Wow. That's a good sized bird, but what does she feed them? Aren't they fish eaters?
They have a big pond in the back yard (complete with requisite Florida alligator) and the birds go there to feed. All their backyard birds are big - herons, ibis, various creatures I've never seen before. I love sitting safely behind the screened in lanai big-bird watching. Some of them are also really loud. One morning, something was screaming like a banshee back there at about 5am.
