The red-necked crake (Rallina tricolor) is a waterbird in the rail and crake family, Rallidae.
The red-necked crake is a large crake (length 25 cm, wingspan 40 cm, weight 200 g). Its head, neck and breast are red-brown, with a paler version of that color on the throat. The upperparts are grey-brown, while the underparts are grey-brown with pale barring. The underwing is barred black and white, the bill green, and the legs grey-brown.
Red-necked crakes live in the Moluccas, Lesser Sundas, New Guinea lowlands and adjacent islands, and north-eastern Australia. They are found in tropical rainforests and dense vegetation close to permanent wetlands.
The bird's diet consists of amphibians, aquatic invertebrates, crustaceans and molluscs.
The bird rests on or close to ground in dense vegetation. It lays clutches of 3-5 dull-white eggs, the incubation periods of which are around 20 days. The chicks emerge covered in black down, precocial and nidifugous.
The crake makes repetitive clicking calls and soft grunts.
With a large range and no evidence of significant decline, this species is assessed as being of least concern. The species is little studied and seldom seen due to its secretive nature, but appears to be locally common in New Guinea. In Australia it has suffered declines due to habitat loss.
The Caspian tern is a species of tern, with a subcosmopolitan but scattered distribution. Despite its extensive range, it is monotypic of its genus, and has no accepted subspecies. The genus name is from Ancient Greek hudros, "water", and Latin progne, "swallow". The specific caspia is from Latin and, like the English name, refers to the Caspian Sea.
The white-headed duck is a small diving duck some 45 cm (18 in) long. The male has a white head with black crown, a blue bill, and reddish-grey plumage. The female has a dark bill and rather duller colouring. Its breeding habitat is lakes with open water and dense vegetation at the margin. It dives under water and feeds on aquatic vegetation as well as some animal matter. It is more likely to swim away from a perceived threat than to fly. This duck is known from Spain, North Africa, Western Asia and Central Asia. Populations are declining, mostly due to loss of habitat and pollution, and the International Union for Conservation of Nature has rated the bird's status as "endangered".
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 red-capped plover, also known as the red-capped dotterel, is a small species of plover.
The oriental plover, also known as the oriental dotterel, is a medium-sized plover closely related to the Caspian plover. It breeds in parts of Mongolia and China, migrating southwards each year to spend its non-breeding season in Indonesia, New Guinea and northern Australia.
The tambourine dove is a pigeon which is a widespread resident breeding bird in woodlands and other thick vegetation in Africa south of the Sahara Desert. Its range extends from Senegal east to Ethiopia and Kenya and southwards through eastern Africa to south-eastern South Africa, but it is absent from the drier areas of south-western Africa. There is a population on the Comoros Islands.
The African crake is a small- to medium-size ground-living bird in the rail family, found in most of central to southern Africa. It is seasonally common in most of its range other than the rainforests and areas that have low annual rainfall. This crake is a partial migrant, moving away from the equator as soon as the rains provide sufficient grass cover to allow it to breed elsewhere. There have been a few records of vagrant birds reaching Atlantic islands. This species nests in a wide variety of grassland types, and agricultural land with tall crops may also be used.
The red-legged crake is a waterbird in the rail and crake family, Rallidae.
The starred wood quail is a species of bird in the family Odontophoridae. It is found in subtropical or tropical moist lowland forests of Bolivia, Brazil, Ecuador, and Peru.
The black crake is a waterbird in the rail and crake family, Rallidae. It breeds in most of sub-Saharan Africa except in very arid areas. It undertakes some seasonal movements in those parts of its range which are subject to drought. No subspecies have been described. It appears that the oldest available name for this species is actually Rallus niger J. F. Gmelin, 1788, but Swainson believed that the earlier name was unidentifiable, and his own has since become well embedded in the literature.
The white-bellied imperial pigeon is a species of bird in the pigeon family Columbidae. First described by the French ornithologist Charles Lucien Bonaparte in 1854, it is endemic to Indonesia, where it is found on Sulawesi, Buton, Taliabu, Togian, and Peleng. It inhabits primary forest, dense secondary forest, and isolated areas of hill forest. A large pigeon with a long tail, it measures 42.5–51.5 cm (16.7–20.3 in) long and weighs 510 g (18 oz) on average. Males are mainly green, with pale-grey heads and bellies, chestnut vents, and a pale grey tail band, along with a red orbital ring. Females are nearly identical, but have darker grey areas in their plumage.
The pale-vented bush-hen is a medium sized waterbird, mainly blue-grey with a buff vent and undertail. It is found in Australia, the Moluccan Islands, New Guinea, the Bismarck Archipelago and the Solomon Islands. Its natural habitat is subtropical or tropical moist lowland forests.
The Okinawa rail is a species of bird in the rail family, Rallidae. It is endemic to Okinawa Island in Japan where it is known as the Yanbaru kuina. Its existence was only confirmed in 1978 and it was formally described in 1981 although unidentified rails had been recorded on the island since at least 1973 and local stories of a bird known as the agachi kumira may refer to this species.
The Australian crake , also known as Australian spotted crake, or spotted crake is a species of bird in the family Rallidae. It is one of three species of Australian crakes in the genus Porzana, the others being the spotless crake and Baillon’s crake.
The spotless crake is a species of bird in the rail family, Rallidae. It is widely distributed species occurring from the Philippines, New Guinea and Australia, across the southern Pacific Ocean to the Marquesas Islands and south to New Zealand.
The Andaman crake is a bird species in the family Rallidae. It is endemic to the Andaman Islands of the eastern Indian Ocean.
The red-chested buttonquail is a species of bird in the family Turnicidae. It is endemic to Australia. The species is generally regarded as widespread, although uncommon, in New South Wales, Queensland, northern Western Australia and the Northern Territory, and classified as Vulnerable in Victoria.
The white-bellied cuckooshrike is a species of bird in the family Campephagidae. It is found in Australia, the Moluccas, New Guinea and the Solomon Islands.
The Aztec thrush is a species of bird in the family Turdidae. It is found mainly in Mexico, but vagrants are occasionally seen in the United States. Its natural habitat is montane forests. The IUCN Red List denotes it as a least-concern species.
