Oh gosh that was a big read ! haha
I agree with Monica 100%, encourage behaviours you WANT, and the bad behaviours will disappear...
Fargo doesn't scream for attention, instead he now yells 'Mum'... I was getting ready to go out yesterday, and Fargo just say saying- Mum? Muuuum! Mum.. Mum!
I couldn't stop laughing, i went in and talked to him and told him i would be back soon
But he doesn't scream! I never never punished him for screaming.. Instead when he says a good word, i will respond to him, so he knows that 'Oh, if i say mum, she thinks it is funny and will come to me!

'
If a bird is getting in that grumpy kind of mood, have a toy with you, so they will bite the toy and not you! I always play with Fargo and his foot toys, i always have foot toys on my desk.. Fargo has never bitten me!!! If he wants to play rough.. He has toys he can play rough with, because i have given him positive reinforcement that is 'Yep, you can bite that toy all you want!!! You don't need to bother biting me!'
People seem to think that because a bird is small, we can manhandle them in making them behave....
A bird? Just place it in a pillowcase for a time out... Easy...
I challenge you to come to my 900kg horse, and try and 'manhandle' him when he is acting up...
If he wanted to... He could kill you... Thats it... One kick, one rear, one trample, you could be gone...
So do you think i try and use negative reinforcement with my massive horse? HELL NO!!!
I can tell you that if he is misbehaving whilst riding, and i get upset with him or make him do something, he gets even worse, and i can NOT control a 900kg horse, with my puny 60kg body!
So... If my horse is misbehaving.... I start from the beginning..
Oh, you want to go a bit fast around the jumps? Nope... Let's just walk and learn our leg aids for 5 minutes and do some trotting poles...
and then 10 minutes later, after we have realised what i want, he does the jumps perfectly!!!
I know it is horse related, but you can cross animal behaviour!!
When i got my horse, i was told 'Do not ride him on roads, he is petrified of cars, and he will bolt'
Yep.. This horse would try and run away if he saw a car... Did i smack him, tell him he is naughty and punish him?
Definitely not, i patted him, i soothed him...... That horse doesn't even look twice at a car anymore, and rides along the roads perfectly... Because i made EVERYTHING positive, so he had no reason to be upset/angry!!!
Treat your bird like he is a 900kg horse who could do alot of damage to you, not just a handful which you can make it do anything you want because you say so!
Start from the beginning, and work your way up in baby steps!
Everyone has their own opinion, that is perfectly fine!
But in my opinion, working with MANY animals, being negative is not the way to go
Fargo is incredibly well trained, no bite, no scream, trick trained, sits in his cage all day without a problem, and i achieved this by always teaching him through a positive way...
I never chucked him in a pillowcase, he would probably want to rip my hand off if i did that
I have never done anything negative towards Fargo that would make him want to be upset and bite me!
and i taught him from day 1 how to be independent, how to play with toys, so he doesn't scream whenever he is alone!
Ok,phew, all done

hahahah
