The Gila woodpecker (Melanerpes uropygialis) is a medium-sized woodpecker of the desert regions of the southwestern United States and western Mexico. In the U.S., they range through southeastern California, southern Nevada, Arizona, and New Mexico.
The back and wings of this bird are spotted and barred with a black and white zebra-like pattern. The neck, throat, belly and head are greyish-tan in color. The male has a small red cap on the top of the head. Females and juveniles are similar, but both lack the red cap of the adult male. White wing patches are prominent in flight. The dark tail has white bars on the central tail feathers. They range from 8–10 in (20–25 cm) in length.
This woodpecker's voice is a rolling churr sound. It also makes a yip yip yip sound and a kee-u, kee-u, kee-u sound. Its drum is long and steady.
Distribution & habitat
This woodpecker's habitat consists of low desert scrub typical of the Sonoran Desert.
Behavior and ecology
They build nests in holes made in saguaro cacti or mesquite trees. Cavities excavated by these woodpeckers in saguaro cacti (known as a "boot") are later used by a variety of other species, including the elf owl. There, they typically lay 3–4 white eggs, although as many as 6 or 7 have been noted. 2–3 broods are laid a year. Both sexes incubate and feed eggs.
As a woodpecker, its diet is composed greatly of insects, which it gains from drilling into bark. Gila woodpeckers are omnivorous, and do take fruits, nectar, seeds, as well as lizards, eggs, worms, and even young chicks of small birds. They are even known to hang on human placed hummingbird feeders and sip up the nectar.
The IUCN rates the species as least concern. It is an endangered species in California, where populations have suffered notably. Arizona populations remain strong. It was once found in Nevada, but has been extirpated from its range there. The effects of climate change could severely reduce available habitat.

Cavities in saguaro cactuses in the Southwest are common. Both gilded flickers and Gila woodpeckers make these cavities for nesting, but they often choose different locations on the cactus.

Although they do not use them immediately, waiting first for the sap to harden, Gila Woodpeckers excavate cavities in cacti and trees as nesting sites.
