Western wood pewee

The western wood pewee (Contopus sordidulus) is a small tyrant flycatcher. Adults are gray-olive on the upperparts with light underparts, washed with olive on the breast. They have two wing bars and a dark bill with yellow at the base of the lower mandible. This bird is very similar in appearance to the eastern wood pewee; the two birds were formerly considered to be one species. The call of C. sordidulus is a loud buzzy peeer; the song consists of three rapid descending tsees ending with a descending peeer.
