The local osprey have begun returning from thier winter homes in South America. Right now they are re-establishing nest sites or selecting new ones. The males tend to arrive first as they need to be well started on getting the nest back up to shape before the females will accept them. Most osprey pair shack up with established mates on existing nests. This male already has met up with his significant other and she is sitting in the nest below him out of the frame. They will start mating in a few days.
