These really are called Cattle Egrets. I thought I would show these smaller of the egrets with both gorgeous horses and the more familiar cattle. I snapped these pictures from the fences of both a horse farm and a cattle ranch. Both the horse farm and that cattle ranch are in an area Northwest of Ocala, in Marion County, Florida.
I was amused at seeing Cattle Egrets paying attention to the horses. The egrets flew along as the horses ran around their very large pasture. These egrets eat grains and insects so following along with these large animals makes it possible for them to find an easy meal. As far as I could see, the larger animals did not seem to mind. No, the egrets are not parasitical, but they do take advantage of what is a natural situation. Please click on the thumbnail image to see the larger picture. Enjoy!
