The scrubtit (Acanthornis magna) is a species of bird in the thornbill family Acanthizidae. It is endemic to Tasmania and King Island in Australia. Its natural habitat is the temperate rainforest, Nothofagus beech forest and eucalypt woodland. It is a small species that resembles the Sericornis scrubwrens (with which it was once placed).
The scrubtit belongs to the monotypic genus Acanthornis. [3] A 2017 genetic study using both mitochondrial and nuclear DNA found the ancestor of the scrubtit diverged from that of the three whitefaces of the genus Aphelocephala around 7 million years ago. The combined lineage had diverged from the thornbill lineage around 13 million years ago. [4]
The scrubtit is 11 to 12 centimetres (4.33 to 4.72 in) long and weighs around 10 grams (0.35 oz). The plumage consists of a white throat and belly, a brown back, crown, flank and tail, black wings and grey on the face. The eye is pale and the bill is short, black and slightly curved. The species is often silent, but makes quite loud contact calls and has a song described as "sweet [and] musical".
The scrubtit forages individually, in pairs or in small family groups near the ground in dense cover. It feeds on small invertebrates, particularly insects and their eggs. The species will associate with mixed-species feeding flocks. The species is territorial and monogamous, with the breeding season lasting from September to January. The nest is a woven globe with a side entrance, lined with feathers and fur, camouflaged and usually found between 1–3 m off the ground. The clutch size is usually three eggs but sometimes four. The eggs measure 18 by 15 millimetres (0.71 by 0.59 in) and are pearly white, with fine reddish spots, mostly around the larger end. [5] No information exists about incubation or nestling times. Both parents feed the chicks in the nest, but unlike many Australian passerines helpers have never been reported. [6] The species is victim to brood parasitism by fan-tailed cuckoos (Cacomantis flabelliformis) and shining bronze-cuckoos (Chrysococcyx lucidus), and quolls (Dasyurus) also take eggs and nestlings. [7] The species is shy and unobtrusive and is seldom observed by people.[ citation needed ]
The species has a restricted range but is not considered threatened by the IUCN. The subspecies found on King Island (A. m. greeniana) is considered critically endangered, however.[ citation needed ] A 2018 study ranked this subspecies third as the Australian bird most likely to go extinct. [8]
The spotted flycatcher is a small passerine bird in the Old World flycatcher family. It breeds in most of Europe and in the Palearctic to Siberia, and is migratory, wintering in Africa and south western Asia. It is declining in parts of its range.
The brown thornbill is a passerine bird usually found in eastern and south-eastern Australia, including Tasmania. It can grow up to 10 cm (3.9 in) long, and feeds on insects. It is brown, grey and white. The species has five subspecies.
The rifleman is a small insectivorous passerine bird that is endemic to New Zealand. It belongs to the family Acanthisittidae, also known as the New Zealand wrens, of which it is one of only two surviving species. The rifleman resembles a wren in form, but is not related to the family of true wrens, Troglodytidae, nor the fairy-wrens of Australia.
The yellow-rumped thornbill is a species of passerine bird from the genus Acanthiza. The genus was once placed in the family Pardalotidae but that family was split and it is now in the family Acanthizidae. There are four subspecies of yellow-rumped thornbill. It is a small, brownish bird with a distinctive yellow rump and thin dark bill. It inhabits savannah, scrub and forests across most of Australia and eats insects. The species engages in cooperative breeding.
The scarlet robin is a common red-breasted Australasian robin in the passerine bird genus Petroica. The species is found on continental Australia and its offshore islands, including Tasmania. The species was originally split in 1999 by Schodde and Mason, and as the original collection by Gmelin was from Norfolk Island, this retained the name of multicolor, and is now known as the Norfolk robin.
The yellow-faced honeyeater is a small to medium-sized bird in the honeyeater family, Meliphagidae. It takes its common and scientific names from the distinctive yellow stripes on the sides of its head. Its loud, clear call often begins twenty or thirty minutes before dawn. It is widespread across eastern and southeastern Australia, in open sclerophyll forests from coastal dunes to high-altitude subalpine areas, and woodlands along creeks and rivers. Comparatively short-billed for a honeyeater, it is thought to have adapted to a diet of flies, spiders, and beetles, as well as nectar and pollen from the flowers of plants, such as Banksia and Grevillea, and soft fruits. It catches insects in flight as well as gleaning them from the foliage of trees and shrubs.
