General description.

The most distinguishing features of this trim and tiny warbler are his white face stripes and wing bars, as well as the yellow ovals in front of each eye. He is tame, like his cousins, the Black-throated Green and Blue Warblers, letting curiosity seekers within several feet of the nest.

Female appearance.

The adult female's plumage is more subtle, with a white throat and dark gray cheeks.

Breeding habits.

The "Black-throated Gray Warbler" breeds in the tall conifers of the Pacific Northwest, and further south, he favors dry, brushy slopes. He ranges from southwestern British Columbia along the Pacific coast, and east to New Mexico and southern Montana.

Calls or song.

Flat and unmusical, this bird gives a sharp tup, like that of Townsend's Warbler, and a series of buzzy notes. When following the female as she gathers material for the nest, he will sing a drawling chant.

Population and distribution.

"Black-throated Gray Warbler" has spread into parts of Wyoming and Montana only recently, as Juniper bushes have expanded its range due to a warming climate. This warbler winters mostly in Mexico.

Nesting habits.

The nest is usually placed on a horizontal tree branch or in a shrub, a few metres above the ground. It is a cup constructed of grass stalks and other fibres, and lined with feathers and hair. The female lays 3–5 pinkish eggs with brown dots.
