This first photo is a Brown Cowbird. They are an unfortunate nuisance at my bird feeder. I wish they would stick with the cows. The second one is the female which appears to have a tick on her neck? I don't think a tick would get much out of a bird but that is out of my range of knowledge.
After letting these pictures settle for a little while, I thought I'd try a different orientation on the great egret picture. I think I like it better. The "gator ramp" he is standing on gives some interest, as well as minimizing the dead background.
