I see these birds often down at Sand Creek. I've been photographing them and telling people about the white herons I keep seeing. The first photo is what I've been assuming is a heron. Then yesterday, I saw several birds that looked like the ones I've seen, but are just a just a little different. I'd been told there were a lot of Egrets out there that day. Is that what these are? Or am I just confused?
