That is a very neat style of taxidermy. Reminds me of the work from one of my favorite after the hunt wildlife artists from Louisiana, George Louis ViaVant. He painted water colors of fish and game hung like that on nail or peg. What I like about his paintings was he hunted and painted his works during the heyday of Parker in early 20th Century. Heck he might of even used a Parker to harvest his game. You don't see that style very often.

BTW do you have other birds mounted like that or what made you decide to it that way. Again I think it is a neat piece.
