This is a shot I almost missed. I had photographed the male hunting, and just finished with a young Owl. I could not find anything else.
I did finally find (OK, Ellen found) the female standing guard. She is usually near her chick, watching for danger.
A Barred Owl is large enough that once fully grown they have few enemies. However, there are a few here. Bald Eagles, Red-tailed Hawks, and Great Horned Owls will attack them.
Of course down below are the usual Alligators who hunt where they do.
