Ospreys frequently go completely under water when diving after fish.
This leaves the bird with a lot of very heavy water as excess weight on its body.
They solve the weight problem by shedding the water.
Like a dog, they start at the beak and do a full body, very vigorous, twisting shake back to the tail.
I caught this osprey at the point of the shake reaching his midsection; his beak almost back to its normal position.

Brassy doesn’t care who she harasses, like this osprey.
All bald eagles will chase an osprey that is carrying a fish.
The eagle crowds or actually bumps the osprey until it drops its fish.
Usually the eagle snatches the falling fish before it hits the water.
Yes, the bald eagle is a thief.
Osprey is up top and Brassy is closing fast from the lower right.

this male osprey came in from my left, plowed into the fish, caught the fish with his right talon
he then snapped his wings full up and back and lifted himself and the fish from the river
an unusual viewing angle for me

this is the typical aerodynamic way that an osprey carries its catch
they turn the fish around into this position, mid flight
