- ORDER: Passeriformes
- FAMILY: Tyrannidae
Found mostly east of the Sierra Nevada and Cascade mountain ranges, the Cordilleran Flycatcher is a common small yellowish flycatcher of shaded forests. Nearly identical in appearance to the Pacific-slope Flycatcher, the two forms were formerly considered to be the same species, known as the "Western Flycatcher."More ID Info

- Cool Facts
- The Cordilleran and Pacific-slope flycatchers are very similar, and can be distinguished only by very slight differences in body and feather measurements and by voice. Even voice is difficult, with only the position notes of the males differing, and those differences being best detected by viewing a spectrogram.
