Status and habitat use of breeding northern harriers at Cape Cod National Seashore
Bowen RV. 2006. Status and habitat use of breeding northern harriers at Cape Cod National Seashore. National Park Service
This report presents the results of a two year field study of the breeding ecology of Northern Harriers (Circus cyaneus) in the Cape Cod National Seashore (CCNS). Harriers are of interest because their populations have declined markedly throughout the Northeastern United States, and consequently they have been listed as a Threatened species under the Massachusetts Endangered Species Act. This study was designed to gather information on the Northern Harrier's current status and management needs in CCNS, and the major research objectives were: to survey as much of the suitable harrier habitat in the park as possible and determine the number and spatial distribution of harrier nesting territories; to quantify the reproductive success of nesting harriers; and to determine what habitat types harriers utilize for nesting and foraging in CCNS.
