I am thinking based on a few things that this may be a fraud. It is extrememly suspicious.
1. I think we are led to believe that this is the head.
2. The feet are rather suspicious being straight up.
3. The angle and curve of the wing? doesn't match items 1 and 2.
Ok.... here's my synopsis of things. If item 1 is supposed to be where the head is it makes item 3, the curve of the wings backwords based on item 2, the feet. The curve should be inverted. from what it is currently.
A possibility is this. Item 1 is not the head and that bird had the worst case of hemroids ever. This would make items 2 and 3 consistent.
I don't claim to be an expert.
