Acanthizidae

Acanthizidae is a family of passerine birds, sometimes called the Australian warblers, that includes the gerygones, thornbills and scrubwrens, comprising 67 species across 15 genera. Members are compact birds between about 8 and 19 centimeters long, with short rounded wings, slender bills, long legs and a short tail, mostly colored olive, grey or brown though some carry bright yellow patches. The family is found across Australia, which holds the greatest diversity with 35 endemic species, New Guinea with about 15 species, and smaller populations in Indonesia, New Zealand, Vanuatu, New Caledonia, the Solomon Islands and parts of Asia. Most acanthizids are terrestrial insect feeders that also take some seeds, and the family is notable for unusually long incubation periods, long lifespans of over a decade in the wild for many species, and cooperative breeding in some members.
