Cockatiel Mutation

Cockatiel Mutations   ANCS Colour Standard 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      HEAVY PIED (Recessive Pied) 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 female heavy pied                 Adult male cinnamon heavy pied WHITEFACE HEAVY PIED (Recessive 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                LIGHT PIED .(Recessive Pied)   More than 25% dark grey with grey flights and tail feathers allowable. Grey and yellow is to have good definition. Grey feathers permitted in face area. PEARL. (Sex-linked Opaline)   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 LUTINO. (Sex-linked ino)   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. CINNAMON. (Sex-linked cinnamon)   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. HEAVY PEARL-PIED.   Same as for heavy pied with even pearl feather pattern on the non-pied markings. LIGHT PEARL PIED.   Same as for light pied with even pearl feather pattern on the non-pied markings. AUSTRALIAN FALLOW.   A light cinnamon colour suffused by yellow, which is very evident on chest. The eyes to be clear red. Flesh coloured feet and nails. PASTELSILVER (RECESSIVE) (Dilute)   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 normal. WHITEFACE. (Blue)   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. PLATINUM. (Sex-linked Parino))   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. PASTELFACE.(Paleface) (Parblue)   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.     SPANGLE (Edged dilute)   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.       AUSTRALIAN OLIVE (Suffused)   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. PEWTER (Pewter) 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. WESTCOAST SILVER (Faded) Grey with brownish tones that is slightly lighter than the normal grey. Feet and beak also lighter in colour. MULTI MUTATIONS.   Are many and varied and will be judged by combining the mutation specifications relevant to the particular multi mutation.
