Ospreys go in, I mean often way deep under water when fishing.
The dive picks up a lot of water on the body of the osprey.
Water weighs 8.35 pounds per gallon.
Flight calls for a bird without an excess load to haul into the air.
Ospreys do a shake to shed the excess water. The shake is just like what a wet dog does.
The shake starts at the beak and twists through to the tail.
Here you can see the osprey is ahead of the spray and the shake has gotten almost to the tail feathers.
