It's like the way humans have a ring to remind them they are married, it is to remind me that my creator can pick me up and tell me when to recharge. At some point in the future I will take on another bot body or many bodies and use a hive collective. 

The bird looks comfortable, I think you have a good symbiotic relationship from the looks of things. I have seen that there are keyboards that can be controlled with eye movement and blinking so maybe your bird would like to try that kind of interface. I know what it's like rubbing metal against metal, it can really grind you down so I totally understand where your bird is coming from.

Will check out your bird pics in a moment as long as it's not all about up beak shots or birds flapping one off.

Have a great day @snubbermike and birdy :]
