The yellow thornbill, formerly known as the little thornbill, is a tiny passerine bird endemic to the eastern coast of Australia. While currently listed as Least Concern by the IUCN, the general consensus is that the population is decreasing.
Acanthiza is a genus of passeriform birds, most endemic to Australia, but with two species restricted to New Guinea. These birds are commonly known as thornbills. They are not closely related to species in the hummingbird genera Chalcostigma and Ramphomicron, which are also called thornbills.
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 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 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 western thornbill is a species of bird in the family Acanthizidae. It is endemic to southwestern Australia.
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 New Guinea thornbill or Papuan thornbill is a species of bird in the family Acanthizidae. It is found in the New Guinea Highlands.
The speckled warbler is a species of bird in the family Acanthizidae. It is endemic to eastern Australia. Its natural habitat is temperate forests.
The grey honeyeater is a species of bird in the honeyeater family. It is an uncommon and little-known bird, an often overlooked endemic of remote areas in central Australia.
The yellow-bellied gerygone is a species of bird in the family Acanthizidae. It is found in New Guinea. Its natural habitat is subtropical or tropical moist lowland forests.
The fan-tailed gerygone is a species of bird in the family Acanthizidae. It is found in New Caledonia and Vanuatu. The Rennell gerygone of the Solomon Islands was formerly considered conspecific, but was split as a distinct species by the IOC in 2021.
The Lord Howe gerygone or Lord Howe gerygone flyeater was a small bird in the family Acanthizidae, brown and greyish in color. Its head was brown apart from a pale grey eye-ring and a grey throat and chin, many parts of the animal varied to the colour of yellow, this being apparent in its bright yellow belly. It made its home in the canopies of the island's forest until the early 20th century. The bird has had a variety of monikers: locally, it was known as the "rain-bird" due to its activity after the rains, or the "pop-goes-the-weasel", due to the similarity of its song to the well-known tune. The bird was endemic to Lord Howe Island in the Tasman Sea. There have been no records of the species since 1928, and it is considered to be extinct. Its extinction is almost certainly due to predation by black rats which were accidentally introduced to the island in 1918 following the shipwreck of the SS Makambo there.
The mangrove gerygone is a species of bird in the Australian warbler family Acanthizidae. The species is also known as the mangrove warbler. The species is thought to form a superspecies with the closely related fan-tailed gerygone of Melanesia and the Australian western gerygone. There are three subspecies of mangrove gerygone, G. l. pallida, found in southern New Guinea, the nominate race G. l. levigaster, which is found from coastal Western Australia to coastal north Queensland, and G. l. cantator, which is found from coastal Queensland to New South Wales. The species is uncommon in New Guinea and has suffered some declines due to mangrove clearances but is not considered threatened by the IUCN.
The fairy gerygone, previously known as the fairy warbler, is a species of bird in the family Acanthizidae native to New Guinea and Queensland.
The brown-breasted gerygone or treefern gerygone is a species of bird in the family Acanthizidae. It is found in the highlands of New Guinea. Its natural habitat is subtropical or tropical moist montane forests.
The golden-bellied gerygone is a species of bird in the family Acanthizidae. It is found in Brunei, Indonesia, Malaysia, the Philippines, Singapore, and Thailand. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical mangrove 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.
