Corella is one of the most beloved types of domestic parrots in Russia. They are much larger than budgerigars, but at the same time they are quite unpretentious in care and can delight their owners much longer, since they live from 5 to 15 years. However, if you are not very well versed in parrots, when buying, you may be given a knowingly adult bird or, conversely, a very young chick. To avoid such situations, read the instructions.
Look at the parrot's beak. In adult birds, it is heterogeneous in color and darker, may have detachments or growths. Young cockatiels have a lighter beak without visible flaws or roughness. The color of the wax is gray-pink in young animals. You can also pay attention to the paws. In adult parrots, like the beak, they are much darker, while in young ones, on the contrary, they are almost pink with delicate scales and neat smooth marigolds. As the bird matures, the toenails coarse and grow back, and the color changes to grayish or almost black.
Take a close look at the feathers on the bird's head. If the parrot is an adult, all the feathers of the tuft will lie flat, beautifully curving towards the end. Young parrots still cannot boast of their fully formed plumage, which is why they can be easily distinguished from adults by feathers on a tuft. If on the crown of the parrot all the feathers are straightened, and there are not very many of them, this is a sure sign that the bird is young. You can also notice in the gaps between the feathers of the crest of young parrots, tubes from new feathers that have not yet unfolded.
If you are looking to acquire a mutated cockatiel, it is quite difficult to determine the age based on the shape and size of the feathers. Therefore, you will also have to look at the wax and paws. The coloring of parrots of these breeds is fully formed only by the age of 2 years, so until this time it is very difficult to determine exactly how the final adult plumage of the bird will look like.
