In the Netherlands is a parrot foundation with a amzon parrot who is 91 years old and had a diet of sunflower seeds and peanuts!
I've been told to feed Harrisons pellets, but I don't get it, why there are birds on horrible diets who get very old...
So I give pellets, seeds, nuts, fruits, vegetables... Just everything.
I hope my parrot get at least 60 years old...
Then I am 76
