- Empidonax occidentalis
Identification
A small (14cm, 5.5in) flycatcher of typical appearance; back brownish-olive, yellowish-olive underparts, two strong buff-colored wing bars, crest, and white-eye-ring, slightly extended behind the eye.
Similar Species
- Pacific-slope Flycatcher: physically indistinguishable except by voice in the males.
- Yellow-bellied Flycatcher: has shorter tail than E. occidentalis, and brighter, more yellow wing bars.
Distribution
Breeding: in Canada found Alberta and probably British Columbia; through intermountain west of the USA, most commonly in Idaho, Wyoming, Utah, Colorado, Arizona, and New Mexico, and in a more spotted distribution in Washington, Nevada and California; in Mexico in highlands down to the Isthmus (but not in Baja California).
Leaves Canada, the USA and the northern part of its Mexican range in winter, and in that period is found down to the Pacific Coast.
Taxonomy
Cordilleran Flycatcher and Pacific-slope Flycatcher were in the past considered one species, Western Flycatcher.
Subspecies
There are 2 subspecies[1]:
- E. o. hellmayri:
- E. o. occidentalis:
- Highlands of Mexico
Habitat
Shaded forests, often along streams; especially in Mexico prefers high elevation habitat for breeding.
Behaviour
Perches on a branch, sallying forth repeatedly to catch flying insects.
