Ibises are about the size of chickens and also make homely clucking, chirping and tweeting noises. Here they are crossing the entrance to the drive.
There were a bunch of black birds (but not, I think blackbirds) with them too - evidently after the same goodies. In Europe or up north there would be flocks of starlings. This is Florida of course and everything's bigger.
Elsewhere, on Golden Beach, it was early morning and someone had found breakfast.
