Roughly matching the distribution of the
poderosa pine, the Lewis’s Woodpecker occurs during
breeding in western North America from eastern British Columbia
south to New Mexico, west to western California and east to
Colorado. In the early 20th Century it expanded onto the plains
of southeastern Colorado, apparently due to the presence of
mature cottonwoods and cornfields. In winter it withdraws
from the northern part of its range and typically occurs in
oak woodlands and orchards. It occurs sporadically within
its breeding range, disappearing for years at a time and then
returning in some numbers. In summer it eats mostly insects
in in winter switches to acorns and other nuts, often storing
them in bark crevices. It engages in aggressive encounters
with other species of woodpeckers over these caches. It favors
open forests, ranging altitudinally from low-elevation riparian
areas with cottonwoods to burns and ponderosa pine forests
at higher elevations.
There are no estimates of its total population
size, but Breeding Bird Surveys and Christmas Bird Counds
indicates it may have declined by about 60% since the 1960s.
The bird depends on standing large dead trees for nesting
and old cottonwoods or power poles with desiccation cracks
for winter storage sites. These are increasingly rare features
of the landscape. The bird would be helped through not logging
old-growth ponderosa pine forest or burned coniferous forest,
retaining these in open, parklike stands, maintaining snags,
and not densely replanting trees after cuts.
