Occurrence Notes
Likely an uncommon spring and fall migrant throughout the region, but because only calling males can be separated from Pacific-slope Flycatcher, most migrants cannot be identified to species. Spring and fall migrant “Western Flycatchers” are uncommon throughout the region, with spring migrants seen from 7 May to 8 Jun and fall migrants from 2 Aug to 25 Sept. Data source: Gatlin, BP. 2011.

Notes
Flycatcher (Empidonax occidentalis) * Cordilleran Flycatcher, once lumped with Pacific-slope Flycatcher as a single species called “Western Flycatcher,” is a rare and local summer resident of ponderosa pine forests, particularly near springs on the Kaibab Plateau (Wise-Gervais 2005d). There are few confirmed instances of breeding. Cordilleran Flycatcher is likely an uncommon spring and fall migrant throughout the region, but because only calling males can be separated from Pacific-slope Flycatcher, most migrants cannot be identified to species. Spring and fall migrant “Western Flycatchers” are uncommon throughout the region, with spring migrants seen from 7 May to 8 Jun and fall migrants from 2 Aug to 25 Sept. Data source: Gatlin, BP. 2011.
