| |  | A female "normal" has a grey face and more indistinct cheek patches. A "normal" adult male has a clear yellow face and bright red cheek patch. Normal is dominant to all color mutations (except dominant silver). All mutations are variations of normal grey plumage, and are caused by dilution, intensification, or absence of the colors found in greys.
