Site description The eastern arm of the Bay of Fundy can be divided into two areas: the lower Minas Basin (IBA # NS020) and the upper Cobequid Bay. Cobequid Bay is a long (40 km) point-shaped bay that widens from 1.5 km at its eastern end, to 15 km at its juncture with Minas Basin. The coast and shoreline of the bay consists of beaches and mudflats with substrates ranging from fine silts to coarse sands, depending on the currents and distances to various sediment sources. At low tide, vast areas of mud and sand flats, and salt marshes are exposed - the result of the highest tides in the world (up to 16 m), which are found in the Bay of Fundy. The rich red-brown mud harbors millions of the amphipod, the Fundy mud shrimp (Corophium volutator), a vital food source for many shorebirds, particularly Semipalmated Sandpipers. The Cobequid Bay IBA includes the following areas: Economy, Highland Village, Little Dyke, Black Rock, Stirling Brook, Noel Shore, Noel Bay and Moose Cove.
