Momo gets in the shower and sings every day. He doesn't necessarily wash, but he gets in there and sings about it the whole time. Today he was rather subdued honestly. Usually he sings up a much bigger storm, he was more animated towards the end though.
I don't know if it's because Caiques originate from the jungles of the Amazon, but every time there's water running or falling, he is super excited about it, especially if it rains or the shower is going. Momo seems to celebrate the "rains" every time they come.
