I would like to adopt another parrot someday, but I think it would be very strange to adopt something older than you. Parrots can live to be 60+, so I could someday be the guardian of an animal who lived a few decades before I was even born and that’s just weird.
I don’t think I have the authority. By default, that bird should be my guardian.
There’s a similar problem with tortoises! I own a tortoise that is, bare minimum, five years older than me, and it’s a confusing mix of “you should be able to explain taxes to me but also you’re basically an anxious baseball”
