Sounds like a Bob White but has no white feathers

HELP - there is a bird in my yard who has been here two days - he sounds just like a Bob White quail but his body is solid brown and his head is solid black - no white on it at all. He calls just like a Bob White - I cannot figure out what it is and there are no others responding to his/her call. I feel sorry for it and don't know how it ended up here. I have been feeding it but am worried that perhaps it belongs to someone and has escaped. Any help??
