Small, yellow-olive flycatcher. Brighter yellow than most other Empidonax flycatchers. Look for bold teardrop-shaped eyering that comes to a point behind the eye, and fluffy, peaked crown. Breeds in coniferous forests, often near water; migrants and wintering birds can be found in other wooded or scrubby habitats, but typically stay at relatively high elevations. Essentially identical to Pacific-slope Flycatcher with very subtle vocal differences; identification is usually presumed based on range.
