There are three different types of genetic mutations in the Cockatiel. These are Sex-Linked, Recessive, and Dominant. The Sex-linked mutations are Pearl.

Both sexes appear the same before the first molt and are totally grey in color through the head.

Cockatiel Mutations

Where a normal adult male will get the bright head, and the female retain the dull head, in the pied mutation, the way a pied baby is when it is young, is the same as it’ll be when it’s older. After the first molt the male obtains a white-face. This is not a well developed mutation and is still somewhat new. Male birds have yellow faces with gold cheek patches. The main difference between them is that the fallow colored birds have deep red cockagiel.

Hens may also have slight yellow flecking on head. Your email address will not be published. Both sexes have those broad white bars along the occkatiel of each wing. As a result, there are many cockatiels sold as Fallows, by inexperienced breeders.

Many breeders of the rarer mutations, through communicating with each other, have learned to avoid introducing Pearl to Fallow when breeding because pearl tends to enhance an existing problem with balding. Males tend to be more vocal than females, whistling more than their female counterparts. Most will carry a very small amount of yellow on the base of each tail feather by the quill.

A skullcap of darker pigmentation is visible on the head. The body plumage can vary from a Lutino appearing bird with very pale warm beige wash to a soft light milk chocolate shade, with a deep yellow suffusion to the face and chest of both sexes.


A lot of the excitement for cockatiel breeding can be explained mutationw the many beautiful mutations that have occurred over the years. It can vary in its exact pattern on the feather, some being a heavy lacy pattern, others being a light spotting.

The colors are the same as the pied with the pearling only on portions of the wings. The unique thing about pied cockatiels is that even though it is a mutatons trait, a tiel can carry the gene for being pied, and pass it on to it’s offspring, without being pied itself you can see when a tiel is carrying the pied gene. Lutino Pieds would have darker yellow “splotches.

The generic pairing I observed would theoretically produce one female albino out of 16 babies. Remember, we were only talking about the main color of the body; there are other mutations to talk about yet!

Kersh in and she was still working with this mutation, and I might add, they were outstanding in color. All females will retain their patterning, making them often the preferred gender of this mutation! Males lose tail barring and get a yellow head.

Cockatiel Mutations | Beauty of Birds

Pearl Body is covered with a unique pattern of spots. The beak and feet are light toned, lacking melanin pigments, with the toenails appearing a pale tan. Even, symmetrical marking is desirable. Split pieds often show several white or yellow flecked feathers on the back of the neck.

The under-most pair of tail feathers has the most obvious barring, with the rest of the tail feathers having less, but still obvious, stripes and dashes.

Instead of the normal yellowish color, the charcoal has white down. Though it has been bred through to the offspring, I do not believe this is a mutation. Hopefully now you know mutatkons color your cockatiel is, and what markings it might have, now there’s the facial variations!


The Normal Grey is the original bird native to Australia. All yellow and orange areas on bird replaced with white. Pearl hens vary from light to heavy pearl markings, with the heavy, evenly marked bird being more desirable.

The Emerals Cockatiel, also known as Spangled Cockatiel or Olive Cockatiel, has small patches or splotching’s of varying yellow to grey colors. OK, so that’s the colors covered, by now you might have an idea of what color your tiel is. When breeding pieds you may or may not get heavily pied young from heavily pied parents.

Hens and juveniles have yellow barring on the tail. Whether it has a dull head, a bright head, or patches of both on it’s head and face, it doesn’t make a difference to what gender it is, and it will always stay the same. The charcoal is recessive and when bred with the lutino it will eventually produce the pure Albino. It is a bird that is a pale grey color, with a heavy yellow wash’ giving a distinct green-ish tone.

Pied is the only mutation that you can visually tell when a bird is split to it. A lot if inbreeding of this mutation caused this undesirable bald patch, which doesn’t diminish the tiel’s pet quality – but is not a desired trait for breeding. The bird was a female.
