Last week I spotted a bald eagle swimming. The bird appeared to be doing the butterfly stroke lifting it wings out the water and then plunging them back in with a definite reaching forward to propel itself.
It took me a while to realize what I was actually seeing. The bird passed around a bedrock point and out of view before I could take a picture.
As I continued along the shore I flushed the eagle. The bird managed to lift off the ground with a large fish and despite the troubled take off managed to get into a tree perch where I would not be able to steal his catch.
