"For bird watchers, this Townsend’s warbler was at our feeder recently":
The Audubon Society says about the birds:
The coniferous forest of the Pacific Northwest is the summer home of Townsend's Warbler. There the sharply marked males sing from high in the spruces and hemlocks; their buzzy songs are quite variable, and some are similar to those of the Black-throated Green Warbler, an eastern relative.
Most Townsend's go to Mexico or Central America for the winter, but small numbers remain along the coast north to Oregon, Washington, and even Vancouver Island.
