Abstract
The alder flycatcher is a small flycatcher in the confusing genus Empidonax. It so closely resembles its look-alike congener, the willow flycatcher (E. traillii), that until 1973 they were considered a single species, Traill's flycatcher (American Ornithologists' Union 1973). As most published studies of Traill's Hycatcher have been of willow populations, relatively little is known about many aspects of alder behavior and ecology.
