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-fronted Ground-tyrant
The Black-fronted Ground-tyrant is a small, pale gray flycatcher with a distinctive black forehead and crown contrasting against its otherwise plain gray-white body. It inhabits high-altitude rocky slopes, barren grasslands, and puna habitat in the Andes from Bolivia to northwestern Argentina, typically above 3,500 meters. It forages on the ground, running actively to catch insects and small invertebrates.
