The cockatiel's distinctive erectile crest expresses the animal's emotional state. The crest is dramatically vertical when the cockatiel is startled or excited, gently oblique in its neutral or relaxed state, and flattened close to the head when the animal is angry or defensive. The crest is also held flat but protrudes outward in the back when the cockatiel is trying to appear alluring or flirtatious. In contrast to most cockatoos, the cockatiel has long tail feathers roughly making up half of its total length. At 30 to 33 cm (12 to 13 in), the cockatiel is the smallest of the cockatoos which are generally larger at between 30 and 60 cm (12 and 23.5 in).

The "normal grey" or "wild-type" cockatiel's plumage is primarily grey with prominent white flashes on the outer edges of each wing. The face of the male is yellow or white, while the face of the female is primarily grey or light grey, and both sexes feature a round orange area on both ears, often referred to as "cheddar cheeks". This orange colouration is generally vibrant in adult males, and often quite muted in females. Visual sexing is often possible with this variant of the bird.

Cockatiels are relatively vocal birds, the calls of the male being more varied than that of the female. Cockatiels can also be taught to sing specific melodies. Much like parrots, but not quite to that extent, Cockatiels can be taught to repeat words spoken by human owners.

Sexual dimorphism[edit]
All wild cockatiel chicks and juveniles look female, and are virtually indistinguishable from the time of hatching until their first moulting. They display horizontal yellow stripes or bars on the ventral surface of their tail feathers, yellow spots on the ventral surface of the primary flight feathers of their wings, a grey coloured crest and face, and a dull orange patch on each of their cheeks.

Adult cockatiels are sexually dimorphic, though to a lesser degree than many other avian species. This is only evident after the first moulting, typically occurring about six to nine months after hatching: the male loses the white or yellow barring and spots on the underside of his tail feathers and wings. The grey feathers on his cheeks and crest are replaced by bright yellow feathers, while the orange cheek patch becomes brighter and more distinct. The face and crest of the female will typically remain mostly grey, though also with an orange cheek patch. Additionally, the female commonly retains the horizontal barring on the underside of her tail feathers.

The colour in cockatiels is derived from two pigments: melanin (which provides the grey colour in the feathers, eyes, beak, and feet), and lipochromes (which provide the yellow colour on the face and tail and the orange colour of the cheek patch). The grey colour of the melanin overrides the yellow and orange of the lipochromes when both are present.

The melanin content decreases in the face of the males as they mature, allowing the yellow and orange lipochromes to be more visible, while an increase in melanin content in the tail causes the disappearance of the horizontal yellow tail bars.

In addition to these visible characteristics, the vocalization of adult males is typically louder and more complex than that of females.

Colour mutations[edit]
Main article: Cockatiel colour genetics
Worldwide there is currently twenty two (22) cockatiel colour mutations established in aviculture with eight being exclusive to Australia. Mutations in captivity have emerged in various colours, some quite different from those observed in nature. In 1949 the species began to spread throughout the world, with the creation of "wild", and then "pied" mutation developed in California. There are many mutations of cockatiels with varied colours, they are: fallow, lutino, cinnamon, emerald/olive, dominant and recessive silver. mutation exclusive to Australia are: Australian fallow, faded (west coast silver), dilute/pastel silver (east coast silver) silver spangle (edged dilute), platinum, suffused (Australian olive) and pewter. pattern altering mutations such as pied and pearl. other mutations such as face altering mutations include; whiteface, pastelface, dominant yellow cheek, sex-linked yellow cheek, gold cheek, creamface and the Australian yellow cheek.
