Hard to do much with the photo and the sense of scale. Helmeted Guineafowl are from Africa and are common domestic birds, and there is actually one subspecies that has a white face, but I'm not convinced this is your bird either. There are a number of pheasants, guans, quails, and other birds that have a fairly similar color pattern, but I think it would take a better photo to make an identification. Sorry, this is a great question and I wish I could find the answer.
