Acquired: Pet store

Two budgies, Tommy and Tiffany (a male and a female, obviously!) were members of our pet family when I was young. They were great birds -- easy to care for, healthy and sociable, with fairly low aggression. The male was aggressive on a few occasions over the years, but only in small ways. The female was very docile.
These birds were non-destructive, easy to care for, and not bothered by the presence of loud children in the home, or even the presence of the cat (though we kept the cat in another room when the birds were out, of course). They weren't shy of us and could fly freely around the apartment without issue (often coming to sit on us).
While not as bright as larger species of parrot, budgies are still very intelligent and my father trained them to do simple tricks, even 'talk' to us, and though they never got the hang of forming the words that fluently, it was still very cute.
I wouldn't recommend this species as a pet for young children simply because they are small and delicate, but they seem to be okay in a home with kids as long as interaction is supervised.
