Awesome photos. Last week a lady found a limpkin about 30 minutes away from me at Joyce WMA. I might try to see if it's still around to photograph this week. She posted a good photo on ebird, not as good as yours, but good enough to be 100% confident on the ID. They're super rare for some reason in Louisiana, they just wander in by accident. You'd think they'd love our climate but apparently even a couple of freeze days a year and they don't!
