The grey feathers on the head, neck and breast are brushed with paler grey-white and the wings are brownish. The legs and bill are black and the eyes brown or white.

Taxonomía

Originally described by ornithologist John Gould in 1837, its specific epithet is Latin cinerea "grey". In its own genus Struthidea, it is placed in the family known as the mud-nest builders or Corcoracidae, written as Grallinidae in older books before the removal of the genus Grallina to the monarch family. It is one of two remaining species, with the white-winged chough (Corcorax melanorhamphos), which differs in appearance but exhibits many behavioural similarities. The mudnest builder family Corcoracidae itself is now placed in a narrower "core corvine" group, which contains the crows and ravens, shrikes, birds of paradise, fantails, monarch flycatchers, and drongos.<p>The apostlebird was named after the Biblical apostles, the twelve followers of Jesus Christ. In fact, the species travel in family groups of between 6 and 20, which may coalesce with other family groups into large feeding flocks of over 40. Their gregarious nature, and harsh scolding/grating calls have led to a plethora of colloquial names. They can be known locally as lousy jacks (due to heavy louse infestations), happy jacks, and happy families. Grey jumper is an alternate name.

There is an isolated population in the Northern Territory. Dry open woodland is the preferred habitat, especially Callitris in New South Wales and Casuarina in Queensland, and Lancewood-Bulwaddi communities in the Northern Territory.
