Pale-yellow Robin
Eopsaltria capito
A rotund little robin, olive above, with gray head, yellow underparts, and white around the base of the bill. Perches on low branches and on the side of tree trunks, from which it drops to the ground to capture prey. Similar Eastern Yellow Robin is brighter yellow below and has gray lores. Inhabits rainforests in the wet tropics of far northern Queensland and eastern Australia.
识别特征
The male and female pale-yellow robin are similar in plumage. Measuring 12–13.5 centimetres (4.7–5.3 in) and weighing 15–18 grams (0.53–0.63 oz), it is a bird of subdued appearance, with grey head and nape blending into olive-green upperparts, more brownish on the wings and tail. The throat is white, and the lores are off-white in the southern race and buff in the northern race. The breast and belly are yellow. The legs are yellow-orange and the iris dark brown. The thin black bill is around 1.5 centimetres (0.59 in) long. Juvenile birds are rufous with paler streaks on the head. It can be distinguished from the eastern yellow robin, as the latter bird has black legs and is a little larger.<p>The pale-yellow robin makes a trilling call when displaying or defending its territory.
分类信息
The pale-yellow robin was first described by ornithologist John Gould in 1854. For many years, it was classified with the other yellow robins in the genus Eopsaltria, on the basis of plumage, nests, and behaviour. Others have placed it with the genus Poecilodryas, due to the similarly plumaged fledglings. However, the closest relatives of both it and the related white-faced robin remain unclear, and are hence placed in their own small genus Tregellasia, originally erected by Gregory Mathews in 1912. Like all Australian robins, it is not closely related to either the European robin or the American robin, but belongs rather to the Corvida parvorder, comprising many tropical and Australian passerines, including pardalotes, fairy-wrens and honeyeaters, as well as crows.<p>Alternate common names given to the species have been large-headed robin and pale robin.

分布与栖息地

行为
The pale-yellow robin is arboreal and secretive. It is predominantly insectivorous, though may supplement its diet with seeds.<p>It uses the prickly lawyer vine (Calamus muelleri) as nesting material and as a nest site. The nest may be anywhere up to 10 m (30 ft) above the ground, though often much lower. Breeding season is July to December with one, or sometimes two, broods. A clutch of 2 oval eggs, measuring 20 by 15 millimetres (0.79 in × 0.59 in), is laid. They are pale green, splotched with brownish marks.

Green-backed White-eye
Zosterops xanthochroa
A classic small greenish-yellow white-eye species with bold white eye-rings. Common in more humid habitats throughout New Caledonia; mostly replaced by Silvereye in drier and more disturbed areas, though the two can be found together. Green-backed is plainer overall than Silverye, without any contrasting plumage apart from the eyering. Has a typical white-eye vocal repertoire, with a high-pitched wheezy warbling song and high-pitched piercing quavering call notes.
Grasshopper Buzzard
Butastur rufipennis
A small, slim, fairly long-tailed buzzard. Gray and brown on the upperparts and rufous on the underparts. The white throat has a black line down the center. In flight, reveals distinctive rufous patches on the tops of the wings, with mostly white underwings. Found in a variety of savanna and grassland habitats. A migratory species that is often found in flocks, especially near fires. Best told from other buzzards by its structure, and in flight by its rufous wing panels. The call is a series of “ki” notes.
