Arizona Woodpecker
Arizona Woodpecker
Dryobates arizonae
At a Glance
A brown-backed woodpecker of oak woodland, living in mountains near the Mexican border, mainly in southeastern Arizona. Foraging quietly at mid-levels in the oaks, it is often easy to overlook. Much of its behavior is like that of the Hairy Woodpecker, but it is quieter, often forages lower in the trees, and does not dig as deeply into dead wood for insects.

Behavior
Eggs
3-4. White. Incubation is by both sexes, about 14 days.
Young
Both parents feed nestlings. Age at which young leave nest is not well known; young may follow parents for several weeks after fledging.
Feeding Behavior
Forages by climbing oaks, pines, other trees, tapping and probing, flaking off bits of bark, searching for insects. Also climbs acrobatically among branches, sometimes hanging upside down, and probes at flowers of agaves and other plants. Male (slightly larger and longer-billed than female) spends more time foraging on trunk, female does more on branches and twigs.
Diet
Mostly insects. Feeds on a variety of insects, especially larvae of wood-boring beetles; also some berries and small fruits, a few acorns.
Nesting
Birds may pair up and begin working on nest cavity by mid-winter. Members of pair may drum and tap near potential nest site, and make short gliding display flights nearby. Nest site is cavity in dead stub of large tree, usually 9-50' above ground, sometimes lower in agave stalk. In Arizona, nest cavity is often in walnut (easier to excavate than oak). Excavation is by male or by both sexes.
Climate Vulnerability
Conservation Status
