Black-throated Gray Warbler
The black-throated gray warbler or black-throated grey warbler (Setophaga nigrescens) is a passerine bird of the New World warbler family Parulidae.
It breeds in western North America from British Columbia to New Mexico, and winters in Mexico and the southwestern United States. The habitats it prefers are coniferous and mixed forests and scrubland, especially those with pinyon pines, junipers, sagebrush, and oaks.
It has spread into parts of Wyoming and Montana only recently, as Juniperus osteosperma has expanded its range due to a warming climate. It primarily eats insects that it plucks from trees and shrubs. It tends to forage in the lower to middle levels of the forest, moving with slow, deliberate hops while looking around for insects.
