Similar Species Eastern Wood-pewee C. virens (L 6-6.5 in) is almost identical; separate using summer range (much of eastern North America, barely overlapping with Western's range) and song (tri-syllabic pee-err-wee). Plumage is paler than Western, with more obvious wing bars, and orange on lower mandible.
Discussion Slimmer and longer-tailed than Olive-sided Flycatcher, with more pronounced wing bars and uniformly olive-brown breast (without central white line bordered by dark "vest"). Compared to Willow and Alder Flycatchers, darker overall, with less striking wing bars and relatively longer wings (extending well beyond rump when perched). Legs are dark and bill is mostly dark, but with dull orange base to lower mandible. Makes aerial sorties after flying insects, from perch at mid-tree level (lower than Olivesided Flycatcher). Sexes are similar.
