Size:
These birds are 13-15 cm long and have a wingspan of 20-23 cm. They weigh 9-11 g.
Habitat:
The American dusky flycatcher breeds in temperate forests and scrublands, including coniferous, deciduous and mixed forests. During winter they are found in tropical and sub-tropical dry forests and scrublands. They are present at altitudes of 650-3.000 m.
Diet:

Breeding:
American dusky flycatchers breed in May-August. The nest is a cup made of grasses, weeds and shreds of bark, lined with plant down, feathers, animal hair, and other soft materials. It is placed is a vertical fork in a scrub or small tree, 1-5 m above the ground. The female lays 2-4 white eggs, rarely with brownish flecks, which she incubates alone for 15-16 days. The chicks are fed by both parents and fledge 15-20 days after hatching, but continue to be fed by the parents for another 3 weeks. Each pair raises a single clutch per year.
Conservation:
IUCN status – LC (Least Concern)
This species has a large breeding range and in Canada de population was estimated at 0,5-5 million individulas. The global population had a stable trend over the last 4 decades so this species is not considered threatened.
