Lucy's Warbler, Vermivora luciae, is the smallest New World warbler found in North America, measuring a mere 4.25 inches in length. It is rather nondescript compared to other wood-warblers. Its head and upperparts are pale gray, while underparts are whitish. It has a white eyering and a small, pointed bill. Both sexes have a rufous rump, a diagnostic field mark. Adult males also have a small rusty crown patch. Juveniles are paler, with a tawny rump and buffy wingbars.
