Birds can live for "decades" (not just parrots?) That's a new thought. I would have thought the local population of birds only survived a few years. That would make sense then why they avoid Bowser's friend.
Crafty little buggers.

Last spring while still in Florida, we had some hellacious rain storms that blew a nest of baby bluejays down and some, barely a few days old got thrown out on the ground. The cats got most of them, but low and behold there was one on the ground the very next morning. I picked it up to dispose of it (the fire ants would come in and clean it up and I don't want those anywhere NEAR the house), and this baby bird was still alive and very, very cold. I was amazed it had survived at all. It's mother dived at me when I went to pick it up. Then issued an alarm to it's mate.

I took it in the back porch and warmed it with my hands then found a round plastic tub to put it in with some grass and then tied it back up in the tree with a ladder. The mother bird kept diving me, but she called to it, looked at it, then eventually started feeding it. Then dad bird came around and they were VERY protective of it. I'd check on it every day, and it was still squawking. Another heavy rain came and I KNEW the plastic bin was full of water and I was hoping it wouldn't drown. I got out after the rain and saved it again, this time pouring out the 3" of water and heading to the dollar store to find a cheap weaved basket, which I filled up with grass and exchanged for the plastic bin (all the while being dive bombed by the parents). THIS worked beautifully. It was deep and mom could get in there. The blue jay survived and after he learned to fly would come sit very close to me on a branch while I was gardening or follow me part way on my walks.

I laughed at myself for taking such care of a nearly dead, cold, featherless baby bird when the rest of the world is in major destructive mode, but the sight of it watching me, preening itself closer than any other birds around the yard (birdhouses and bird bath around) was rewarding enough. It knew, and was probably just as curious about me as I was about it.
