With the availability of the Whiteface mutation, the cockatiel's wide colour varieties are divided into 2 main classes (or series): Yellow base: with psittacofulvin (yellow and orange) pigments. White base: without psittacofulvin pigments; Some white-faced cockatiels have entirely white bodies and red eyes.
The cockatiel is now biologically classified as a genuine member of Cacatuidae on account of sharing all of the cockatoo family's biological features, namely, the erectile crest, a gallbladder, powder down, suppressed cloudy-layer (which precludes the display of blue and green structural colours), and facial feathers covering the sides of the ...
The blue-eyed cockatoo is easily mistaken for the yellow-crested and sulphur-crested cockatoos, but has a more rounded crest with more white to the frontal part, and a brighter blue eye-ring. The blue-eyed cockatoo reaches full maturity after 4 years and lives an average of 50 years. Blue-eyed cockatoo has been known to make demanding, but ...
Males typically have almost black eyes, whereas the females have a more red or brown eye, but this requires optimum viewing conditions to be seen. The differences between the subspecies are subtle. C. g. fitzroyi is similar to the nominate race but lacks the yellow on the ear tufts and has slightly blueish skin around the eye. C. g.
Several species have a brightly coloured bare area around the eye and face known as a periophthalmic ring; the large red patch of bare skin of the palm cockatoo is the most extensive and covers some of the face, while it is more restricted in some other species of white cockatoo, notably the corellas and blue-eyed cockatoo.

The birds needed food and water and some had medical issues, rescuers said.
The "albino" cockatiel also known as the whiteface lutino, is not the result of albinism. It is a breed that combines two genes of whiteface and lutino. 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. So it has all white plumage, red eyes and pink ...
The male white cockatoo usually has a broader head and a bigger beak than the female. They have brown or black eyes and a dark grey beak. When mature some female white cockatoos can have reddish/brown irises, while the irises of the adult male are dark brown or black. The feathers of the white cockatoo are mostly white.
