If a vampire bird looks at you like this and you’re for some reason dressed up like a bird, flee immediately.

‘Wolf Island, an often brutally dry rock in the [Galapagos] archipelago, is ruled by vampires—hordes and hordes of tiny vampires. These are the so-called vampire finches, enterprising critters in a brutal environment that have figured out how to nip at the tail feathers of other birds until they draw blood, somehow without their victim putting up much of a fight. Even though they don’t sparkle or battle werewolves or whatever, they’re marvels among the many marvels that are the famed Darwin’s finches.’ (Wired)
