Ocean is always more willing to have my (millet-bearing) hands near him if I've done some out-of-cage work with Firefly first. I don't know if it boosts his confidence level to see another bird being handled without fear, or if seeing another bird get treats makes him want treats more... only that it doesn't work with Kalu. Kalu out of her cage fills Ocean with tiny, cheepy rage. (Then Kalu says "You're so cute!" to him, which makes me laugh. I'm so mean.)
