Wow! Like just wow!! How dare you ask me this...... my head will be spinning more than usual now for the rest of the day lol.
I personally think all beings (birds, people, any and all other animals) are all much happier and more mentally stable being around someone they can personally identify with.
I do not think I would like to be kept somewhere I did not choose to be (no matter now fun and nice it is) with only the company of something else chosen for me that spoke a completely different language to me and had full control of when they would interact with me..... I think after some time it would be a very sad, disturbing and isolating feeling.
I honestly find this a very interesting thing to think about and I am often finding myself completely engrossed with thoughts on this solitary life situation/ issue we humans keep many "pets' in. I am not really a very social person and I much prefer time on my own or with my chosen animal companions to anything else in the world, but, even I, from time to time need and want some human company to re ground me, remind me of the important things in life or to recharge my soul. I think there is a good reason most animals at zoos are kept in pairs or groups, jails even have limited time allowances for solitary punishments, nature never shows you healthy animals living in isolation full time.
As much as I would like to say I am enough company for Burt, I personally think I would be completely lying to say he could not have a better connection with his own kind. I do think it is beneficial for birds to have other birds in their life to communicate with but I also know of many many birds who lived what seems to have been a very satisfactory life with human companionship alone.
This is a topic that I am sure could have valid arguments both ways. Ask yourself how you would like to live the rest of your life never being able to speak to, wave to, smile and laugh with or hug another human and then tell me if you think the human emotions for these things should be assigned to this topic/ situation given that birds do not feel emotions the same as us.
I can not answer this correctly for you- only you can
