In the world today there are hundreds of pet parrot species. Many of which can be brilliant companions. For the sake of confusion I will include anything parrot like into the category of parrots, e.g. Parakeets. The most popular parrots are often budgies and cockatiels, but if you are looking for something different, there are many more to choose from.
Being the most popular pet bird, a budgie is a great pet for children or people who don’t have the time and money to care for a larger bird. They are cheap to buy and they require only a small/medium sized cage. Budgies can learn to talk although this is rather difficult, but they can be trained to do small tasks. Many owners like to keep them in an aviary or in a larger cage with many more budgies. They live for about 10 years.
Cockatiels are slightly larger and may require slightly more care and attention. It is said that they belong either to the crested parrot family or the cockatoo family. They require a medium sized cage and are quite cheap to buy. They live for about 20 years so a long term commitment is required.
