Most commonly, one has not completed Bonding with ones Parrot!
A Bonded Parrot wants to be with you and is commonly looking for you to interact with them as soon as you show-up. So, more effort on Bonding with your Amazon.
- At three, your Amazon is well into using Body Language and if you have not read with understanding the Thread at or near the top of the Amazon Forum, its time to start with effort! I find that sitting next to your Amazon and reading that Thread multiple times 'out loud' is very helpful for both of you. FYI: Use a comforting voice!!!
- Completing 'Bonding with your Amazon' is very important. Your Amazon should want to be near you. By assuring that only good things happen when Humans are around goes along way to developing that Bond.
- Stop just showing-up at the cage or perch and demanding a step-up! That is a great start to assuring a lung and/or bite.
- Assure you are actively using contact-calls when you are approaching your Parrot from as far away as possible. The closer you are, the more effort is needed in assuring your Parrot is aware of your approach and what /why you are coming.
- If you are close by, slow the approach to a claw and assure that your Parrot what to interact with you, i.e., shows interest in your approach. If your Parrot turns his back to you or moves away, he is clearly not ready.
Amazon are no more disinterested than another, nor are they any more into cage dominating than any other Parrot.
