What makes a Great Blue Heron happy? How about catching a really big fish. This Heron caught some sort of big, flat fish and to be honest, I never thought he'd get it down. It took him about 15 minutes (probably waiting for it to stop flopping around) to down his meal, so the video is an edited version. In the last few seconds, you can see his distended neck as the fish slowly goes to his stomach.
Herons frequently fish in the lake, but I've never seen one in a tree. This one perched in the birch tree for about half an hour. He's got an impressive wingspan.
In the picture below you can see that there's another Heron on the sandbar. They are very territorial birds and don't hesitate to drive intruders off so I wonder if that's his mate fishing.
I really like watching Herons. Not only are they beautiful birds with a dignified demeanor, but they are also much better fishermen than most humans I know.
