This is a list of various
Australian cockatiel mutation types
with pictures and although needed to specify
each type, it is to be remembered that in the case of showing and judging, birds will be judged on
conformation as the main criteria, and mutation type will be secondary.
However birds must still conform to the specification for each mutation.
NORMAL GREY COCKATIEL
Body to be dark grey, uniform throughout. Males to have bright clear head
of deep yellow, with bright orange cheek patches. Wing patch to be well
defined and clean of darker feathers. Females and juveniles to be a duller
version of the male colouration, with barring on tail feathers, which is
absent in adult males.
Adult female normal grey
Adult male normal grey
Adult female normal grey
Ideally 75% yellow to 25% dark grey with clear (not grey) flights and
tail feathers. Grey markings to be as symmetrical as possible. Head area
should be devoid of dark feathers.
Bird may be any base colour.
Adult male cinnamon heavy pied
WHITEFACE HEAVY PIED
The same colour pattern applies as for the
Heavy Pied but the yellow is replaced with white. Head area, tail and
flights should be devoid of any dark colour. Bird may be any base colour
More than 25% dark grey with grey flights and tail feathers allowable.
Grey and yellow is to have good definition. Grey feathers permitted in
Hens…Well-defined heavy pearling is the aim with good depth of colour
in pearls and body.
Cocks... As for hens with less importance placed on pearl quality.
Most males moult out the pearl pattern on maturity. A ghosting is often
all that remains as evidence of the pearls
Ideally the bird is a uniform rich deep lemon yellow colour throughout,
with bright contrasting cheek patches of orange. Flesh coloured feet and
clear nails. Eyes are to be either ruby or red.
Rich uniform cinnamon colouration on entire body, with yellow head area
and bright cheek patch, with no blotching or mottled effect. Flesh
coloured feet, clear nails and dark ruby eyes.
Same as for heavy pied with even pearl feather pattern on the non-pied
Same as for light pied with even pearl feather pattern on the non-pied
A light cinnamon colour suffused by yellow, which is very evident on
chest. The eyes to be clear red. Flesh coloured feet and nails.
A diluted form of the normal body colour, which is best described as
silver grey. Colour to be uniform throughout. Eye colour is lighter than
As per the normal bird, but totally devoid of any yellow or orange
colouration. Birds are to be two colours only, dark grey and white. Cocks
to have pure white head with no dark feathers and good definition between
head and body colour.
A pale smoky grey colour with a yellow suffusion throughout the body.
Yellow head area and bright cheek patch. The smoky grey colour is slightly
darker on tail and flights. Feet and nails flesh coloured.
Same as for other mutations except for the yellow
pigment to be diluted to a pale lemon colour and the cheek patches to be a
pastel peach colour.
A dilute mutation with a striated, shaded appearance to
the feathers of the entire body. This is less noticeable on the head area. The
shoulders are darker but still show the striations and shadings. Beak, eyes
and feet are dark.
The colour is a suffusion of yellow and varying shades
of grey. Ideally the colour is lighter on the back than the front area with
the wings and flights even lighter than the back. Hens are generally darker in
colour than cock birds which become lighter with maturity. Juveniles have a
dark hood with the majority of birds moulting this out as they age. Hens may
retain the hood. Dark beak, feet and eyes.
Brown colour with greyish tones that is much
darker than cinnamon. Beak and feet are dark not flesh coloured like the
cinnamon. Hens are not usually as dark brown coloured as cock birds.
Grey with brownish tones that is slightly
lighter than the normal grey. Feet and beak also lighter in colour.
Are many and varied and will be judged by
combining the mutation specifications relevant to the particular multi
