Hoatzins. Hoatzins are badass. As hatchlings they're born with claws on their wings so they can climb up trees and onto branches and the like until they're capable of flight - but they lose the claws once they reach adulthood. Is it creepy? Kind of. Do hoatzins care? Not in the least. They're just here being seemingly inexplicably weird and there's nothing you can do about it. They could climb all over your roof if they wanted to. With creepy little birdfingers. It's okay though, because they eat almost nothing but leaves, flowers and fruit, so you're safe from the fingerbirds unless you're a tree.
Have a video of a baby hoatzin being adorable.
