The sanctuary consists of 164 acres of largely maritime pine forest with several miles of trails. Passerines prefer the oak grove of the old Banding Area to the extreme east end of the Campground Trail and the south boundary of the swamp along the Dune Edge Trail. Swainson’s Warbler is regularly found at the Banding Area and Black-whiskered Vireo may be found there occasionally. In addition, a Painted Redstart was seen here in spring 2011, which accounted for the second state record.
