You rock!!!!!!!!!!!!! Your dusky is beautiful! How did you end up with him? They're pretty hard to come by.
I have a female WC pionus, about 15 years old, and she's awesome. She's the first parrot I ever owned, and I got her because they are known to be a great parrot for beginners -- absolutely true.
Are yours very active? Mine is mostly a perch potato, but super sweet to those she knows.
She started laying eggs about 7 years ago, and began feather plucking and barbering. I got her a "sock buddy" tshirt to stop the plucking and it worked well. When I take it off and she's in season she still plucks, but no longer barbers her wings.
Pionus are definitely underrated and under appreciated, and I suspect it's because their colours are not brilliant, and they're not the best talkers. Folks that don't even consider them are really missing out, as they are wonderful companions. I'd get more if I had more room, although I am quite a cockatoo fan as well. It would be a tough choice as to what to choose.
Thanks for sharing the pic of your beautiful dusky!
