Arizona's Heavenly Gila Woodpecker
According to the Arizona-Sonora Desert Museum factsheet, Gila Woodpeckers are permanent Sonoran Desert dwellers and are found in all of its habitats. This woodpecker can be found in southeast California, southwest Nevada, southern Arizona, southwest New Mexico and south into central Mexico.
Woodpeckers nest in cavities that they excavate with their long beak. In the Sonoran Desert they often make these cavities in saguaro cactus. The inside of a cactus provides a safe, cool place for the woodpeckers to raise their young. The excavated cavity is called a "boot".
