Shaking Off The Water...
A Caspian Tern shaking itself dry after diving for a fish.
To get this shot I would watch for one that just dove into the water, then track it after it took off.
If they had a fish they would either eat it or get a firm grip before shaking off the water. If they didn't have a fish they would shake themselves dry more quickly after emerging from the water.
