The face of the male is yellow or white, while the face of the female is primarily grey or light grey ...
All cockatiel colour genetic mutations have the same calls. The male lutino cockatiels can talk, sing, and dance (shakes head, makes the wings heart-shaped, etc.) to attract female cockatiels. Lutino cockatiels appear as full body in color yellow with two orange circular spots around the ear and cheek area.
The chicks fledge after 5 weeks. [19] Cockatiels are the only cockatoo species which may reproduce by the end of their first year. The cockatiel's average life span is 12 to 15 years, [20] though in captivity and under appropriate living conditions, a cockatiel could be expected to live from 16 to 25 years. [21]

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]
It all began with the normal grey cockatiel as the wild type colour, the mutations started with the captive home breeding, It took about 100 years for the first mutation [3] to evolve, from the first captive breeding of cockatiels which was in France in the 1850s till 1951 which known the Pied cockatiel mutation as first mutation colour to be established in the United States.
