Associated Species: Other species that may use habitat in a similar way and/or respond similarly to threats, management, and conservation activities include American Kestrel, Great Horned Owl, Northern Flicker, Western Kingbird, Eastern Kingbird, Yellow Warbler, and Bullock's Oriole.

Distribution: Lewis's Woodpeckers breed from central British Columbia and western Alberta south to northern Mexico, and as far east as eastern Wyoming. In Colorado, Lewis's Woodpeckers reside in the valleys, plains and foothills from 1100 to 2400 m (3,500-8,000 ft) in elevation. In Physiographic Area 87, Lewis's Woodpeckers are year-round residents in western valleys, although some withdraw to lower latitudes during the winter.

Habitat Requirements: Lewis's Woodpeckers breed in riparian forests, agricultural areas and urban areas with scattered, mature cottonwoods, adjacent to areas of low vegetation, such as ungrazed or lightly grazed grasslands, mowed hayfields, or fallow fields. In southeastern Colorado, mean dbh of nest trees was 112.6 cm (44.3 in), significantly greater than that of unused trees (Vierling 1997). These woodpeckers avoid dense riparian forests, and those which contain Red-headed Woodpeckers. They excavate their nesting and roosting cavities in the soft wood of dead or decaying trees, or rely on natural cavities or cavities excavated by other woodpeckers because they have relatively weak bills and skulls and cannot excavate cavities in sound wood.

Ecology: Lewis's Woodpeckers initiate nesting by late April, and most young leave the nest by the end of July. The diet during the warmer months is largely flying insects, caught on the wing. During colder months, the diet shifts to nuts, grains, and berries.

Management Issues and Conservation Recommendations: Lewis's Woodpeckers depend upon large trees and snags and are sensitive to disturbance at the nest. Reduce or eliminate activities that degrade the structure and quality of the overstory or understory of riparian systems. Do not permit timber cutting within 100 feet of the riparian area. Locate recreational facilities such as roads, trails and campgrounds up, out of riparian areas.

Competition with European Starlings for limited nest cavities may limit breeding success of this species in some areas. Research ways to reduce competition from these unprotected, introduced birds.

Status and Reasons for Concern: This species has a high conservation need locally and throughout its range. This species is on the national Watch List, indicating a high conservation need throughout its range. This is a USFS Sensitive Species in Region 2. Long-term declines in some areas are extreme. The Lewis's Woodpecker is not adequately monitored by the BBS, and data are too sparse for meaningful analysis of trends. This species was present on an average of 7.00% (SE = 2.76) of routes run in Physiographic Area 87 in Colorado, 1988-1997, at an average abundance of 0.12 (SE = 0.04) individuals per route. The mean number of routes run each year was 11.4 (SE = 1.55). This species is monitored by MCB with tracking transects.

Biological Objective: Increase the species' distribution and abundance, with progress toward this objective measured by results of the BBS and MCB monitoring programs.
