Hooded Parrot
Psephotellus dissimilis
A slender and long-tailed parrot restricted to a relatively small range in the Northern Territory, where it inhabits open woodlands. Male a striking turquoise color with black cap, yellow wings, rosy undertail coverts, and olive back. Female primarily pale green with turquoise underparts except for rosy undertail coverts. Slenderer and longer-tailed than Red-winged Parrot and Northern Rosella, with bright yellow shoulders obvious in flight. This species digs tunnels in termite mounds in order to breed. Calls include a sharp "chit."
识别特征
The hooded parrot is a medium-sized parrot, up to 26 cm long, weighing 50 to 60 g. The male has a black head, bluish-grey beak, dark-brown irises, and its wings have a yellow patch. Its upper-parts are brown, its lower parts are turquoise blue, its back is brown, the tail is olive green tipped pale blue, and its legs are pink-grey. The female is a dull-green parrot with a grey-brown head and pink undertail coverts. Juveniles are similar to the female.<p>The male hooded parrot can be distinguished from the similar looking male golden-shouldered parrot mainly by the absence of a pale frontal band, a larger yellow patch on the wings, and absence of the red on the abdomen. The female is very similar to the female Yellow-shouldered parrot being identified by the absence of a pale frontal band and an absence of red on the abdomen.
分类信息
One of three species known as antbed parrots, the hooded parrot is closely related to (and sometimes considered a subspecies of) the golden-shouldered parrot (Psephotellus chrysopterygius). A genetic study revealed its ancestors most likely diverged from ancestors of the latter species in the late Miocene or early Pliocene at the conclusion of the 'Hill Gap'.<p>Norwegian naturalist Robert Collett described the hooded parrot in 1898. Its species name is the Latin word dissimilis "different" and either refers to its sexual dimorphism or its different appearance from its closest relative. Black-hooded parrot is an alternative name.

分布与栖息地
An Australian endemic, the hooded parrot inhabits to semi-arid areas of northeast Northern Territory, and is separated from the golden-shouldered parrot by the Carpentarian faunal barrier.<p>Though this species has disappeared from most of its original range, it remains common in protected areas. The hooded parrot is evaluated as Least Concern on IUCN Red List of Threatened Species.

Red-headed Vulture
Sarcogyps calvus
A dark, medium-sized vulture with a bare reddish head and loose flaps on the side of the neck. Juvenile is browner with scruffy, pale feathers on the head. In flight, the species has narrow wings and appears dark overall with contrasting white patches on the flanks and a white line running through the wing. Inhabits dry forests and adjacent areas. Shy and solitary compared to other vultures in the region.
Javan White-eye
Zosterops flavus
Little bright yellow bird found in southern Borneo and northern Java. Entirely yellow coloration (no dark lores or gray belly) distinguishes this species from other white-eyes within its range. A coastal forest specialist, found in coastal scrub forest, mangroves, and forest edge, as well as adjacent gardens and plantations, where it often visits planted langsat (or duku) trees. Often found on small offshore islands. Forages actively in the canopy, giving quiet tweeting and cheeping calls; unlike other white-eyes, not a strong songster. Declining across much of range due to habitat destruction and fragmentation.
Ringed Antpipit
Corythopis torquatus
Small ground-dwelling flycatcher of lowland rainforest. Very unusual appearance for a flycatcher, looking more like a tiny thrush or an antbird as it struts around the ground with its body held upright. Likes to walk on logs and tree roots in mature rainforest, making short flights up to understory vegetation to catch insects. Dull brown above and white below with broad black breast streaks. Listen for its short song with a distinctive “up-down” pattern, a whistled “wheeu, pew.”
