The male normal grey, shown here, has dark grey feathers over his entire body, excluding the white wing bars, yellow face, and bright orange cheekpatches. This is considered the “wild” coloration of the cockatiel since most cockatiels in their native Australia have this coloration.
Immature normal grey cockatiels of both sexes look a lot like female normal greys….they have grey faces and dull orange cheekpatches, and their tail feathers have a white or yellow barring on the underside.
If you see a few white or yellow feathers on the back of your normal grey cockatiel’s neck and head, it means that your cockatiel is carrying one gene for the recessive mutation “Pied.”
Normal Grey is the natural color that cockatiels are in the wild. A mature male will have a dark grey body everywhere except for the white stripe on each wing, the bright yellow face and crest, and the orange cheek spot. The tail may be lighter than the body, but it is still a clear grey color.
A mature female as well as all immature birds (immature males will look this way too, it is only as they mature that the become like the above description!) all have the same grey body and white wing stripes, but they will have a dull yellow face and orange cheek spots. Often it looks like it’s a yellow �wash’ over their heads, which can look almost greenish. They also have yellow �barring’ on their tail and lower bodies. The under-most pair of tail feathers has the most obvious barring, with the rest of the tail feathers having less, but still obvious, stripes and dashes.
All colors may or may not have spots on the long flight feathers on their wings. Some have only a few feathers with spots, some have none, and some have a lot.
