Genetics and Heredity: Color Mutation Studies Of Parrots And Finches.

Above is the normal red-headed Gouldian.

Here is a dilute cock. Only males can show dilute as this is a partial dominant sex-linked mutation. This Gouldian is blue-bodied but also has the dilute factor seen in the previous photo. This hen shows the recessive white-breasted mutation and is also black-headed.

Above are examples of basic body color mutations seen in the Gouldian finch. each mutation is a result of controlled breeding and, though interesting, represents protein utilization deficiencies.

As seen in the photos below, aviculturists are discovering many parrot species are inherently prone to very similar genetic mutations of colors and patterns. Different kinds, such as parakeets, ringnecks, parrotlets, conures, lineolateds, Amazons and more are producing Blue, opaline, pied, cinnamon, dilute and others.  Breeders are delighted when different color combinations show up. Newer colors within a species have a great impact on the financial value of the bird.

Fledgling parakeets like this one can make good pets. Note the black eyes and stripped forehead.

Parrotlets are among the smallest known species of parrot. These Celestial or Pacific parrotlets are bred in many colours.
