A parakeet is a small household bird. The usual colors are blue, green and yellow. Although they do chirp a lot they can be very enjoyable. If you can train them to whistle and sit on your finger or shoulder they can be very fun. Due to there smallness, when they fly they go very faster, It reminds me of a humming bird Also they usually sell for very cheap. And are very intelligent.
They get their intelligence from their cousin the parrot, unlike their cousin they sell for less, and are very smaller. If you choose to buy a parakeet you may want to buy it a another friend parakeet to go in the same cage, and toys to keep it happy. It's very important to keep the bird happy, if you cant buy another parakeet at least buy him/her a mirror, and it will think theirs another parakeet in their with it.
I did have two parakeets, a male yellow, and a female blue. But recently my male died, and my female got very unhappy and, I put a mirror in there and she was happy, just like when she had the male parakeet in there. I do not have mine trained, but she will sit on your hand. And she can whistle with me.
If you like The parakeet then I hope you get to see one in your life. If you want one it shouldn't be that hard to find one if you live in a big city, A good place to purchase one at is pet co or any other pet store, they eat very little.
