They are Taxidermy.

The larger fox on the right, is the fox that my skull came from :)

The taxidermist, Ingrid Houwers http://www.taxidermyni.com/, was at Ballywalter Game fair, so having only spoken on facebook, i had to go and say thanks for my wonderful skull, and to look at some of her beautiful work.
This isnt the best photo, the shine from the tiles ruins it a bit :(

She had lots of different birds on display aswell, along with a stone martin, a mouse and a squirrel, but the foxes where of course my favourites so i unfortuanly only took photos of them. (My fox >:3 cause i have his skull XDDD)

Please have a look at her site :D http://www.taxidermyni.com/
