Gray-crowned Woodpecker (Colaptes auricularis) is a medium sized woodpecker that is endemic to western Mexico. This woodpecker has a gray crown and bronzy green upperparts. The sides of the face and underparts are cream, barred on the underparts with olive. The male has a broad red "moustache" streak. This species is similar to the more widespread Golden-olive Woodpecker (Piculus rubiginosus), and formerly was classified as a subspecies of Golden-olive. Gray-crowned Woodpecker occupies moist tropical highland forests and montane oak-pine forests at mid-high elevations. The IUCN has not listed this species as one of concern, although very little is actually known about the life history of this species. Partners in Flight assessed Gray-crowned Woodpecker to be a species of tri-national concern as its required habitat is highly vulnerable to human disturbance and human impacts are diminishing the forests and woodlands it requires.
