Salt Marsh Birds

Salt marshes are a dominant ecological community within coastal US Fish and Wildlife Service (USFWS) National Wildlife Refuges (NWR) from Maine to Virginia , and especially within Refuges located in Delaware (Bombay Hook and Primehook NWR). Saltwater tidal marshes are listed as “habitats of concern” by the Delaware Department of Natural Resources and Environmental Control (Delaware Wildlife Action Plan Draft Document, 2005). Salt marsh breeding bird populations (rails, bitterns, sparrows) in eastern North America are high conservation priorities because of the limited information about their breeding ecology, reproductive success, and the limited distribution of salt marsh habitat to the thin interface between marine and terrestrial ecosystems. Presently, the status and trends of these species are unknown but may be declining.

We are iniating research and monitoring to address issues associated with salt marsh bird reproductive biology, habitat selection, mercury contamination, detection probabilties, and effects of marsh management on breeding populations.
