The rufous-capped warbler (Basileuterus rufifrons) is a New World warbler native from Mexico south to much of Central America, rarely occurring as far north as southeastern Arizona and south Texas. Rufous-capped warblers generally reach a length of about 12.7 cm (5.0 in). They are plain-olive to olive-gray, with white underbellies, bright yellow chests and throats, and a distinctive facial pattern consisting of a rufous cap, a white eyebrow-line (or superciliary), a dark eye-line fading into a rufous cheek, and a white malar marking. The bill is rather stout for a warbler, the wings are round and stubby, and the tail is long, often raised at a high angle and flicked.
