The Cordilleran Flycatcher
is yet another confusing Empidonax flycatcher, so much so that it and the almost
identical Pacific-slope Flycatcher
were once considered to be the same
species, called the "Western Flycatcher". They differ only in their
normal ranges, and in minor variations in voice. Females of the two species
are largely only identifiable by range. The Pacific-slope Flycatcher
is not found in South Dakota, however.
prefer deciduous forest in the mountains of the West, preferably along streams
and rivers. They will often forage in conifer groves, but aren't nearly as
common in pure conifer forests.
Diet: Feeds almost exclusively on insects. Also will eat
spiders, and occasionally berries and seeds.
Behavior: Often feeds in typical flycatcher
manner, watching from a perch and flying out to capture insects in mid-air.
They will feed at nearly any height in the forest canopy. They also
may glean food items from foliage, or capture insects from vegetation while
Nesting: June and July
Song: A broken pit-peet
song, with the 2nd note higher than the first.
Migration: Summers in and near mountains of the western United States and Mexico.
Winters in Mexico. The Black Hills of South
Dakota represent the furthest eastern extent of the species range.

as other Empidonax flycatchers.
Conservation Status: Appears to be stable throughout most of
