The Black-throated Gray Warbler (Dendroica nigrescens) is a small songbird of the New World warbler family. These birds have a black crown, a white face, a thin pointed bill, white wing bars, grey upperparts with black streaks on their back and white underparts with black streaks on the flanks. Adult males have a black throat and cheeks; females have a white throat and dark grey cheeks. Their breeding habitat is open coniferous and mixed forests in western North America, especially with oak, juniper or pinyon pine. The nest is an open cup usually placed on a horizontal tree branch. The female lays 3 to 5 eggs; both parents feed the young.
These birds migrate to Mexico and the south-western United States.
They forage actively in low foliage, sometimes hovering or catching insects in flight. They mainly eat insects, especially caterpillars.
The song of the male bird is a buzzed zee-zee-zee-bzz-zee. The call is a sharp tup.
