Description of the Alder Flycatcher
© Greg Lavaty.
The Alder Flycatcher is greenish above, with white eye rings and two whitish wing bars. The underside of its bill is mostly yellow.
Seasonal change in appearance
Very little, although wing bars are narrower in the fall.
Juveniles have buffier wing bars than adults.
Moist willow and alder thickets.
Alder Flycatchers fly out from a perch to capture insects in flight, or pick them off of vegetation while hovering.
Alder Flycatchers breed widely over the northeastern U.S. and most of southern Canada. They winter in South America.
The Alder Flycatcher is so similar to the Willow Flycatcher, neither of which vocalizes on the wintering grounds, that determining the winter ranges of the two species was and is difficult.
Late to arrive on breeding grounds and quick to depart, the Alder Flycatcher’s breeding season is short.
The typical song is a “fee-BEE-o” with the accent on the second syllable.
