Distribution maps were prepared from data collected in a survey of birds in the Park during the nesting season of 1999. Bird survey points were established at 250-m intervals. At each point, a 10-minute count of birds heard or seen was conducted on one morning during late May through June. This survey is part of a Bird Inventory project for National Park Service parks administered by National Capital Parks-East. The project, conducted by biologists from the USGS Patuxent Wildlife Research Center, is jointly funded by the Inventory and Monitoring Program of the National Park Service and by the U.S. Geological Survey.
