Tooth-billed Bowerbird

26-27 cm. Bill robust, dark brown, with serrations on cutting edge of both mandibles; eye dark red-brown; bare tan eye-ring. Plumage olive-brown above, fawn below, heavily streaked and mottled brown. Seldom seen or heard Feb.-July, but from c. Sept.-Jan., when males attend 'display courts', easily located by calls. Male occupies concealed song-perch 1-6 m above display court - a roughly oval cleared space 1-3 m in diameter, surrounding at least one tree trunk, and decorated with large leaves, picked green by bird chewing through leaf stem and usually laid pale underside uppermost. Perched bird produces stream of very loud song/mimicry (to this observer, seemingly louder/harsher than the originals). Also a softer sub-song of perfect mimicry: species mimicked include King Parrot, Crimson Rosella, Bower's Shrike-thrush, Mountain Thornbill, Bridled Honeyeater. When a female visits court, male drops to ground and displays, lunging forward or sideways with spread wings and twisting or flicking tail, wide open bill showing gleaming, white interior of tip to lower mandible, contrasting with black mouth-interior and spread fawn-white throat feathers. Outside breeding season, forages in rainforest canopy, singly or in small, loose companies, on fruit, insects, leaves, moving with planing glides between trees.
