"Well, there is help on
the horizon and
anyone seriously
interested in color
genetics should take a
look at Linda Rubin's
book:
COCKATIEL
G
ENETICS MADE EASY!
Though this book is
primarily directed to
breeders of cockatiel
mutations, there is
enough information in
this little volume to
teach anyone the
secrets of dealing
with recessive,
sex-linked, and
dominant mutations..."

SPLIT PIED
Split Pieds carry "tick" markings that include yellow or white splashes
of color upon areas of their head, crest, face, nape, or chest. Some
splits carry only a small marking; others may be heavily ticked.  


It is completely normal, for Normal Grey female cockatiels to carry
small amounts of yellow upon the face; usually the yellow markings
are small and occur under the chin, around the lores (between the
eyes and beak), and around the eyes or crown. It is the male, of
course, that carries the extended full yellow facial mask. In some
lightly Pied birds, these tick markings can be misleading as to whether
a bird is truly Pied or merely split; often test breeding is necessary.  
Read “Ticked Markings & Split Pieds” for additional details.



LIGHT PIEDS
In order to qualify as a Light Pied, there is usually at least one, or
more, yellow or white flight feathers and usually some yellow or white
feathers also on the rump. In better marked Light Pieds, the primary
flight feathers are "clear" (yellow or white) along with the central tail
feathers and possibly other areas such as the head or part of the
chest or lower abdomen.



HEAVY PIEDS
The autosomal recessive Heavy Pied is the Pied many exhibitors try to
achieve. It may vary in its pattern, which ideally should still remain
symmetrical (one side being the mirror image of the other side). The
amount of yellow, white, or cream-colored wash should approach 70%
of the bird, or higher (i.e., 70-97%). The face is expected to be clear,
just as ALL clear flights and ALL clear tail feathers are equally
expected to be free of grey.



CLEAR PIEDS
The autosomal recessive Clear Pied is a super, extra-heavily washed
Pied that is nearly 100% yellow, white, and/or cream, with perhaps
one or more dark feathers on the rump, back, or undersides. Because
the eyes are dark, the Clear Pied can be distinguished from Lutinos
even when viewed from the front. Enough Clear Pieds are produced
today to warrant a separate class for them in the Pied sections.


Hence, the three main classes for pied birds in both the novice and
advance sections are now written as:
Pied, Heavy Pied, and Clear
Pied
:


Pied: Cockatiels with less than 70% Pied wash (e.g., light pieds,
medium pieds, etc.).  This is the class already contained in the
Standard. It remains in order to inspire exhibitors to continue working
with Pieds, just as they do today. Some excellent Light Pieds are
instrumental in working towards producing well-marked Heavy Pieds of
markedly improved size and skull width.


Heavy Pied: Cockatiels with a melanin-free wash falling between 70%
-97%


Clear Pied:   Cockatiels with a melanin-free wash, 98% - approaching
100% (e.g. Black-eyed Clears once known as “bulls-eyes”).



Today, the popular Pied varieties also include classes for Heavily Pied
birds, and a catch-all Clear Pied class, for both the Pied sections (e.
g., Cinnamon Pied, Pearl Pied, and Cinnamon Pearl Pied), and the
Whiteface sections (e.g., Whiteface Pied, Whiteface Pearl Pied, and
Whiteface Cinnamon Pearl Pied) at cockatiel shows. Although these
classes relate to exhibition, they are useful as a guide to classifying
what type of Pied you own.
