Olive warbler peucedramidae
The Olive Warblers (Peucedramus taeniatus) are native to North and Central America.
They occur from southwest USA from Yavapai County, Arizona and the southwestern tip of New Mexico, as far east as the mountains of far west Texas. In Mexico, their range stretches from central to southern Mexico, with isolated populations in Tamaulipas and Coahuila in Northeastern Mexico, and Sonora and Chihuahua in Northwestern Mexico.
Further south, they are found in southwest Guatemala and from northern El Salvador and central Honduras to northern Nicaragua.
The back and most of the wings are grey, with some olive-green markings on the wing and two white wing bars. The lower chest down to the undertail coverts (feathers) is whitish.
The males can be identified by the orange-brown head, throat and chest , and the black facial mask extending through the eyes.
The head of females and juveniles is orange instead. The crown is greenish and there is a yellow-orange wash to the throat and chest. They have dark cheek patches.
