Charles Paddock Zoo, Sept 2024. Unsigned. They have Madagascar Partridge in a neighboring aviary but this bird looks more rufous so wasn't sure if it's a female or a different species?
@Coelacanth18 Yes the Tennessee Red mutation looks good to me. The Northern Bobwhite has a heap of subspecies, some of which are much darker or much more reddish than the typical, so I was thinking it would be one of them but they are difficult to find good pictures of online, especially the females.
