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.

Taxonomy

The pale-yellow robin was first described by ornithologist John Gould in 1854. [2] 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. [3] 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. [4]

Description

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. [4] It can be distinguished from the eastern yellow robin, as the latter bird has black legs and is a little larger. [7]

The pale-yellow robin makes a trilling call when displaying or defending its territory.

Distribution and habitat

Sedentary in its range, the pale-yellow robin is found from Mount Amos to Paluma in North Queensland, and from Cooloola on the Sunshine Coast south to Barrington Tops National Park in New South Wales. It prefers rainforest or dense eucalypt forest, particularly where the lawyer vine grows. [4]

Behaviour

The pale-yellow robin is arboreal and secretive. It is predominantly insectivorous, though may supplement its diet with seeds. [7]

Breeding

It uses the prickly lawyer vine ( Calamus muelleri) as nesting material and as a nest site. [8] 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. [9]

Australasian robin Family of birds

The bird family Petroicidae includes 49 species in 19 genera. All are endemic to Australasia: New Guinea, Australia, New Zealand and numerous Pacific Islands as far east as Samoa. For want of an accurate common name, the family is often called the Australasian robins. Within the family species are known variously as robins, scrub-robins and flyrobins. They are only distantly related to the European robin of Europe, north Africa and western Asia, a member of family Muscicapidae.

Flame robin A small passerine bird native to southeastern Australia

The flame robin is a small passerine bird native to Australia. It is a moderately common resident of the coolest parts of south-eastern Australia, including Tasmania. Like the other two red-breasted Petroica robins—the scarlet robin and the red-capped robin—it is often simply called the robin redbreast. Like many brightly coloured robins of the Petroicidae, it is sexually dimorphic. Measuring 12–14 cm (4.7–5.5 in) long, the flame robin has dark brown eyes and a small thin black bill. The male has a brilliant orange-red chest and throat, and a white patch on the forehead above the bill. Its upper parts are iron-grey with white bars, and its tail black with white tips. Female coloration is a muted grey-brown. Its song has been described as the most musical of its genus.

Restless flycatcher Species of bird

The restless flycatcher, or restless myiagra, is a passerine bird in the family Monarchidae; it is also known as the razor grinder or scissors grinder because of its distinctive call. It is a native of eastern and southern Australia. Populations in New Guinea and northern Australia, which were at one time considered to be a subspecies, are now accepted as a separate species, the paperbark flycatcher. It is a small to medium-sized bird and has similar colouring to the willie wagtail.

Eastern whipbird Species of bird

The eastern whipbird is an insectivorous passerine bird native to the east coast of Australia. Its whip-crack song is a familiar sound in forests of eastern Australia. Two subspecies are recognised. Heard much more often than seen, it is dark olive-green and black in colour with a distinctive white cheek patch and a crest. The male and female are similar in plumage.

Red-capped robin A small passerine bird native to Australia

The red-capped robin is a small passerine bird native to Australia. Found in drier regions across much of the continent, it inhabits scrub and open woodland. Like many brightly coloured robins of the family Petroicidae, it is sexually dimorphic. Measuring 10.5–12.5 cm (4.1–4.9 in) in length, the robin has a small, thin, black bill, and dark brown eyes and legs. The male has a distinctive red cap and red breast, black upperparts, and a black tail with white tips. The underparts and shoulders are white. The female is an undistinguished grey-brown. This species uses a variety of songs, and males generally sing to advertise territories and attract females. Birds are encountered in pairs or small groups, but the social behaviour has been little studied.

<i>Eopsaltria</i> Genus of birds

Eopsaltria is a genus of small forest passerines known in Australia as the yellow robins. They belong to the Australasian robin family Petroicidae. The name is derived from the Ancient Greek for "dawn singer/song" because of their dawn chorus. They are inquisitive and bold birds, and have been reported perching on the shoulders or boots of people in the bush. Open eucalyptus woodlands are their preferred habitat. The ornithologist John Gould likened the behaviour and mannerisms of the eastern and western yellow robin to those of the European robin. The name "yellow robin" itself was applied to the eastern yellow robin by the early settlers of New South Wales.

White-breasted robin Species of songbird native to southwestern Australia

The White-breasted Robin is a passerine bird in the Australasian robin family Petroicidae and the Yellow Robin genus Eopsaltria. Occasionally it is placed in the genus Quoyornis. It is endemic to southwestern Australia. Unlike many other Australian robins, it lacks bright colours in its plumage, being a predominantly greyish bird with white underparts. Like other closely related Australasian robins, it is a cooperative breeder. It is sedentary, with pairs or small groups maintaining territories.

Western yellow robin Species of songbird native to southern Australia

The western yellow robin is a species of bird in the Australasian robin family, Petroicidae, native to Australia. Described by John Gould in 1838, the western yellow robin and its Australian relatives are not closely related to either the European or American robins, but they appear to be an early offshoot of the Passerida group of songbirds. Ranging between 13.5 and 15.5 cm long, it has grey upperparts, and a grey breast and head, broken by whitish streaks near the bill and below the eye, with a conspicuous yellow belly. The sexes are similar in appearance. Two subspecies are recognized: subspecies griseogularis, which has a yellow rump, and subspecies rosinae with an olive-green rump.

Pink robin Species of songbird native to southeastern Australia

The pink robin is a small passerine bird native to southeastern Australia. Its natural habitats are cool temperate forests of far southeastern Australia. Like many brightly coloured robins of the family Petroicidae, it is sexually dimorphic. Measuring 13.5 cm (5.3 in) in length, the robin has a small, thin, black bill, and dark brown eyes and legs. The male has a distinctive white forehead spot and pink breast, with grey-black upperparts, wings and tail. The belly is white. The female has grey-brown plumage. The position of the pink robin and its Australian relatives on the passerine family tree is unclear; the Petroicidae are not closely related to either the European or American robins, but appear to be an early offshoot of the Passerida group of songbirds.

Pacific robin Species of songbird native to islands in southwestern Pacific

The Pacific robin, is a red-breasted Australasian robin in the passerine bird genus Petroica found in Melanesia and Polynesia. It is similar in plumage to the scarlet robin of Australia, and until recently the two were considered conspecific until split in 1999 by Schodde and Mason. Thirteen subspecies of Pacific robin are currently recognised, and these subspecies display considerable variation in plumage, foraging preferences, and habitat. The Norfolk robin was previously considered a subspecies of the Pacific robin, but is now considered a distinct species.
