Snowy-throated Kingbird Tyrannus niveigularis

Gray, white, and yellow flycatcher with a bandit mask. It breeds during the rainy season in deciduous forest and scrub; some birds then disperse into more humid regions for the rest of the year. Probably not present year-round at the northern limits of its range. Compared with the more common and widespread Tropical Kingbird, it has a white throat and breast with no olive tones, and a more conspicuous black mask. A yellow crown patch may be exposed when the bird is excited.
