Her pieces — which include rings, ear rings and necklaces — aren't made from the actual skulls themselves, mind you. They're actually resin copies made from a silicone mould which is shrunken down from the skull's natural, attached-to-the-bird's-neck size.
Her skulls come from Sparrows, Magpies, Crows, and Parakeets — there's even a raccoon femur key chain. Prices range from $US7 to $US20, though her Etsy page is currently having a Dollar Off sale. [Etsy]
