@dlowan,
Domestication has given different colours:
Damn cockatiel go onto this one!
Babies only a mother could love...and yellow budgies:
When I was growing up, everyone had a budgie, or numbers of budgies. They can be enormously bright and talkative...one learned to play soccer remarkably well.
They are remarkably friendly, social, cheerful little souls. Ours used to fly free inside every night, and would love to come and nestle on our heads or shoulders and chat to us.
