Hi. I have had a "wonderfully vicious" little parrot for some time. He lives to bite me, but I absolutely adore him. I can trick him into letting me pet him by reaching around behind his BF, a cockatoo, and he nearly swoons getting stroked, then he is SO angry/embarrassed when he discovers this wonderful feeling is from me and not his buddy! He was hand raised and is now 23yrs old. I was told he was a "Mexican cherry head, but in searching that, I think there must be another name they go by? Anyway, lately it seems to me he is slowing down a bit. Can anyone tell me their average lifespan, and what suppliments I might give him? He's had a varied diet all his life... Now, Roundybush as a base, and anything he wants off our dinner plates. I have a lot of fruit trees, so he gets all kinds of stuff I make with the fruit, including just plain fresh. I selfishly want to share/squeeze every day I can with this hateful little rascal. Any suggestions? Thanks!
