Actually, this is not a mutation. This is the most common form in natural life with natural colors. The entire body of this species is covered with dark gray. There are symmetrical white bars on the wings. Black spots appear on a part of the beak and nails. The cheeks have orange spots. Different colors are not found on the back or chest of a pure gray cockatiel. Until the first molt, their faces and bodies are the same color. In the first molt, the face of the males turns yellow, while the females remain gray. Since there are no mutations of this kind, it is possible to easily distinguish males from females. Males have stunning yellow faces and females have a gray color. Males and females up to about six months, look the same. So, to distinguish genders before this age, you need to evaluate their behavior and mutations. If you are still unsure, you should have a DNA test as the last option.
This type of cockatiel is the same as Normal Gray. Their grey portions are lighter, brownish, and the blackness of the foot and beak will be little or no. In this mutation, the sex of the bird can be identified after the first molt, around six months. In the molt, the males lose their pearls and replace them with their basic colors. The male's face turns yellow at first molt while females remain gray.
It is one of the most popular species of cockatiels. There is no color other than yellow and white on their bodies. They can be either completely yellow or completely white or half as well. There are even Lutinos who have only a yellow body. But no matter what, they have orange spots on their cheeks. Some Lutinos have red eyes. It is very difficult to distinguish between male and female. There are light bars in the feathers under the wings of the females, but in some birds with very light feathers, errors are made in the prediction of gender because these bars cannot be seen. The final result is a DNA test. You can get Albino (all white) puppies from Lutino and White Face mating so it is a preferred mutation by the breeders.
This mutation has a gene that does not present in others. Thanks to this gene, they can contain two colors in one feather. There are mutations with different proportions in the Pearling feature. Especially different breast colors emerge from different mutations. However, the common point is the graying feather on the back and wings. These feathers disappear in males at the first molt. Male Pearls are often confused with Cinnamon or Normal gray, but it is seen that they do not lose all their graying feathers. Pearl feathers remain especially under the tail and on the neck. The female Pearls, on the other hand, continue their lives with these feathers. These feathers begin to disappear in males with the first molt, and this is the most important detail for sex discrimination.
This is actually a Cinnamon and Lutino crossbreed. However, it is now accepted as a mutation because it is very common. In addition to carrying different shades from yellow to white like lutinos, they have symmetrically gray feathers on their wings. The amount and shape of gray feathers vary. There are orange spots on the faces of these tiels. Gender prediction is impossible by observation. DNA testing is required for a definitive result.
This is actually a sub-mutation derived from Normal Gray. But there are now too many of these mutations. In all Silvers, the head is yellow, the body is gray from the lightest shade. The feet and beak are pink and black-free. There are yellow bars under the female feathers. Thus, the female-male distinction can be made by observation.
This is the mutation that many of us admire the most and want to have. There is no orange spot on the face because this mutation genetically blocks lipochrome and psittacine pigments. This is the only one that does not have orange spots on its face. The whole body of these cockatiels is covered with gray feathers. In males, a white face appears after the first molt. In females, the face is still gray. However, they do not have orange cheeks in any way. In this mutation, we can determine the gender by looking at their face. By the way, this is my favorite one!
Silver White Face
It is undeniably the most valuable and rare mutation. It is the second stage mutation of Albino and Silver crossbreed, which is not guaranteed to be in this way. It is very rare and gender cannot be determined by observation. DNA test is the only way. This my dream one. If I see one of them around, I will catch it!
It is the second mutation of Lutino and White Face crossbreed. It is completely white and its eyes are red. They are wonderful birds and rally eye-catching. There is no chance of gender prediction with color separation. DNA testing is required for this purpose. It is a rare and valuable mutation. If you see one around, just keep it!
