Taxonomy and systematics
Formerly, the three species have been considered conspecific, but all major authorities now consider them as separate species.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.

Three species are recognized:Description
They are strongly sexually dimorphic, with males having olive-green upperparts, a black head, and (uniquely for the family) distinct bright red facial skin.Simpson, K. (editor) & N. Day (illustrator) (1994). ''Field Guide to the Birds of Australia.'' 2nd edition. Christopher Helm. Coates, B. J., & K. D. Bishop (1997). ''A Guide to the Birds of Wallacea.'' Dove Publications Pty. Ltd. Females are drab-coloured, being dull brownish above, and white below with strong dark streaking. They have greyish facial skin, and a greyish-black bill.Behaviour and ecology
Compared to the "typical" Old World orioles of the genus '' Oriolus'', the figbirds are more frugivorous (though they also take some small insects, nectar, and seeds) and gregarious, even breeding in small, loose colonies (at least for the Australasian figbird; the nesting habits are still unknown for the other two species).References
