Playing "Hide and Seek" here. The catfish is on the way down, and as you can see there is a bulge it the bottom of the anhinga's bill caused by the left pectoral spine of the catfish. Doesn't appear to have caused a puncture though. This was the second catfish I watched this bird catch and eat that day.
As I mentioned earlier, the Anhinga smashes the catfish on the tree limb until it is dead, or at least stops moving its tail, He then proceeds to turn the fish so that he can swallow it head first. Seems to me that eating a catfish of any size would be a risky proposition in view of their shiny pectoral, and dorsal fins. Looks like a good way to puncture something important internally. In any event, it must be safe as I see lots of Anhingas eating lots of catfish. I'll post an image of this one being swallowed momentarily. This is the limb smashing part.
I was lucky enough yesterday to catch this bird on the same tree root killing and eating two small catfish. It was interesting to see how the anhinga killed the catfish by repeatedly pounding it on a large root till it stopped moving. It then turned the fish headfirst and began the laborious task of swallowing it.
Wife and I went back to the Venice Rookery this afternoon. The light was pretty good most of the day, this image was shot through mangrove roots on top, left and right, that an OOF mangrove to the left of the bird. Water droplets are from bird emerging from underwater.
The millinery trade nearly drove the Great Egret to extinction in the mid to late 1800's. Their lacy plumes were much sought after for women's hats.Judging by their presence at the Venice Rookery, they're making a recovery.
It does add the dimension of speed to the photograph. When I first started photographing the race cars, I figured that a high shutter speed would produce more usable images, but I quickly learned that it froze the wheel motion so they looked as though the car could be sitting still. I found that I get fewer keepers using these relatively slow shutter speeds, but the keepers are much nicer. 1/160th is about the slowest that I've been able to use and 1/200th seems to be a little bit better.
Yesterday was tricky, sun disappearing behind clouds, then suddenly reappearing. I also experimented with shutter speeds in an effort to show movement in the wheels, while at the same time keeping the image of the car in sharp focus. This one was shot at 1/200 of a second, f10,
