Townsend’s Warbler Description
Upperparts are olive-green, with a black throat and upper breast. Yellow with black stripes on the lower breast and sides, white on the belly. Yellowface with a black crown and cheek patch and a yellow crescent beneath the eye. Two white bars are visible on the wings. The tail is white on the margins, with a black core and tip.
These birds have a length of 4.75 – 5 in (12-13 cm) and a weight of 9 g (0.3 oz). Their wings could range from 7.5-8 in (19-20 cm).
Primarily insects. While nesting, it feeds primarily on insects, including caterpillars, true bugs, beetles, and leafhoppers; it also consumes a few spiders, seeds, and plant galls. Additionally, on tropical wintering grounds, feeds on berries and nectar.
Townsend’s Warbler spends the summer in the coniferous forest of the Pacific Northwest. There, males with prominent markings sing from high in the spruces and hemlocks; their buzzy songs are fairly varied, and some sound similar to those of the eastern relative, the Black-throated Green Warbler.
Forages primarily in the upper reaches of trees. Actively searches for insects among twigs, frequently hovering briefly to retrieve objects from the foliage. Occasionally flies out to collect flying insects. Except during the breeding season, frequently feeds in groups with other warblers and small birds.
