Thanks all.
We're taking all advice and trying to make prudent decisions. I have a few further questions:
1) This site seems a little difficult to navigate. I see no way to sort posts by date or user, am I missing something?
2) Anyone have experience with the www.birdtricks.com videos?
3) When my bird shakes, meaning his body is basically still, his head is still but his body feathers (mostly breast) are shaking, is that a sign of fear, cold or something else. Our home is usually around 67, I'm believe I read that to be acceptable.
4) His pupils dialate in and out quickly at times. I can't find much on that behavior. Any thoughts?
Thanks you all again, you've been very helpful.
