One Leg Up Reddish Egret

This Reddish Egret was just standing on one leg for about an hour. I was shooting other birds flying in and out, hunting for their meals and interacting with each other. This one was just standing on one leg watching what was going on. I usually do not see them that motionless for that long. At least being that still made for a good subject to photograph.
