Long-beaked mamal

The long-beaked mamal specializes in eating a food which most radfauna have become disinterested in: Mirrorbugs. Instead of trying to shoot the mirrorbug with a gamma ray beam like an idiot, it simply tears it limb from limb with its long beak. This provides a good source of lead to the long-beaked mamal, making its beak big and strong. Due to their lack of fur, they are no longer able to live in the tundra, and are easy prey for similarly sized radfauna. They still have their death beam organ complex but only use it for self defense.
