Marsh Bird Survey
Starting in early June, observers visit Harpers Meadow , Sweat Meadow, Leonard Marsh and the Dead Cambridge River to record activity of target marsh birds. Target species are Virginia rail, sora rail, American bittern, common snipe and pied billed grebe. Virginia rail and common snipe are the most frequently encountered species. Each marsh is visited 3 times between June and July every year.
Land Bird Survey
Observers walk a route and stop at designated points to record all birds seen or heard. The survey data will be used to identify birds occurring on the Refuge during the breeding season, to associate species with habitats, to monitor changes in bird populations, and to help make appropriate management decisions. The most abundant land bird species thus far are red-eyed vireo, ovenbird, hermit thrush, winter wren, magnolia warbler, northern parula, white-throated sparrow, yellow rumped warbler, common yellowthroat and Swainson's thrush.
During the spring and fall migration, surveys are conducted on waterfowl and shorebirds migrating through the area.
