About These Birds
American Robin
The American robin is widely regarded as a harbinger of spring across North America. Despite its name, it is a true thrush unrelated to the European robin. American robins produce two to three broods per year and are among the earliest birds to sing in the morning chorus.
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.
