Training cockatiels can be fun and easy as long as you go about it with the proper attitude and a bit of patience. In general, cockatiels are quite agreeable as pets. They are friendly, not very temperamental and fairly simple to take care of. Just provide some food, water and a decent cleaning on a regular basis, and you will most likely have a happy bird.As with any animal, your pet cockatiel may have a few habits that are not so agreeable for indoor life. Screeching comes to mind here, as does nipping of the fingers and being antisocial with other family members. Luckily, training cockatiels to stop these annoying habits is possible. With a bit more effort, you can teach your cockatiel to talk too.
