Whoa! That is some great video.
One of the coolest things I've witnessed in person was last trip up to the Rainy River/Lake Nippising in Ontario a couple years ago. Bald Eagle came down and plucked a good sized smallmouth bass (guessing 2-3 lbs)out of the water near a shoreline not more than 50 yds. from the boat. At first I wondered if he was even going to be able to fly with it it was so large, but he certainly managed and flew off to have a hell of a lunch somewhere!
