Einstein the African grey parrot at Zoo Knoxville is 30 years old today. (They call it his "hatch day.") In honor of the occasion, the zoo released a video of Einstein showing off his impressions, sound effects, and singing. He has quite a repertoire!
Einstein was purchased for the zoo from a breeder in California at the age of 5. The talented parrot is an ambassador for the zoo, has appeared on TV, and even gave a TED talk in 2006. -via Laughing Squid
