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.
Common Blackbird
The common blackbird is one of Europe's most familiar and best-loved songbirds, celebrated for its rich, fluting song delivered from rooftop and treetop perches at dawn and dusk. Originally a shy woodland bird, it has colonized urban environments over the past two centuries and become one of the most successful urban adapters.
