Haha, yes, I've been trying to describe that sound to my friends, and can't quite seem to work it out . And they're not really that quiet, that was just a quiet moment, normally they're quite loud. Well, Piper is, anyway (hence the name). Every morning, at about 8:30, Mickey will suddenly go crazy, making this really high-pitched squeak, and trying to break out of the cage. I soon realised he does it because he wants to be taken outside! It's become a ritual, he squarks, I take them outside, they play and make noise, then he'll pipe up and make the same noise in the afternoon, letting me know to bring them back in.

Now THAT is adorable. Mine make noise in the morning but annoying squawking I think only to let me know they are up. Wasabi gets mad after I feed him and give him water and chews me out for being in his cage. The Red Rumps just I think try to call to all the outside birds.
