Petroicidae

Petroicidae, the Australasian robins, is a family of passerine birds comprising 51 species in 19 genera, endemic to the Australasia region including New Guinea, Australia, New Zealand and Pacific islands as far east as Samoa. Members have a compact build with a large rounded head, a short straight bill and rounded wingtips, and occupy wooded habitats from alpine country to tropical rainforest. All species are primarily insectivorous and typically hunt by perching and pouncing on prey below, living in long-term pair bonds and small family groups, with many species practicing cooperative breeding. They build camouflaged cup-shaped nests, often set in a vertical fork of a tree or shrub and disguised with moss, bark or lichen; despite their common name, Australasian robins are only distantly related to the European robin, which belongs to the family Muscicapidae.
