Cockatiels are amazing pets as well as companions. They live pretty long and are very smart birds. If you interested in adopting a Cockatiel, they require attention and responsibility. If you love spending time with cute animals then I think you will like Cockatiels. If you have any other pets, do not assume they will get along because they might just not like each other.
Try to find out as much as you can about Cockatiels. The more you know about Cockatiels, the better you might be able to get along with your bird. Simply learning about the things it does not like and the things it likes, can really help with you bonding with your bird. Cockatiels are inexpensive pets and great friends to have around. I hope this helped!
