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.
Bearded Tachuri
The Bearded Tachuri is a near-threatened, tiny flycatcher of grasslands and open savannas in South America, from Colombia and Venezuela south to Argentina. Males have a bearded appearance with white throat streaking and rusty-brown plumage with a streaked breast. It inhabits tall native grasslands that are increasingly threatened by agriculture.
