Killough Bay is located in County Down in Northern Ireland, and encompasses intertidal areas and adjoining areas of notable habitat including mudflats, sand-dominated beaches, gravel and cobble units and rocky shore. The boundary of the Ramsar Site includes Killough Harbour and Coney Island Bay. The principal interest is the wintering population of light-bellied Brent goose Branta bernicla hrota, which feeds on the rich mats of the green alga Enteromorpha spp. which are especially present in Killough Harbour. The birds find refuge here during late winter and spring, once the main wintering flock from Strangford Lough disperses due to lack of food.
