The Pale-billed WoodpeckerCampephilus guatemalensis, is a very large woodpecker that is a resident breeding bird from northern Mexico to western Panama.
It resembles the Lineated Woodpecker, but is larger and more robust. The adult is mainly black above with a pale bill, bushy crest, and white lines down the shoulders which almost meet in a V on its back. The throat is black and the rest of the under parts are white, heavily barred with black. The male has a red head and crest; the female is similar, but the crest and throat are black. The female can be distinguished from the Lineated Woodpecker by the absence of a white facial stripe.
