He is beautiful. The mealies I have known have been big gentle birds. We had blue-crowned mealies and the nominate (like Pepsi) and all of them were wild caught imports. Yet most of them were tame. I get the feeling that they have been neglected by breeders and I think that they may be difficult to breed anyway. Our pairs never produced. I would love to meet a hand fed baby mealy.
By the way I do think Pepsi is a boy. Of course I could be wrong but I think i see a tiny bit of red edging on his yellow crown feathers.
He's come a long way. When I first seen him his nails were growing completely around back into his toes, the beak was deformed, the feathers were so brittle and dry, the feet were very sore.
The vet did a great job fixing as much as he could, and we are slowly shortening the nails. Some feathers are still in bad condition especially at the back of his neck but he is looking good.
He came to me only eating sunflower seeds and human candy. Now he enjoys Harrison's pellets with fruits, vegetables, and assorted nuts and seeds for treats.
Well your good care certainly shows now. I hope you took some before and after pictures. I have seen a couple mealies with overgrown beaks. They have big, powerful beaks. I assume that in the wild they must use them a lot, probably cracking large nuts and a lot of chewing. Have you ever given him almonds? Most amazons I have known love them and they make a better treat than a peanut. Does he ever take a bath? If he doesnt you might want to start misting him everyday. But his feathers will never look like a bluefronts', they are darker naturally.
