Habitat management for an endangered species may affect nontarget communities. We examined avian community response to pine-grassland restoration for red-cockaded woodpeckers (Picoides borealis) and traditional United States Forest Service pine sawtimber management at Homochitto National Forest, Mississippi from 1994-1996. Thirteen species were more abundant in pine-grassland restoration stands, whereas 5 species were more abundant in traditionally managed pine sawtimber stands. Mature restored pine-grassland stands had greater avian species richness, total bird abundance, and avian conservation value than traditionally managed pine sawtimber stands. We used logistic regression models in an exploratory analysis to predict occurrence of selected species using stand- and landscape-scale habitat characteristics. Probability of red-eyed vireo (Vireo olivaceus) occurrence increased with increasing hardwood canopy cover, and probability of yellow-breasted chat (Icteria virens) occurrence increased with increasing grass ground cover. Species richness, total avian abundance, and occurrence of red-eyed vireos and Bachman's sparrows (Aimophila aestivalis) increased with increasing values of Shannon's Habitat Diversity Index. Pine-grassland restoration for red-cockaded woodpeckers created vegetation composition and structure at the stand and landscape scales that may benefit numerous avian species of regional conservation concern.
