"Ooh, yeah, scratch right there..."
Osprey are amazing birds. They mate for life, spending the spring, summer and early fall breeding, hatching and raising their young. Typically, here in the northwest part of the United States, they depart in the early part of October for their winter nesting grounds. The male and female leave at separate times for different locations, usually in Central America. Sometime in March the following year, they arrive at the same nest they shared the previous year to start the cycle again. The male almost always arrives several days before the female. They possess an advanced navigation and communication system that humans, even with the latest technological advances in GPS and satellite communication, will likely never approach.
The photo here shows a part of the mating process - it was taken at a lake in Western Oregon near the town of Cottage Grove.
