Diego's really my talker, and Petunia is mimicking him! The key for me was taking a sound that they make naturally, and repeating it back to them with words. And just the luck of a bird that will adapt to it. I never expected it, it just happened! Diego has Whatcha Doin, Peekaboo (Chickie and Jojo helped with that!), Pretty pretty birdie, and I think I've heard "Diego" and "Step Up"!
