Bird Fact Friday – Townsend’s Warbler

From pages 440-442 in The Warbler’s Guide:

Townsend’s Warbler is easily identified by its high-contrast yellow face, which also contains a dark ear patch and yellow undereye arc. These warblers have variably black throats boarded by yellow, and dark streaking. In addition, they have a dark olive-green back and white wing bars. Their dark flight feathers contrast with their yellow bodies. Additionally, Townsend’s Warblers are identified by their white bellies and tails. They also have a distinctive, contrasty facial pattern.

This warbler breeds in conifers; during migration, they can use a range of habitats, but are often found in pines whenever available. Their breeding range overlaps with Hermit Warbler’s, and hybrids between the two are found annually. Townsend’s Warblers are typically found in the western part of the United States.
