About These Birds
Alder Flycatcher
The Alder Flycatcher is a small North American flycatcher weighing about 13 g with a wingspan near 14 cm. It breeds in alder thickets and wet scrub across Canada and the northern United States, identified primarily by its distinctive fee-BEE-o song rather than its plain olive-grey plumage.
Black-capped Flycatcher
The Black-capped Flycatcher is a small Empidonax flycatcher restricted to highland forests in Costa Rica and western Panama, distinguished from similar species by its dark cap and pale eye ring. It inhabits the canopy and edges of cloud forests above 2,000 meters. It feeds on insects, sallying from perches in typical flycatcher fashion.
