It's been a while since I've read up on this stuff. I suppose for doves there would be no skin to give to a kohen.
Another interesting tidbit is that non-Jews are permitted to offer up any kosher animal as a sacrifice (as Noach did after the Mabbul)--unlike Jews, who may offer only certain specified animals.
