About These Birds

Black-billed Nightingale-thrush

The Black-billed Nightingale-thrush is a small, secretive thrush of high-elevation oak and cloud forests in Costa Rica and western Panama, recognized by its dark bill, plain olive-brown upperparts, and washed orange-buff underparts. It inhabits the dense understory of montane forests above 1,500 meters. It feeds on insects, small fruits, and berries, foraging primarily on or near the ground.
