Owen Channel is a body of water that lies between the southeastern end of Manitoulin Island (Lake Huron, Ontario) and Fitzwilliam Island. These islands are low-lying to gently sloping in this location.
In the fall and early winter, significant numbers of moulting Red-necked Grebes are found in Owen Channel. In the fall of 1994, 220 were seen here. This represents about 1% of the eastern population of the species.
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.
