Californian condors have been bred in captivity for 27 years, ever since their population dropped to a mere 22 birds. Today, more than 220 of these New World vultures live in the wild. Saving a species seems laudable, but critics say captive breeding practices alter the bird’s wild essence. While they can survive alone in nature, zoo-bred condors often suffer from behavioral issues, including aggression towards humans. Considering that the baby birds were raised by condor-shaped puppets, it’s hardly surprising they’re suffering a bit of angst in their teenage years.
