Q. My 15-week-old cockatiel is a Pearl mutation and so far I think she's
female.  If she is not female will she lose her pearl lacings and then what
will “she,” rather “he,” be considered ... a Normal Grey? If this does
happen, when can I expect it to happen? – Lori


A. Hi Lori,
According to the pictures you posted it appears you have a Cinnamon
Pearl, rather than simply a Pearl, because the color is closer to
Cinnamon than to Normal Grey.


Although the majority of adult Pearl males do eventually lose their pearl
lacings, there are some breeders who are working to selectively breed
Pearl males that retain some lacings. This is rather a difficult task to
undertake unless most breeders cooperate when contributing to the
gene pool at large. However, there are some males that retain their
lacings, or partial lacings, for a number of years and possibly throughout
their lifetime. I have found this to be congruent within my own aviary.


In accordance with many show standards, judges will reward adult Pearl
males that retain clear pearl lacings. The goal is to encourage more
breeders to selectively breed males that retain their pearl lacings and
pass this inherent genetic ability onto their offspring.


Upon full adulthood, or by the second or third adult annual molt, many
Pearl males will lose their pearl lacings and become indistinguishable
from Normal Grey males. Yet, to my eye, many of these Normal Pearl
males take on a very deep, dark, rich grey “charcoal” color, which can
sometimes be darker than many Normal Greys.


Of course, because you have a Cinnamon Pearl - should it be male –
after its adult molt it will appear indistinguishable from adult Cinnamon
males. If your Cinnamon Pearl male should also carry any clearly defined
pearl lacings, it would be more desirable.  


It is unfortunate that a number of Cinnamon males have a lessening of
melanin (Cinnamon) pigment on their backs, creating a “marbling” effect,
which is actually a show fault. This “marbling effect” or show fault of
Normal Cinnamons should not be confused with adult Cinnamon-Pearl
males that retain some true pearl lacings beyond their juvenile molts.
