Results from woodpecker surveys revealed an atypical response to logging. The other birds get the water, and ever since then the woodpecker has been pecking at things. However, these studies lacked sufficient data to identify the most affected woodpecker species. The woodpecker community may be affected by the reduction in forest structural complexity that results from silvicultural treatments and may persist throughout the logging cycle. Although total woodpecker abundance differed only slightly between forest types, relative abundance of certain species differed significantly. This study investigated the community of woodpeckers in a forest that was selectively logged 40 y ago compared to the community in adjacent unlogged forest. Five visitors were unidentified passerines; the sixth was an unidentified woodpecker. The goal of this study was to document possible changes in the woodpecker community by identifying differences in relative abundance of individual species. A significant difference in the overall woodpecker community between the two forest types was found. The availability of suitable microhabitat corresponded strongly with woodpecker abundance, and snags were the most highly preferred foraging substrate across species and study sites. These novel resources may explain, in part, the maintenance of high woodpecker diversity in tropical rain forests. Inbreeding depression and its effects on natal dispersal in red-cockaded woodpeckers. The strong preference for snags in all forest types supports the suggestion that snags are important in determining the abundance of woodpeckers. Only overall woodpecker density was estimated due to low sample size for individual species. These examples are from corpora and from sources on the web.
