Snowy-throated Kingbird Tyrannus niveigularis Scientific name definitions

Snowy-throated Kingbird is a striking, conspicuous flycatcher of the Pacific coast of northwestern South America. Found from southern coastal Colombia south to northwestern Peru, the species inhabits open areas and woodland edge below 500 m in elevation; this species also is partially migratory, which is somewhat surprising for a species with a small geographic range that is centered on the Equator. Snowy-throated Kingbird is gray above with a stout black bill, blackish wings edged in white,  a black mask, and a white throat that blends into a bright yellow belly. The Snowy-throated Kingbird is smaller, paler below, and grayer-backed than the similar Tropical Kingbird (Tyrannus melancholicus), with which it overlaps geographically. Snowy-throated Kingbird also can be recognized by its sharp kip calls, which sometimes are strung together in an excited stutter.
