Plumbeous-backed Thrush

A fairly large pigeon of lowland and montane forest canopy with a pale gray head, breast, and back, a rufous belly, and spotted wings. The chest and belly colors blend in the female, but are separated by a black breast band in the male, the width of which varies with race. Occurs together with other imperial-pigeon species, but differs in having a rufous belly. Song is an accelerating series of deep hoots.

A tiny, brightly colored bird with a sharp bill. The back is olive-green, the wing blackish with white fringes, and the underparts yellow. Local and uncommon in savanna, ranging from moist Guinea savanna to dry thorn savanna. Usually in pairs or small flocks. Similar to Sennar and Forest Penduline-Tits, but much brighter: yellow rather than buffy below, and with white edges on the wing feathers. Vocalizations include a series of whistles in an up-and-down pattern and a quick series of buzzy notes. 

A medium-sized thrushlike bird of dense forests and undergrowth. The reddish brown coloration and white spectacles are distinctive. Usually skulks in dense vegetation, but may sing from an exposed perch or forage out in the open during dawn and dusk. Usually observed singly or in pairs. The song is loud, long, and varied, involving mimicry of other birds, whistles, and harsh notes that are often repeated. Introduced to Taiwan, Japan, and the Hawaiian Islands.
