I captured this image at Circle B Bar Reserve in Polk County, Florida. The adult female had just returned to feed the chicks. She regurgitates food into their open beacks, the scene is rather frantic with them wanting more and more. There is a third chick inside the nest cavity that can just slightly be seen by a path of white in the shadow. These two are definitely the dominant chicks. Comments and critique welcomed and appreciated. Thank you for viewing.

P.S. I also have worked up the image as a vertical but I like this better.
