King vultures can neglect their chicks, so hand-feeding is necessary to ensure the baby survives, the Bronx Zoo said in a statement Tuesday. But to make sure it doesn't imprint on humans, staff train the bird's instincts onto a hand puppet that's crafted to look like a real vulture.

The Bronx Zoo in New York is using a specially designed hand puppet to feed its new king vulture chick, which is intended to prevent the baby bird from becoming too dependent on humans.