The weebill is a species of bird in the family Acanthizidae. It is an insectivorous passerine that is found throughout mainland Australia. At 8 to 9 cm long, it is Australia's smallest bird. It was originally described by John Gould in 1838, and four subspecies are recognised. The weebill's plumage is nondescript, with olive-grey upperparts and paler, more yellowish underparts. It grades from more brownish plumage in the southern regions of Australia to more yellow in tropical areas.
The rainbow pitta is a small passerine bird in the pitta family, Pittidae, endemic to northern Australia, most closely related to the superb pitta of Manus Island. It has a velvet black head with chestnut stripes above the eyes, olive green upper parts, black underparts, a bright red belly and an olive green tail. An Australian endemic, it lives in the monsoon forests and in some drier eucalypt forests.
The buff-rumped thornbill is a small passerine bird species belonging to the genus Acanthiza, most of which are endemic to Australia. Measuring 8–10 cm in length, this unassuming thornbill is characterised by its plain greenish brown upperparts and very pale-yellow underparts, with a distinctive buff coloured rump. The tail has a broad, blackish band with a paler tip. Adults possess white irises, whilst juveniles have dark eyes. The buff-rumped thornbill is one of 14 species within the genus Acanthiza genus, which are recognisable by their thin, pointed bill. Species are unique in their plumage and distribution. Despite their shared name, the genus is not related to hummingbirds.
The inland thornbill was originally described by English ornithologist John Gould in The Birds of Australia. Inland thornbills are within the order passerines. The inland thornbill belongs to the genus Acanthiza, which now has three more species than the eleven outlined by Gould in The Birds of Australia. The Noongar people of southwestern Western Australia call A. apicalis "Djoobi-Djoolbang". The inland thornbill is also known as the broad-tail thornbill and presently contains several subspecies that were once considered independent species. The word apicalis comes from the Latin for 'tipped'.
The shining bronze cuckoo is a species of cuckoo in the family Cuculidae, found in Australia, Indonesia, New Caledonia, New Zealand, Papua New Guinea, Solomon Islands, and Vanuatu. It was previously also known as Chalcites lucidus.
The striated thornbill is a species of bird in the family Acanthizidae. It is endemic to Australia, where its natural habitat is subtropical or tropical dry forests.
The rufous fieldwren also known as the desert wren or sandplain wren is a species of insectivorous bird in the family Acanthizidae, endemic to Australia.
The bristlebirds are a family of passerine birds, Dasyornithidae. There are three species in one genus, Dasyornis. The family is endemic to the south-east coast and south-west corner of Australia. The genus Dasyornis was sometimes placed in the Acanthizidae or, as a subfamily, Dasyornithinae, along with the Acanthizinae and Pardalotinae, within an expanded Pardalotidae, before being elevated to full family level by Christidis & Boles (2008).
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.
The goldenface is a species of passerine bird endemic to New Guinea. It is the only species (monotypic) within the genus Pachycare.
The pilotbird is a species of passerine bird in the family Acanthizidae. It is monotypic within the genus Pycnoptilus. The species is endemic to south-eastern Australia.
The large-billed scrubwren is a passerine bird in the family Acanthizidae, endemic to eastern Australia. It is found in denser undergrowth in temperate forest, subtropical or tropical moist lowland forest, and subtropical or tropical moist montane forest.
Acanthizidae—sometimes called Australian warblers—are a family of passerine birds which includes gerygones, thornbills Acanthiza, and scrubwrens Sericornis. The family Acanthizidae consists of small to medium passerine birds, with a total length varying between 8 and 19 centimetres. They have short rounded wings, slender bills, long legs, and a short tail. Most species have olive, grey, or brown plumage, although some have patches of a brighter yellow. The weebill is the smallest species of acanthizid, and the smallest Australian passerine; the largest is the pilotbird.
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.
