I take the covers off his cage and he immediately starts looking and singing at himself in the mirror:

It means he's a happy birdie! That's Coco, isn't it?

Yes! That's Coco. I forgot to mention it

Beaker and Jaid sing that song too!!

My flock sings differently, so I wonder where Coco learned that song. A study on wild Amazon parrots established that each flock has their own "language" where they tend to call in a particular style, and I get the impression that it's the same with cockatiels. But Coco has learned a new language!

Awww cute.

Hmmmm... Could it have been that when I first got him I listened to cockatiels singing? I think it's the standard thing to sing with cockatiels. Tough Pip sings differently. He sounds beautiful when he sings.

Also, this reminds me; Pip is male. I don t know if I had mentioned it before but I'm convinced he's male.

He certainly sings like a male!
