Abstract

We investigated the use of pine plantations by Worm-eating Warblers within the coastal plain of North Carolina during the breeding seasons of 1997 and 1998. A total of 60 plantations, representing 10 age categories within the growing cycle, were surveyed for warblers using fixed-radius point counts. Worm-eating Warblers appear to colonize plantations around the time of canopy closure. Singing males were detected within 95.2% of plantations that were 10 years old or older. Mean density within these plantations for both years combined was 0.56 birds/10 ha. With the exception of understory density, habitats used by Worm-eating Warblers within the study site appear to be distinctly different from those reported from other populations throughout the species range. The history of landuse within the region suggests that the use of pine plantations by Worm-eating Warblers is a recent event. Habitat attributes that result from open-canopy pine management appear to mimic those of the historic tall pocosin habitat within the region where this species still breeds in high densities.
