Cockatiels are native to Australia, where they are found largely in arid or semi-arid country, but always close to water.
What do you expect from your Cockatiel? When you bring one home, you expect him to be a “cuddle bug,” possibly a talker, be intelligent, sociable, and give you unconditional love and companionship. This is what you want and this is what you can have, with exception of talking in females. Males are the ones that are trainable to talk. Rarely do females talk. You need to treat your Cockatiel the same when you first get him as you would a year from now. They are intelligent and can give you much pleasure and fun. They will love you like no other. Any family members, neighbors, and even strangers will be able to come over and pick up the bird. You will want for the whole family to be able to pet the bird. They bond very strongly to their owner. In my experience, they can be great with many people.
