Similar species

Hammond's Flycatcher differs most obviously in its longer primary projection, also slightly darker breast and smaller bill; although usually seen in tall conifers, on migration Hammond's can occur with Dusky in lower scrub. Gray Flycatcher has longer bill with dark tip. Gray dips tail down like a phoebe while Dusky pumps tail up.

Distribution

North and Central America
Breeds western North America from central British Columbia south to California, Arizona and New Mexico; winters to southern Mexico.

Taxonomy

This is a monotypic species[1].

Formerly sometimes treated as a subspecies of Gray Flycatcher as Empidonax wrightii oberholseri, though the two are not particularly closely related within the genus[2].

Habitat

Scrub, brushland, thickets, open low coniferous forests, and mountain chaparral. Unlike Hammond's Flycatcher, not in tall, dense conifers except at the edges of open areas or where where tree spacing is more open.

Behaviour

Diet

The diet includes insects.

Breeding

The nest is cupshaped.
