Analysis of information sources in references of the Wikipedia article "Gila woodpecker" in English language version.
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.
