Attractive, perky, long-tailed warbler widespread in foothills and highlands, locally in lowlands. Favors brushy and weedy areas adjacent to woodland and scrub. Usually in pairs, low in brush, where hops with long tail cocked. Note white eyebrow, rusty cap, and yellow bib. Birds in southeast Mexico and Belize are extensively yellow below. Populations from Guatemala south are shorter tailed, have solidly chestnut cheeks, extensive yellow below, prefer more humid habitats, and sound quite different to northern populations. This form is often considered a separate species: Chestnut-capped Warbler.
