Site description (2001 baseline):
Numerous shorebirds and waterfowl fly along the south shore of Manitoulin Island on their way northwards in the spring, but most of these birds do not stop at Quarry Bay or the adjacent bays and shoreline. Common Loons, scoters, and Oldsquaw are some of the species seen in spring migration.
The moulting locations that Red-necked Grebes use in the vicinity of Manitoulin Island share several characteristics. They are generally between 100 to 2,000 m away from the shoreline, the water depth varies from 3 to 55 m, they are partially sheltered (that is in the lee of islands or in large bays), and have varied lake bottom topography containing shelves or holes.
