Red-collared lorikeets — a type of parrot — show up every year in Australia acting like they've been hitting the fermented fruit juice a little too hard. Locals report symptoms like "falling over" and "difficulty flying" and "running into things" and "act[ing] friendlier than normal," which will be familiar to anyone who’s ever gone to college. (Don’t ask about “difficulty flying.” That was a bad night.)

Ok, but less funny — the "drunken" lorikeets also have respiratory problems and goop coming out of their noses and eyes. In the past decade, more and more birds have shown up with the problem. And many with the symptoms will end up dead. Are they drinking to forget that they have some mysterious allergy?
