The Australasian figbird (''Sphecotheres vieilloti'') is a conspicuous medium-sized passerine bird native to a wide range of wooded habitats in northern and eastern Australia, southern Papua New Guinea, and the Kai Islands in Indonesia.〔Higgins, P. J., L. Christidis, & H. A. Ford (2008). Family Oriolidae (Orioles). pp. 692-731 in: del Hoyo, J., A. Elliott, & D. A. Christie. eds. (2008). ''Handbook of the Birds of the World.'' Vol. 13. Pendulin-tits to Shrikes. Lynx Edicions. ISBN 978-84-96553-45-3〕 It was formerly considered a subspecies of ''S. viridis'', then simply referred to as the figbird (a name still commonly used in Australia, where the Australasian figbird is the only figbird). It is common in large parts of its range, and occurs in numerous protected areas. Consequently, it is rated as Least Concern by BirdLife International and the IUCN.〔 ==Taxonomy== Traditionally, all figbirds have been considered part of a single species, ''S. viridis'', but all recent major authorities recognize three species, the Australasian figbird (''S. viieilloti''), the Timor figbird (''S. viridis'') and the Wetar figbird.〔〔Dickinson, E.

ISBN 978-0-643-06511-6〕 The split is primarily based on differences in measurements and plumage, and on biogeography. Additionally, the Australasian figbird has sometimes been split into two separate species, the more northern, yellow figbird (''S. flaviventris'') and the green or southern figbird (''S. vieilloti''), but the two intergrade widely where they come into contact, supporting the view that they are part of a single biological species.〔 The Australasian figbird has five subspecies, in taxonomic order:〔〔 * ''S. v. cucullatus'' – Kai Islands in Indonesia. Possibly a junior synonym of ''S. v. flaviventris''.〔Clements, J. F. (2007). ''The Clements Checklist of the Birds of the World.'' 6th edition, w. updates. Christopher Helm.
