Normal

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.
