Yellow-throated Warbler

The Yellow-throated Warbler is a wood-warbler of pine and bald cypress woodland and sycamore-lined waterways across the southeastern United States, with populations wintering in the Gulf Coast states, Mexico, and the Caribbean. It shows a striking combination of gray upperparts, a bright yellow throat and breast, and bold black-and-white facial markings, and is notable for its longer, slightly decurved bill.

Upperpart feathers are plain gray, while the throat and upper breast are a vivid yellow, bordered by black facial markings including a black stripe through the eye and a black crescent below it, set off by white patches on the face and neck. The flanks are white with bold black streaking. Wings show two white wingbars. The bill is noticeably longer and slightly decurved compared to most warblers, an adaptation for probing bark crevices.

Sexes are similar, though females may show slightly less crisp black facial markings than males. Immatures are duller, with reduced yellow on the throat and less defined facial pattern, brightening with maturity. A single complete molt occurs after the breeding season.

This species breeds in mature pine woodland, bald cypress swamps, and sycamore groves along waterways across the southeastern United States, with some populations extending along the Atlantic coast. It winters in the Gulf Coast states, Mexico, Central America, and the Caribbean.

Yellow-throated Warblers forage by creeping along branches and probing bark crevices and clusters of pine needles or Spanish moss with their longer bill, a technique distinct from typical foliage-gleaning warblers. The male's song is a clear, descending series of whistled notes. Nests are often built in clumps of Spanish moss or high in pine trees. It is a relatively short-distance migrant compared to many wood-warblers.
