3. Collared Pika

With a name like that it’s understandable that people may wonder just what these things are. These small critters (about as big as a tennis ball) live in Alaska and surrounding areas and survive by eating a diet that consists mostly of flowers. They spend all summer gathering a stash of flowers that typically weighs about 30 times as much as they do! They use the stash to survive the long Alaskan winter. What really makes them creepy is their habit of collecting dead birds and putting them in cold storage as well. When the mood strikes during their long winter period of inactivity, it will grab a dead bird, break open its skull with its sharp teeth and eat the brains. And you thought it was just a cute, cuddly little mouse kind of thing.
