6" (15 cm). Olive green above, whitish or sometimes yellow below (especially on flanks and belly), with distinct white eye ring. Identified chiefly by voice and habitat. Juvenile similar to adult, but wingbars buffy and body feathers with buffy edges.
An emphatic 2-note flee-see or peet-seet! with the second syllable accented and higher pitched, uttered on the breeding grounds and occasionally on migration.
Beech and maple or hemlock forests, usually under the canopy but also in clearings; often in wooded ravines.
Breeds from southern Minnesota east through southern New England, south to Gulf Coast and central Florida. Winters in tropics.
The Acadian Flycatcher and its relatives in the genus Empidonax are difficult to distinguish visually, but in much of the South the Acadian is the only breeding species; between June and August, any Empidonax seen in the lowlands south of New Jersey and Missouri can safely be called an Acadian.
3 or 4 brown-spotted buff eggs in a woven nest of plant fibers in a bush or tree, usually over a stream.
