I know, I know, we get these threads all the time: "My conure bites, screeches, seems bored..." But he was such an angel before.

So here's his environment, most hasn't changed in 8+ months:
Fresh and pellet food that he eats and enjoys, fresh water that he drinks.
Wake at 8am, full spectrum lighting from 8am to 3pm, covered at 8pm.
Average room temp 83 degrees (its 100-ish outside, its the best possible within my budget and the capabilities of the unit, and it is fairly constant) but it was cooler in spring, with the windows open and nice fresh air.
Cage cleaned every 3 days or so.
New toys once a month, rotated every week or so. Including foot toys he likes alot for inside and out of cage.
I got him playstands, but he prefers to velcro to me.
Bath every few days, but he usually only gets "into it" twice a week.
Hours and hours of cuddle and outside cage playtime.

His Lordship the Tyrranical Conure, Rigel. Lately, I can't leave him in his cage for two moments to use my computer, clean my kitchen, eat, or even to use the bathroom without him going with screeching as if I have left him alone for three days with no food and HOW DARE I BE AWAY! So that now I have to use my laptop in the other room, because if I let him out while I use it he will perch on it and become very possessive of it.

Also when I let him out, he jumps directly for my neck sometimes, but usually bites my hand. He's never drawn blood until now. Then he becomes the angel and cuddles like nothing happened.

Thing is, I can't figure out what has changed to make him this way. Maybe it is just because he's a year old now, maybe it is because he can fly now. I can't change the first, and I really don't want to change the other. I thought it would be so great that I could spend more time with him since I'm out of school this summer, and I almost feel like me being here more often is what is pissing him off and making him think I HAVE to be here ALL the time.

*sigh* The clicker training kit arrives soon, right? It will help him feel more enriched and improve his mood, right?
