Townsend's Warbler

Overview

Townsend's Warbler breeds in tall coniferous forests along the Pacific coast and interior mountains of western North America, then migrates to winter from California south through Mexico and Central America. Its bold facial pattern makes both the living bird and its shed feathers relatively easy to identify.

It closely resembles the related Hermit Warbler, and the two occasionally hybridize where their ranges meet, so feathers from the overlap zone can show intermediate features.

Recognizing the Feathers

• Face feathers: bold black cheek patch (auriculars) and crown bordered by bright yellow
• Throat feathers: black in males, yellow with variable dark mottling in females
• Back feathers: olive-black with streaking
• Underpart feathers: yellow breast fading to white or pale yellow belly with dark side streaking
• Wing feathers: dark with two bold white wing bars

The black cheek patch outlined in yellow is the most distinctive single feature separating this species from most other warblers, though it should be compared carefully against Hermit Warbler where ranges overlap.

Plumage

Adult males show a solid black throat and black cheek patch against yellow head feathering; females and immatures have a paler, more yellow throat with only partial dark markings. Plumage is fairly similar year-round, with one complete molt after breeding on the breeding grounds and typically no additional molt before spring migration.

Habitat & Range

Townsend's Warbler breeds in tall, mature coniferous forest from southern Alaska through the Pacific Northwest and into parts of the northern Rockies. It winters along the Pacific coast from California to Mexico and Central America, often in mixed conifer or oak woodlands.

Behavior & Field Notes

This warbler forages actively in the outer branches and tops of conifers, gleaning insects and occasionally engaging in short flycatching sallies. It builds a well-hidden cup nest on a horizontal conifer branch and sings a buzzy, ascending series of notes. Winter flocks sometimes join mixed-species foraging groups with chickadees and kinglets.
