, maculipennis, means 'spotted wings'. It is a white bird with a brown head and red beak and feet.
The South American tern is a species of tern found in coastal regions of southern South America, including the Falkland Islands, ranging north to Peru and Brazil. It is generally the most common tern in its range. The smaller, highly migratory common tern closely resembles it. The specific epithet refers to the "swallow-like" forked tail feathering.
The Madagascar sandgrouse is a species of bird in the family Pteroclidae. It is endemic to Madagascar and is a ground-dwelling short-legged plump bird. The head of the male is brown with a black area surrounding the beak. He has a pinkish-buff coloured breast, a light brown mottled back, brown wings and paler underparts barred with dark brown. The female has a generally duller appearance being cryptically coloured brown with dark specks and bars.
The green iora is a species of bird in the family Aegithinidae. It is found in the Thai-Malay Peninsula, Sumatra and Borneo. Its habitats include lowland forests, secondary forest and mangrove forest. It is threatened by habitat loss, and the International Union for Conservation of Nature (IUCN) has assessed it as near-threatened.
The mottled piculet is a species of bird in the family Picidae. It is found in north eastern Argentina, south eastern Brazil, and Uruguay. Its natural habitat is subtropical or tropical moist lowland forests. It is becoming rare due to habitat loss.
