About a month ago, I went with a friend (obviously, since I don't hang out at boat ramps hitting up strangers for open seats, since that would be creepy and stuff) on the C out of Chinook Landing. On the Washington side, there a couple families of osprey. Dang birds seem to really have the fishing drill down, except their stomach is bigger than their wings -- several times, we saw them scope their target, make a wicked dive beneath the surface, and grab the fish which was obviously much too heavy for them to carry... but they'd make a noble effort before they'd drop it and move on to the next target.
I found it amusing. You see some crazy stuff on the Columbia (rivaled only by the ocean, where anything can happen).
