Abstract
Dendroica virens waynei (Wayne's Warbler) is a unique, disjunct subspecies of Dendroica viren virens (Black-throated Green Warbler) that is restricted to the South Atlantic Coastal Plain from southeastern Virginia to South Carolina. We surveyed a network of 265 fixed-radius plots to examine seasonal occurrence, spatial distribution, and patterns of habitat use by Black-throated Green Warblers. Survey plots were chosen to represent the full gradient of forest types within the region. Plots were surveyed 7 times between early April and mid-June, 2001. Detections of Black-throated Green Warblers began in early April, increased to a peak in late April, and then declined throughout May and early June. Birds were detected during 251 (13.5%) of 1862 point counts conducted. Detections were widespread and included 114 of 266 (52.6%) survey plots. Forest composition had a significant influence on the distribution of breeding sites. The frequency of plots classified as breeding sites was higher than expected for plots containing Pinus taeda (Loblolly Pine), Chamaecyparis thyoides (Atlantic White Cedar), and Taxodium distichum (Bald Cypress). The density of these tree species within survey plots was significantly higher for plots classified as breeding sites compared to plots classified as unoccupied. This response was particularly significant when all three tree species were combined.
