Burd

Cute little bird one moment, predator the next. The branch like things in it's mouth can wrap around a human hand and rip it to shreds. By the time you could get away from it it would likely have gotten to your elbow. And of course the trauma from having that much of your arm ripped off would likely kill you after awhile. While waiting for it's victim to perish burd usually follows them until they've passed. Then it has a meal for a long while.
