The Pied cockatiel carries very wide variations from light to heavy-from pearl pied
to cinnamon pied, the markings are so varying with this particular mutation.
It is impossible to visually determine the gender of a pied cockatiel because male and
female look alike with no real physical characteristics to decipher the difference
between the two; so one might tend to rely more upon personality factors and traits or even have a pied dna sexed to be 100 percent sure of the gender. Sometimes the pearl-pied would be more possible to try and visually sex because the same rule of thumb
would apply that the male when he molts in most cases will lose a lot of his pearling; however the stronger strains will keep some pearling. I find the pied cockatiels are not only an extremely attractive and gorgeous fid but they are also a very intelligent mutation and are very verbal. I have had young 10 week old babies
sing and whistle up a storm. I find they are a very laid back calm mutation.
