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 Phoebe
The Black Phoebe is a medium-sized flycatcher with sooty-black plumage except for a white belly and vent, and a characteristic erect, upright posture. It is found throughout western North America south through Central and South America to Argentina, invariably near permanent water such as streams, ponds, and coastal areas. It feeds on flying insects caught in low, acrobatic sallies over water or ground.
