Townsend's Warbler

Dendroica townsendi

A bird of the Pacific Northwest, the Townsend's Warbler nests in coniferous forests from Alaska to Oregon. It winters in two distinct areas: in a narrow strip along the Pacific Coast, and in Mexico and Central America.

Cool Facts

The Sibley Field Guide to Birds of Western North America by David Allen Sibley
  • The Townsend's Warbler hybridizes with the Hermit Warbler where their ranges overlap in Oregon and Washington. The hybrid zones are rather narrow and appear to be slowly moving, with the more aggressive Townsend's Warbler displacing the Hermit Warbler.
  • On the wintering ground in Mexico, the Townsend's Warbler feeds extensively on the sugary excretions of scale insects. Although the warbler usually forages in the tops of trees, it will use patches of the honeydew-producing insects at whatever height it finds them. It will defend territories around trees infested with the insects against other Townsend's Warblers as well as other bird species.
  • The male Townsend's Warbler begins to sing before it leaves its wintering grounds.
  • Sometimes a female Townsend's Warbler will partially construct a nest in one tree, then move all the materials to another tree and finish the nest there.
