Description
It all started with the Normal (wild type) Cockatiel. At the time of this writing, we currently have fourteen (14) known mutations in the U.S. Of these mutations, six (6) were established in the U.S. All Cockatiels, excluding the Normal Grey are mutations. A mutation is defined as a spontaneous change in the genetic code. These changes have resulted in the color variations we now have today. Kerr identified Cockatiels (Nymphicus Hollandicus) in 1792 in their native country, Australia. The Cockatiels made their way as captive birds to Europe in the early 1800’s. The first captive breeding of Cockatiels was in France in the 1850’s. From there Cockatiels spread worldwide. It took about 100 years for the first mutation to evolve from the Normal, which was the Pied, in 1949. This eBook is fully detailed with illustrations showing the beauty of each of the Cockatiel Mutations found in the United States of America.
