Awwwr, I don't have picture of my budgies scanned yet, so I'll have to come back tomorrow and edit the post. However, here's the info on all three of them.
Velveeta is a female of around 8 years age, possibly older (to be honest I forget when I got her.) She is almost completely yellow with a small splash of green on the belly. She was given to me by my mother after she killed my previous 'keet via carbon monoxide (she was cooking and the stove's fume hood backed up). She wasn't banded, was a little older than most pet store keets, and was very nervous and bitey. We tried taming her up for a good year but she never took to people so we got her a mate, Sky, who has since passed away due to a cancerous tumor. She seems to be a very angry bird; she is always attacking her toys brutally, squaking, and flapping her wings. She also has an amazingly fast metabolism and no matter how much she eats remains fairly thin. She can not be let out of her cage, but is in a very large enclose - 4ft H, 3ft W, 2.5ft D. She says "pretty" and that's about it.
Sigma and Theto were adopted from a woman with Parkinson's disease; she had gotten to the point where caring for them was very difficult. Both were extremely overweight and living in a very small cage with no perching when we got them. Once we could assure that they were healthy, we tried them in with Velveeta, and though they got along for a few weeks, Sigma suddenly stopped allowing Velveeta to eat, so they had to be separated. They are both in the same size enclosure as Velveeta, and are now "neighbors" with her instead of roommates.
Sigma is the female; she is green and standard looking, much like a wild budgie. She is very domineering and agressive to her mate, but doesn't harm him. She simply wears the pants in our keet family. The woman claims the bird is only two, but by the condition of her cere I'd say she is much older.
Theto is the male; he is blue with standard markings and a bit of white on his belly. He tends to overeat, but thankfully Sigma usually chases him off after a bit. He is very shy and nervous. He is supposedly one year old, and has no legband as the woman's neighbor bred him.
I haven't bothered taming up my parakeets because I seem to get them when they are already older and not fond of people. However, they have each other, a finch, and two parrots for company, so I think everyone is pretty happy ^^ Hopefully I'll have some pictures for you by tomorrow.
