This is a Great Egret that I photographed eating Crayfish on the side of the tour road located at the Sequoyah National Wildlife Refuge in Oklahoma.
We have had lots of rain in this area this spring. The Great Blue Herons and the Great Egrets are back in the flooded areas of the Refuge. I haven't been able to photograph them from my pickup because of this.
The great egret feeds in shallow water or drier habitats, feeding mainly on fish, frogs, small mammals, and occasionally small reptiles and insects, spearing them with its long, sharp bill most of the time by standing still and allowing the prey to come within its striking distance of its bill, which it uses as a spear. It often waits motionless for prey, or slowly stalks its victim. (Source: Wikipedia)
How I Got The Shot - Great Egret
I had my camera resting on a bean bag draped over the open window of my pickup. I was using a Canon EOS 7D Mark II with a Canon EF 500 mm f/4L IS USM lens. I was shooting in aperture priority mode (AV) with a shutter speed of 1/2500 of a second at f7.1 and the ISO at 640. White Balance was set on auto. I was using single point, continuous auto focus with evaluative metering.
