Gouldian Finches are beautifully colorful birds native to the Australian coast. As adults, they're stunningly beautiful—but they don't start out that way. Gouldian finch babies are, in a word, horrifying.

The hatchlings are born with reflective blue beads on their beaks that look like tiny, creepy pearls. The bright nodules help parents see and distinguish their babies in the dark; when the babies open their tiny, nightmarish mouths, the parents see the flashing blue and know it's time to feed them. The video above shows 3-day-old chicks waiting to be fed.

About a month after being born, the babies grow a nice feather coat, and they look a lot less like Mongolian Death Worms.
