The alder flycatcher is a plain little bird that is dull green in color with a whitish belly. It has a light eye ring and two whitish wing bars. By sight, it is indistinguishable from the willow flycatcher but can be identified by voice and breeding habitat.
Habitat and Habits
Alder flycatchers inhabit wet thickets and damp, brushy fields. They prefer wetter haunts than the willow flycatcher, and they are often found in high quality wetlands, such as fens. Alders give an explosive upslurred three-beers! as their song, and the call is a flat peep, which is slightly suggestive of the call note of the olive-sided flycatcher.
Reproduction and Care of the Young
The nest is a loose cup of grass with little or no plant down, and is placed in a low bush or sapling.
