Since it was found in Louisiana, and it is made of clay with Haitian and African overtones, I think it could be a Voo Doo ring. There are some Voo Doo dolls with clay heads and/or clay bodies. The front of the head/face is very well sculptured, but the ring portion and ring attachment is crudely made. This could mean the head was used as a Voo Doo head, then later the clay ring was attached. It doesn't appear to me the same person made the ring portion as sculptured the head. Most interesting find

WELCOME to the forum!
I've had some other thoughts about this piece. Looking at the front/head, the lines are almost too exact and done with precision to be handmade. Look at the lines in the feathers, hair/forehead, eyebrows,etc. All of these are well defined and straight. I'm thinking now the head could have been machine made, and the clay ring added.
I also wanted to ask if there were any holes in it? I didn't see any, but thought if there were holes, it could be a whistle/ocarina.
