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. Once cockatiels have gone through their first molt at six to nine mutationdthe adult coloration shows, although at that time they don’t attain their final adult coloration.

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 Lutino is a yellow-white bird with orange cheek patches and red eyes. Pearl cockatiels are not unique they’re a dime a dozen.

Eventually they will lose all of them until they look just like normals. This mutation was obtained from the Charcoal mutation. Also note that a white face pied will have white mugations instead of the yellow, as well as the white face pearl will have white speckles.

Facial Variations OK, so that’s the colors and the markings! Mutayions information is also provided whenever available.

The only Mutation this can truly be done on is Adult Normal Grey’s, and it is because the Adult Male gets a full yellow head the female doesn’t – so there for a female would have a “dull” face, this also works in Normal Cinnamon’s – same way – males get full yellow heads, females don’t. When mutatios pieds coxkatiel may or may not get heavily pied young from heavily pied parents.

Remember, we were only talking about the main color of the body; there are other mutations to talk about yet! The charcoal is recessive and when bred with the lutino it will eventually produce the pure Albino.


So you hear about these different colors and patterns, but how do you tell them apart, and more importantly, what type is YOUR bird!? Males tend to strut around – they lift their wings slightly, stick their chest out and parade and strut, normally calling at he same time.

Cockatiel Mutations

So tiels can, and do, come in a huge and gorgeous tiel rainbow! The recessive silver is a light silvery color, much like a pale normal grey, except they have the same red eyes that fallow and lutinos have. There is a great difference in color variation in fallows. The silver is noted for poor eyesight.

The male and female, as well as the immature tiel all have the same coloration and markings. Species Research by Sibylle Johnson. The olive cockatiels have a scalloped pattern in their feathers, with the outer edges of each feather being darker than the centers, making each feather seem outlined in a faint fockatiel design.

From outward appearance the cocks look like normal birds after the first molt. Their faces do not turn yellow, and they have either white or yellow barring on the underside of their tails. Before I go, I’ll touch briefly on the fact that the mutations can double, triple, and quadruple up!

Pearling in a whiteface cockatiel is always white. Never breed visual Fallows together. Please contact them directly with respect to any copyright or licensing questions. White pearling is sometimes called Silver Pearl. There are occasional claims of other colors, and many of the colors have other names, but these are the colors and names that are recognized by all the cockatiel and bird societies.

The bald spots were especially pronounced when the lutino mutation was first bred and in the following years after that. The adult white face male will get a bright solid white head after he has his first moult. The silver mutation occurred in Europe in the late 60’s. Kersh in and she was still working with this mutation, and I might add, they were outstanding in color.

A bird may be “split” to a mutation but not visually display it. In females, barring is visible on the underside of the tail. White Face is a stunning, fairly common mutation. The tail feathers have a white or yellow barring on the underside. I have had one case where feather growth problems occurred in the offspring. A bright-faced pied tiel does not make it a male, nor does a dull-faced pied tiel make it a female. Sexing must be done by behavior.


Though it has been bred through to the offspring, I do not believe this is a mutation. This mutation will certainly change the cockatiel world in a few years because it is so radically different than the previous mutations. It can vary in its exact pattern on the feather, some being a heavy lacy pattern, others being a light spotting.

Cockatiel Mutations

This beautiful whiteface mutation lacks the orange cheek patch and yellow pigmentation. Some are a very obvious brown color too. Feathers have a green wash and a light spangling pattern. Cockatiel females and young birds have barring on the underside of the tail as can be seen above.

Once this is obtained a breeder can breed the pearl out from the mutation. So I will stick with You can cockatlel tell if a Cockatiel is split to pied. That you can sex cockatiels because of their face – a tiel with Bright cheek patches is male, one with dull cheek patches is female. Still, they typically have enough to make some sexing possible.

This all makes this method of sexing “iffy” at best. 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.
