Cool!
I've seen a white-splotched one once, a reddish one, and a bluish one (looked like a pigeon).
The crazy thing is that all 3 of those, across a span of about 5 years, were seen on one 80-acre property in Hardeman County. They were all hens.
The "blue" one I was actually able to draw a bow on, but couldn't get a clear shot inside of my comfortable range. Really cool to see in the wild, though.
