Nuttall’s Woodpecker
Nuttall's Woodpecker
Dryobates nuttallii
At a Glance
A California specialty, Nuttall's Woodpecker extends only a short distance into Baja and rarely strays to Oregon. Within its limited range, it is often common wherever oak trees grow. It may go unseen at times because of its habit of foraging among densely foliaged oaks, but it frequently announces itself with sharp calls. Despite its close association with oaks, it tends to dig its nesting holes in other kinds of trees, and it eats only small numbers of acorns.

Behavior
Eggs
3-4, up to 6. White. Incubation is by both sexes (with male incubating at night and part of day), about 14 days.
Young
Both parents feed young. Young leave nest about 4 weeks after hatching, may remain with parents for several weeks thereafter.
Feeding Behavior
Forages mainly in dense trees such as oaks and ceanothus, also in cottonwood, willow, sycamore, and others; sometimes in yuccas, mesquites (at eastern margin of range). The sexes sometimes forage differently in trees, with males focussing on trunk and major limbs, females working on minor branches and twigs. Occasionally catches insects in flight.
Diet
Mostly insects. Feeds on a wide variety of insects, especially beetles, also caterpillars, ants, true bugs. Also eats some nuts, seeds, fruits, berries. Despite close association with oaks, eats only small numbers of acorns.
Nesting
Members of pair may remain more or less together all year. Displays include raising head feathers, swinging head from side to side, and a fluttering display flight. Nest site is cavity in live or dead tree, usually cottonwood, willow, or sycamore near oak woods, sometimes in utility pole, fence post, or oak or other tree. Cavity usually 3-35' above ground, sometimes up to 60' or higher. Male does most of excavating; new nest cavity every year.
