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 Pygmy-tyrant
The Black-capped Pygmy-tyrant is one of the world's smallest passerines, a tiny tyrant flycatcher of Central and South American humid forests, with a conspicuous black cap, olive-green upperparts, and yellowish underparts. It inhabits the mid-story and canopy of lowland and foothill tropical forests from Costa Rica to Bolivia and Brazil. It feeds on tiny insects, gleaning them from fine foliage.
