A video from Apollo the parrot has been viewed as the smartest parrot we've ever seen on YouTube. Apollo lives with his human parents, Dalton and Tori, in Florida and they are teaching him a "preschool-level homeschooling education" inspired by Dr. Irene Pepperberg's work with an African grey parrot named Alex. If you're interested in training a parrot to speak with you, keep training sessions short and have a better outcome if you wait until the bird is naturally chatty and clearly having fun. The training is also recommended for consistency and high-pitched voices.
