Mutations when talking about cockatiels simply refers to the color of your tiel. The picture above is a picture of one of my babies..I call him Tiny because he is so small..he is a pied and as you can see he is a real sweet heart and just loves to have his picture taken. Some mutations are harder to come by than others and some mutations are more expensive to obtain than others. For the sake of a quicker loading time and easy to follow guideline I will provide each mutation with its own page...All you have to do is click on the link below for the mutation and you will be able to see pictures of that mutation. I will try my best to supply pictures of both male and female with each mutation.
