His vocalizations are fun. He will occasionally assert himself and have a little jag of squawks. The rest of the time he is inventing his own little whistle song or will mimic the dogs. So far he can say, "Edgar is a good boy", "Hello", call the dog "Ollie, come here" (along with the whistle we do), whistle the theme to the Addams Family (along with the snaps, squeaky door, mimic us when we laugh and the "you-who" whistle. The quality of his voice isn't as good as a Grey or Amazon but you can still understand what he says. He can also time what he says or whistles to the appropriate moment/occasion.
Edgar's play is also fun to watch. He especially loves untying/re-tying knots, dismantling screws and chewing on chopsticks. Chicken leg bones are his favorite. He chews them up and eats the marrow. Loves tofu, chicken, turkey, etc.
