Tregellasia capito (Gould, 1852) |
The pale-yellow robin (Tregellasia capito) is a species of passerine bird in the family Petroicidae. It is endemic to eastern Australia. Its natural habitat is subtropical or tropical moist lowland forests. It is a nondescript bird with grey head and olive upperparts, white throat and yellow underparts. The sexes are similar. Two subspecies are recognised; the smaller nana from North Queensland and the larger and uncommon nominate race capito from southeast Queensland and northeastern New South Wales. It is insectivorous.
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.
Alternate common names given to the species have been large-headed robin and pale robin.
The male and female pale-yellow robin are similar in plumage. Measuring 12–13.5 cm (4¾–5⅓ in) and weighing 15–18 g, it is a bird of subdued appearance with grey head and nape blending into an olive green upperparts, more brownish on the wings and tail. The throat is white and the lores 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 cm (⅔ 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.
