Driving through Kamloops BC (Interior British Columbia... Above Washington State for you Americans ;D ) I saw these cranes. They had a general sounding crane call, but they were colourless solid gray, and were quite big. Looked like geese when standing still. Anyone know what they are? --Not sandhill cranes (no red on their head) and not common cranes (just, different looking, by quite a bit) and obviously not whooping cranes. Well, I'm out of cranes for the local area... Anyone know?
