I don't see enough of these birds, they are around, but usually far out in the marshes. The spread wings pose is typical behavior, the shade created by the wings makes it possible for the heron to see through the surface glare. This bird was hunting small crabs. The crouch is also typical, they will stand like this until sure of a catch, then strike.
It takes a sunny day to do justice to the colors, today was cloudy with a sea fog coming in. I set saturation for max, it is easier to desaturate a bit than to add colors that aren't there. I'm never as pleased with the rusults, however.
