I assume that this tiny beauty is a male, not that I've seen the female to compare with. And I *do* mean tiny - look at the moss to give you an idea of the size.
Painted Button-quail are supposed to be moderately common. If so, they are nevertheless elusive: this was the first one I've ever seen, though years ago I did once spend 20 minutes stalking a "Painted Button-quail" which, once I got close enough, magically morphed itself into a rusty coke can!
