If you've spent much time on a sailboat, you've probably spent some time around ospreys. Also known as a seahawk, or a fish eagle, they are powerful and beautiful birds of prey. And if you haven't seen them in all their glory, I thought I would help you out (go for fullscreen if you have a fast internet connection):
Of course, on the other end of the seabird spectrum, you have the lowly seagull. They are loud, they
scavenge, they scrap. And sometimes they do something funny and improbable, like stealing a running Go Pro camera, shooting a birds-eye view of San Francisco Bay, and then depositing it, still running, on the deck of a yacht club (Saint Francis?).
