Gila Woodpecker
Gila Woodpecker
Melanerpes uropygialis
At a Glance
A brash, noisy woodpecker of desert regions. Common and conspicuous in stands of saguaro, or giant cactus, it also lives in the trees along desert rivers, and is quick to move into towns and suburbs. This species and the Gilded Flicker are the two main architects of desert apartment houses: the holes they excavate in giant cactus are later used as nesting sites by many other birds, from flycatchers and martins to owls and kestrels.

Habitat
Desert washes, saguaros, river groves, cottonwoods, towns. Generally in dry country, but requires suitable sites for nesting cavities: cottonwood groves along rivers, large mesquites or willows, palms, giant cactus such as saguaro or cardon. Readily adapts to suburbs of southwestern cities. Also dry tropical forest in Mexico.

Behavior
Eggs
3-4, up to 6. White. Incubation is by both sexes, about 14 days.
Young
Both parents feed young. Age at which young leave nest not well known, probably about 4 weeks; accompany parents for some time thereafter. 2-3 broods per year.
Feeding Behavior
Forages on tree trunks and cacti, in outer branches of trees or shrubs, or on ground. When seeking insects on tree trunks, generally probes or gleans at surface, rarely excavating for food. Often drinks sugar-water from hummingbird feeders.
Diet
Omnivorous. Diet includes wide variety of insects, also cactus fruit, other wild and cultivated fruit, berries of shrubs and mistletoe, nectar from flowers, seeds, small lizards, earthworms, eggs and sometimes young of smaller birds.
Nesting
Displays, used largely in aggression, include exaggerated bowing and head-swinging, accompanied by loud calls. Nest site is a cavity excavated in giant cactus or in tree (cottonwood, willow, or large mesquite), sometimes in palm trunk. Cavity usually 8-30' above ground. Both sexes take part in excavating. Cavity in giant cactus cannot be used for several months, as inner pulp of cactus must dry to solid casing around cavity; holes may be excavated one year, used the next.
Conservation
Conservation Status
Declined seriously in California portion of range during 20th century. Still abundant in southern Arizona.
