Small short-tailed warbler; bright and boldly patterned. Blue-gray above with green back, two bold white wingbars, and yellow-orange throat and chest. Males have darker face and brighter yellow-orange chest than females. Bill is sharp, black above and yellow below. Very similar to Northern Parula; note lack of white eyearcs and no dark markings on breast. Beware, of rarely-occurring hybrids and that some dull immatures are very similar to Northern Parula. Common and widespread in forests throughout Central and South America; rare in U.S.; found only in mossy forests in southern Texas.
