Thank you Karen, I'll look up Spark or something related.
The little guy is so quiet... I got used to all my flock that screech and sing like crazy out in the aviary. He just seems so tiny, I can't get over the fact of how trusting he is. I was able to get my hand within a foot of him outside, anything could have snatched him up!
He's started singing and exploring the cage! He's more inquisitive too.
Found out he likes my singing, because he started responding to me when I was singing and playing guitar (classical) yesterday, and now he calls to me whenever I come into the room and if I talk to him. He has discovered his millet, too. He is hand shy, but can't say I blame him with his past week.
Yes, he's already got me wrapped around his wing feather...
