My very first budgie I named White Waters. His colors reminded me of the colors of rapids, but he had a very sweet personality. My third budgie was named Storm Cloud. I actually recall looking up at a tiny dinky white cloud up in the sky, and the name "Storm Cloud" came to me! She was a blue budgie with a feisty personality! It seemed rather fitting!
I've also had Neon that was a bright green opaline budgie, Saffron, a mostly yellow budgie, Taxi because his green colors somehow reminded me of a taxi, Violet, well, Violet was violet! Also a Casper (all white budgie). Had a pair of budgies given to me named Cosmo and Sunshine.
Other budgies included Smurf (came with the name, blue budgie), Georgia & Sophia (both came from a Las Vegas breeder, so I was thinking names for show girls), Normie/Normand and Sora (sky). There's a couple of names I'm forgetting at the moment.
There was also Peachie, a peach faced lovebird that came with her name.
Casey, my tiel came to me with her name, as did Pistachio and Kiwi. Tomi Girl was given the name 'Tom' but she was no "tom"! I don't know what her original name was, if she had one. Faye was another I gave the name to, which kind of coincided with when I was reading stories about Merlin/Excalbur/Morgan le Fay aka Morgane/Aurthor/etc. Morgane was actually evil, but Faye is a sweet bird!
Noel (cherry head conure) came to me with that name, and well.... he was a red and green bird! Charlie, mitred, also came with his name.
Some are unique, and others aren't. People thought that White Waters and Storm Cloud were Native American names, and often wondered if I was part Native American (I am, but not enough to count!).
