摘要

We quantified habitat use of nesting Lewis' Woodpeckers (Melanerpes lewis) in southeastern Wyoming on an 11, 100-ha study area consisting of scattered ponderosa pine (Pinus ponderosa) stands. A 1295-ha burn in 1974 and a 1590-ha burn in 1986 occurred prior to the study. Our results showed nest sites occurred in burned areas, which had more ground cover and downed logs. Birds were found in sites where visual obstruction of the sky including vegetation and burned branches was higher than non-use areas.
