You could have these little sweeties a long time. I was given an 8 year old turquoise and white budgie with major grouchy attitude.
He'd sat in a cage in a kitchen for years and the owner was now going away to University. Her words were something along the line of "He probably won't last another 6 months, these birds die around 8 anyways."
Hah. The kids had him out of that cage in minutes and he loved flying round our two storey townhouse. I'd find him asleep on bookshelves upstairs, atop doors, you name it. He had a major personality change within two weeks and became very friendly.
The dog and cats wouldn't go anywhere near him, he had them all terrified, he would puff up and screech like a banshee at them and then nip their sensitive noses and paws. He had them completely buffaloed. (yes, of course we watched closely anways) He lived with us until he was 12 1/2 and nearly pure white. We sure loved that bird.
He survived a stroke too. When he finally passed on from sheer old age it was in the middle of winter and I wanted to bury him in our yard but it was under 4 feet of snow and frozen solid like cement. So I reverently wrapped him securely in a large plastic bag and stuck him in the back of our refridgerator freezer to await softer ground. Which was fine but everytime I went in there for frozen peas I came out with the bird! I'd just say "Hi Princie" and stick him back in there again. Over that winter I almost saw him as much as when he was alive!
It totally grossed the kids out when they'd get him instead of the frozen pizzas.
Come spring I buried him under a nice tree in the yard. One great bird, we had a blast with him for many good years. I'm sure you'll love your little honeys too.
