Lewis's Woodpecker Life History

Habitat

Habitat Open Woodlands

Lewis's Woodpeckers frequently breed in open ponderosa pine forests and burned forests with a high density of standing dead trees (snags). They also breed in woodlands near streams, oak woodlands, orchards, and pinyon-juniper woodlands. During the nonbreeding season, they move about in nomadic fashion stopping off in cottonwoods near streams, orchards, and oak woodlands with plentiful resources.

Food

Food Insects

Lewis's Woodpeckers eat insects, nuts, and fruits. Unlike other woodpeckers they tend to eat flying insects that they take in midair or pick from a branch or tree trunk, rather than probing for wood-boring insects. They store acorns, other nuts, and grains in the crevices of cottonwood trees in the fall and winter.

Nesting

Nest Placement

Nest Cavity

Lewis's Woodpeckers nest mainly in holes and crevices created by other woodpeckers or created naturally in dead and decaying trees (snags). They nest in cottonwood, ponderosa pine, paper birch, white pine, and other trees that are starting to decay. On occasion they nest in live trees.

Nest Description

The nest is a cavity or hole most often in a dead or decaying tree. They use existing holes or crevices, rarely excavating their own, but they often enlarge or remodel existing cavities. They line the bottom of the cavity with wood chips.

Behavior

Behavior Aerial Forager

Lewis's Woodpeckers hitch up trees in typical woodpecker fashion, but they also perch perpendicularly on branches and on top of wires and posts, something other woodpeckers don't often do. They fly out from these perches to catch insects in midair on long forays in flycatcher fashion. In fall and winter, their diet shifts to include more acorns and other nuts, which they store in the furrows and crevices of trees. Lewis's Woodpeckers are protective of their winter stores of acorns and nuts. If an intruder enters into their winter stores or breeding territory they might chatter, throw their bill up, lift their wings above their body to expose the pink belly feathers, fluff up their neck feathers, or circle the nest tree with wings held up in a prolonged glide. They are particularly aggressive toward Acorn and Red-headed Woodpeckers that try to steal their caches. Courting males also call, lift their wings up, and circle around a nest tree to attract a female. Following breeding, some form small groups and wander nomadically in search of nuts and fruits. Others stay put year-round or move to lower elevations.

Conservation

Conservation Declining

Lewis's Woodpeckers are uncommon and their populations declined by 72% between 1970 and 2014, according to Partners in Flight. Due to their declining population, they rate a 15 out of 20 on the Continental Concern Score, placing them on the Yellow Watch List. The current estimated global breeding population according to Partners in Flight is 69,000 individuals. Lewis's Woodpeckers are threatened by changing forest conditions as a result of fire suppression, grazing, and logging as well as climate change. Fire suppression, logging, and grazing often result in higher densities of single age pines and fewer standing dead or decaying trees available for nesting.

Backyard Tips

Provide habitat in your yard for Lewis's and other woodpeckers by leaving a dead tree standing if it isn't threatening your home. Learn more about standing dead trees and how to create bird friendly habitat in your yard at Habitat Network.
