My lutino cockatiel likes to 'talk' to his water. He makes sounds as if he's 'laughing' at it, chattering to it even as he's drinking it! Especially when it's fresh or fresh millet has ended up in it. I'll have to provide a video sometime, I don't have one of him doing it yet. Usually when he does it I go to grab just the iphone right quick and he'll stop. Anybody else's birds do this? It's so amusing every time.
