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 the species are known not only as robins but as scrub-robins and flyrobins. They are, however, only distantly related to the Old World family Muscicapidae and the monarch flycatchers (Monarchidae).
The scrub robins or bush chats are medium-sized insectivorous birds in the genus Cercotrichas. They were formerly in the thrush family, (Turdidae), but are more often now treated as part of the Old World flycatcher family, (Muscicapidae). They are not closely related to the Australian scrub-robins, genus Drymodes in the family Petroicidae.
The eastern yellow robin is an Australasian robin of coastal and sub-coastal eastern Australia. The extent of the eastern yellow robin's residence is from the extreme southeast corner of South Australia through most of Victoria and the western half of New South Wales and north as far as Cooktown. Tropical Northern Queensland birds are mainly restricted to the warm heights of the Great Dividing Range.
The mountain robin, subalpine robin, alpine robin, or cloud-forest robin is a species of bird in the family Petroicidae. It is found sparsely throughout the New Guinea Highlands.
The southern scrub robin is a species of bird in the family Petroicidae. It is endemic to Australia, where it occurs in mallee and heathland in the semi-arid southern parts of the continent, extending from Wyperfeld National Park in Victoria in the east through South Australia to the west coast between Kalbarri and the Pinnacles in Nambung National Park.
Drymodes is a genus of bird in the family Petroicidae. It was traditionally held to have two species, but molecular and behavioural differences led to the split of the New Guinea populations from the northern scrub robin. The paper by Les Christidis and colleagues was published in 2011 and the IOC adopted the split in 2015:
The northern scrub robin is a species of bird in the family Petroicidae. It is found in northern Cape York Peninsula. It was found to be genetically distinct from the Papuan scrub robin, which were thought to be members of the same species.
The mangrove robin is a passerine bird in the family Petroicidae. It is found in the Aru Islands, New Guinea, and northern Australia. The bird's common name refers to its natural habitat. They live in mangrove forests and seldom fly outside these biomes.
The olive flyrobin is a species of bird in the Australasian robin family Petroicidae that is found in New Guinea. Its natural habitat is subtropical or tropical moist lowland forests.
The canary flyrobin, also known as the Papuan flycatcher, canary robin, canary flycatcher, or montane flycatcher, is a species of bird in the family Petroicidae. It is found in New Guinea. Its natural habitat is subtropical or tropical moist montane forests.
The island monarch is a species of bird in the family Monarchidae. It is found from Sulawesi to the Solomon Islands. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests.
The shining flycatcher is a species of bird in the family Monarchidae. It is found in northern Australia, and from the Moluccas to the Bismarck Archipelago. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical mangrove forest.
The broad-billed flycatcher is a species of bird in the family Monarchidae. It is found in northern Australia, the Lesser Sunda Islands and southern New Guinea. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical mangrove forest, and subtropical or tropical moist montane forest.
The white-rumped robin is a species of bird in the family Petroicidae. It is found in New Guinea. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests.
The slaty robin, also known as the blue-grey robin, is a species of bird in the family Petroicidae, present in the New Guinea Highlands and sparsely in the island's northern areas. Its natural habitat is subtropical or tropical moist montane forests.
The white-winged robin is a species of bird in the family Petroicidae.
The black-throated robin is a species of passerine bird in the Australisian robin family Petroicidae. It is found on the island of New Guinea. Its natural habitat is subtropical or tropical moist montane forests at 1,150–2,750 metres above sea-level.
The banded yellow robin or olive-yellow robin is a species of bird in the Australasian robin family Petroicidae that is found in New Guinea. It is the only species in the genus Gennaeodryas. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. It is threatened by habitat loss. It has a high mortality rate due to its inability to traverse across a matrix.
The Roper River scrub robin, also known as the allied scrub robin, is a putative subspecies of the northern scrub robin, a bird in the Petroicidae, or Australasian robin family. Whether it ever existed is doubtful; if it did it is almost certainly extinct.
The Vogelkop-Aru lowland rain forests is a tropical moist forest ecoregion in Indonesia. The ecoregion covers the peninsular lowlands of western New Guinea, along with the Aru Islands and other nearby islands.
