From the author: Most Red-cockaded Woodpecker (Picoides borealis) populations are in pine forests that have been harvested at least once and are relatively young compared to old-growth stands. We quantified foraging behavior, year-round home range, and woodpecker productivity for groups within and proximal to an old-growth longleaf pine (Pinus palustris) stand from late 1992 to late 1993 in southwestern Georgia. Average year-round home range size for seven woodpecker groups in and adjacent to the old-growth stand based on minimum 95% convex polygons was 47.1 ha. Year-round home range was negatively correlated with the percentage of the home-range located within old-growth forest. In the old-growth stand the size class distribution of trees selected by woodpeckers for foraging was different than the distribution of trees available in size classes [greater than]30 cm dbh. As in other studies, males and females differed in foraging height and parts of the trees used. Clutch size and fledging rates of the seven study groups were also higher than reported in other studies. Red-cockaded Woodpeckers preferentially forage on large (and presumably old) trees. The small year-round home range, high density, large group size, and high productivity indicate that this old-growth longleaf forest is high quality habitat. We suggest that forest management intended to provide an adequate number of replacement cavity trees and quality foraging habitat for the Red-cockaded Woodpecker should have old trees across the landscape.
