Endangered Shorebirds: Protecting rare shorebirds is a collaborative effort from various biologists, private organizations, state agencies, beach managers, and volunteers. The Waquoit Bay Reserve has participated in rare shorebird monitoring and conservation efforts since 1990. WBNERR monitors South Cape Beach and Washburn Island, which are part of the Reserve, and also private nesting areas at New Seabury Beach and the Menauhant Yacht Club Beach. Population monitoring serves as an integral aspect of recovery efforts for an array of shorebirds. It allows wildlife managers to identify limiting factors, assess effects of management actions and regulatory protection, and track progress toward recovery. Actively protecting piping plovers (Threatened) and least terns (special concern) at WBNERR also protects the beach, dune and marsh habitats for many species of wildlife including a wide variety of shorebirds and rare tern species that use the barrier beach and coastal salt marsh system to feed, nest or stopover during spring/fall migrations. Arctic, Common, Roseate and Least Terns rest on our beaches and forage in the waters off South Cape and Washburn Island. Nearby Buzzards Bay, hosts the largest Federally Endangered roseate tern colony in North America.
