It seemed like 5 minutes, but according to the time stamps on my images it was 30 minutes. I hadn't gotten very far on my early morning walk along West Bank Park (5:40 start time) when a Great Blue Heron flew in. Fine - mark one GBHE. It was pretty close but in the shade, what the heck I'll take a few pictures. It was stalking upstream, a mallard disturbed it and it flew upstream and on the bank side. I'll see how close I can get. There is a solid wall of willow spikes between the river and me - but I see it (her?) And as soon as I do she comes up with a fish - not just a snack, but this is a dinner for 6. It was dead right away as she dropped it quite a few times and picked it up again. I know she was cautious and knew I was there. But, she was not going to leave a meal that size. Or maybe she just had to keep trying to get it oriented correctly. Once she did - it slipped down in a blink of the eye. I got a couple pictures in focus through the willows and you can see the bulge in her neck after the big swallow. It looked like a bottom feeding fish (carp) - you can see the fish lips in one of the pictures I have. I have posted a couple of the pictures, 3 with the fish and 2 "post swallow".
I thought it might be a "she" - there was a lot of feather loss/bare skin on the legs, chest, arm pit areas. From brooding?
The wood ducks (that I've been seeing all week) were ho-hum after watching this.
