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.
American Grey Flycatcher
The American Grey Flycatcher is a small empidonax weighing about 13 g with a 14.4 cm wingspan, breeding in dry sagebrush and pinyon-juniper habitat of the western United States. It characteristically dips its tail slowly downward, a behavior useful for identification.
