Abstract: Fire is a major disturbance factor that contributes to the regeneration of aspen forests in the Rocky Mountain region. I investigated the potential impacts of burning on landbird community structure in pure aspen forests in the western foothills of the Wind River Range, Wyoming. Bird species composition, richness and relative abundance were compared between six independant pairs of sites, each pair consisting of a recently burned aspen site and a control site. Bird species composition differed consistently among burned-control pairs, but other uncontrolled local factors were likely involved. Bird species richness did not differ significantly between burned and unburned aspen sites. Of 45 bird species, only warbling vireos (Vireo gilvus) and western wood-pewees (Contopus soridulus) were detected significantly less often in the burned sites, while pine siskins (Carduelis pinus) were detected significantly more often in the burned sites. Overall, variability among paired burned-control aspen sites made it difficult to determine the general effects of burning on the landbird community structure. Habitat factors relating to bird species richness were also explored.
