- ORDER: Passeriformes
- FAMILY: Tyrannidae
The petite olive-and-yellow Cordilleran Flycatcher of the Rocky Mountains nests in high-elevation coniferous forests, usually along canyons or ravines with flowing water, where there are gaps in the canopy. Here, the species forages mostly by flying out to capture passing insects. Nearly identical to the Pacific-slope Flycatcher of California, the two forms were formerly considered to be the same species, known as the “Western Flycatcher.”More ID Info
Find This Bird
Cordilleran Flycatchers return to nesting grounds in the Rockies by late spring. Track down this bird by locating a trail that follows a steep-sided ravine with a creek or small river wide enough to create gaps in a coniferous canopy, and then listen for its short three-note song.

- Cool Facts
- Cordillera is the Spanish word for mountain range. This species’ common name reflects the fact that it occurs mainly in the cordillera made up by the Rocky Mountains and Mexico’s Sierra Madre.
- Migrant Cordilleran Flycatchers are little known on their wintering grounds in Mexico, where they are very difficult to distinguish from Pacific-slope Flycatchers, Pine Flycatchers, and especially from the resident Mexican subspecies of Cordilleran Flycatcher (occidentalis).
- Cordilleran and Pacific-slope Flycatchers look virtually identical—even more alike than other Empidonax species. Away from their breeding habitats, the call notes of males are the only way to distinguish the two species; they typically sound single-syllabled in Pacific-slope but two-syllabled in Cordilleran. The calls of females of the two species are indistinguishable.
