Pearling was first seen in 1967. This is seen as a feather of one colour with a different coloured edge, such as grey feathers with yellow tips. This distinctive pattern is on a bird's wings or back. The albino colour mutation is a lack of pigment. These birds are white with red eyes. Fallow cockatiels first appeared sometime in the 1970s.
The pearl cockatiels' gene does not have any visual effect on the colour pigments in the bird but instead, it affects the distribution of the colours that are already present. It actually decreases the spread of the grey family of pigments ( melanin ) and increases the spread of the yellow pigments (psittacofulvin).
The "albino cockatiel" is not a true albino, it is a combination of a "white-faced cockatiel" and a "Lutino cockatiel". The "Whiteface gene" removes all the yellow and orange that would be present in a Lutino. and the "Lutino gene" removes all the black and grey. The result is an all white cockatiel with red eyes. [4]
These birds are very long-lived, and can live upwards of 70 years in captivity, [13] [14] although they only live to about 20–40 years in the wild. They have been known to engage in geophagy, the process of eating clay to detoxify their food. These birds produce a very fine powder to waterproof themselves instead of oil as many other birds do.
