I have been photographing several Yellow-crowned Night-Herons on just about every trip to the Sequoyah National Wildlife Refuge in Oklahoma for the past couple of months. They have been in an area that is called Miner's Cove. This area is full of Crayfish.
I can count on seeing this one Yellow-crowned Night-Heron being in the same spot next to the road. I have arrived at this spot just at daylight and wait for the Heron to show up. I may have to sit in my pickup for an hour waiting for enough light so that I can get some photos of this bird catching Crayfish. The wait is not bad at all because the Heron is catching and eating Crayfish.
It is amazing how much they will catch and eat. I have never taken the time to count, but should try one of these days.
