The apostlebird (Struthidea cinerea), also known as the grey jumper, lousy jack, happy jack, Donny bird or caw bird is a quick-moving, gray or black bird about 33 cm long. It is a native to Australia where it roams woodlands, eating insects and seeds at, or near, ground level. Apostlebirds often travel in groups of about 12; for this reason, they were named after the 12 Biblical apostles.
Measuring around 33 cm in length, the apostlebird is a predominantly dark grey bird with a long black tail tinted greenish in sunlight. 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.
