Description ADULT Has gray head and neck grading to gray-olive back. Wings are dark, but note bold pale wing bars. Has white eyering, most striking behind the eye. Underparts are grayish, palest on throat and belly (the latter faintly washed yellow). Postbreeding molt occurs on breeding grounds, hence fall plumage is fresher looking than adults of other similar empids (which molt after migration). Winter plumage is washed yellow-olive overall. JUVENILE Similar to fall adult, but with buffy wing bars and orange base to lower mandible.
