January 20, 2017 - Cordilleran Flycatcher (Empidonax occidentalis)
These flycatchers are found in the western United States east of the Sierra Nevada and Cascade mountain ranges, as well as in central Mexico. Their diet is mostly small insects and other invertebrates, as well as some seeds and berries. Hunting from a perch, they chase and catch their prey in the air or pick it from foliage. Their nests are built in the forks of small trees, stumps, the roots of upturned trees, or sometimes in structures such as bridges. Females incubate the eggs and both parents feed the chicks. These birds are almost indistinguishable from their close relatives, Pacific-slope Flycatchers, and both were previously considered the same species, known as the Western Flycatcher. Slight differences in measurements and song are the only way to tell the two apart.
