Reischek's Parakeet
Cyanoramphus hochstetteri
A medium-sized, emerald-green parakeet endemic to the Antipodes Islands, including smaller outer islands. Recognized by its distinctive bright red crown and small red patches behind the eyes. Green body plumage has a slight yellowish tint. Males are larger than females. Most commonly found in areas of low vegetation and open areas along the coast. Forms small flocks in autumn and winter. Calls are a distinctive parakeet chatter. Distinguished from Red-crowned Parakeet by lack of range overlap and the more yellow-green body plumage. Easily distinguished from larger, all-green Antipodes Island Parakeet.
分类信息
The common name commemorates pioneering naturalist and collector Andreas Reischek, who collected specimens of the parrot in 1888 and who named it Platycercus hochstetteri for the son of his friend, Austrian geologist Ferdinand von Hochstetter, who made a geological survey of New Zealand.<p>Reischek’s parakeet was previously considered to be a subspecies of the red-crowned parakeet C. novaezelandiae, which it resembles in appearance, but was later lumped with the Macquarie parakeet from Macquarie Island in a 2001 paper by Wee Ming Boon and others following an examination of the molecular systematics of the genus which found that many of the red-crowned parakeet subspecies should be elevated to full species. However, subsequently the provenance of Boon et al.’s supposed Macquarie Island material was shown to be mistaken, originating from the Antipodes Islands instead.

行为
Reischek’s parakeet feeds on tussock flowers, leaves, seeds, berries as well as invertebrates such as fly larvae in the guano of the penguin colonies. It also scavenges on the carcasses of petrels and albatrosses.
保护状况
Though the population of Reischek's parakeet is healthy, its limited distribution makes it potentially vulnerable to events such as the accidental introduction of rodents to its island home. On the New Zealand Threatened Species classification it is listed as ‘range restricted’.

Maroon Pigeon
Columba thomensis
A large, very dark pigeon with a grayish head, a burgundy body with scattered small white spots, and a bright yellow bill and legs. Female is duller than the male. A scarce species found singly and in pairs in the canopy of primary and secondary forest, more frequently above 1300 meters of elevation; attends fruiting trees. Mostly quiet and inconspicuous, but gives a rolling, growling “crrr-crrow-rrrow-rrrow-rrrow” and other low-pitched pigeon-like cooing. Smaller Sao Tome Pigeon has a gray breast and an iridescent green nape and lacks Maroon Pigeon’s yellow feet and bill.
Palm-nut Vulture
Gypohierax angolensis
Small, odd, distinctive vulture. Adults are boldly patterned black-and-white, with red bare facial skin. Juveniles are brown. Immature birds show a mixture of juvenile and adult traits. Distinctive shape in flight: broad, paddle-shaped wings and a short, wide tail. Found in a variety of habitats, including forest, woodland, and savanna--usually in the vicinity of palms. Somewhat similar to African Fish-Eagle, but easily separated by red facial skin and different pattern of black and white. Juveniles are similar to Hooded Vulture, but are smaller, with a thicker bill.
Long-billed Partridge
Rhizothera longirostris
Strange-looking and little-known partridge with a distinctive, faintly-hooked, dark bill. Male has a brownish-orange head and gray neck and chest. Female has a rusty-brown head and neck. Found in lowland and foothill forest; generally uncommon and patchy throughout range. Secretive, foraging quietly on the forest floor, rarely emerging into the open. Gives a loud, echoing “weeweew”.
