Vagrant records exist for Arizona, New Mexico and Texas. It is yellow on its throat and underparts with a tawny wash on its chest. The head is gray with a black framed yellow crown and white around the eyes. The undertail coverlets are white. They are 5.8 6.3 in 14.5 16  cm long and have pleasant, upslurred song. Fantailed Warblers live in and at the edge of evergreen forest evergreen and semideciduous forest, especially near ravine s. They eat ant s, especially army ants , and are seen hopping around on either the forest floor or close to it. They are found alone or in pairs. The Fantailed Warbler is sometimes placed in the genus Basileuterus , since its nest, eggs, voice, and juvenile plumage are similar. However, no Basileuterus warbler has a tail or a tawny breast like the Fantailed s, so it is generally kept in the monotypic genus Euthlypis .
