White faced cockatiels-the colors are sex linked

Recessive genes require one copy of the gene to be passed down from each parent to the offspring so the offspring has two copies. Recessive genes are inherited the same way regardless of the sex of the bird. The male bird must receive one copy of the gene from each of his parents. Male birds pass on one copy of their sex-linked genes to both their male and female offspring. Female birds require only one copy of a sex-linked gene to visually show the mutation in their coloring.
