Reoccupation of Abandoned Clusters of Cavity Trees (Colonies) by Red-cockaded WoodPeCkers
We documented red-cockaded woodpecker (Picoides borealis) occupation of cavity tree clusters on North Carolina study areas from 1980-88. Most occupied cavity tree clusters (93%) were used in consecutive years, but 6.8% were abandoned each year. Abandoned sites were captured or reoccupied at an annual rate of 8.7%, implying there is a 60% chance that an abandoned site will be reoccupied in a 10-year period. However, recently abandoned clusters were reoccupied at a much higher rate than long-abandoned clusters. Cluster occupation was dynamic with some being occupied, abandoned and reoccupied...
