Herring Gull Egg Monitoring – Granite Island, Black Bay

On May 29th, Shane Desolla of Environment Canada, assisted by Albert Holder of Hurkett, Ontario and Jim Bailey of the North Shore of Lake Superior Remedial Action Plan office at Lakehead University in Thunder Bay landed on Granite Island on Lake Superior’s Black Bay to continue work on a program which monitors contaminants in herring gull eggs.  This program was begun in the seventies. The number of nests on the island were counted, eggs were measured for size and a limited number of eggs were taken to analyze for contaminants. Shane Desolla has completed similar work at sites around the Great Lakes in both Canada and USA and Albert Holder has been assisting for about 8 years, especially with use of his boat for transport to Granite Island. This was the first trip to Granite Island for Jim Bailey.

Where is Granite Island? In fact, where is Black Bay on Lake Superior? The north end of Black Bay is roughly 70 km. northwest of the city of Thunder Bay, Ontario. It is one of the largest bays or arms of the lake (roughly 60 km. in length), very shallow, flush with wetlands on the perimeter and even with a unique water colour differentiating it from the main body of the lake. Check out this map showing Black Bay. See a closer view showing Granite Island in the northern basin of Black Bay

The following pictures from the May 29th, 2013 Granite Island trip offer an excellent “snapshot” of this unique, longstanding program which provides a wealth of information about the interaction between human activity and the Great Lakes.
