Some of the Chapters in this book:

• Cages, Flights and Equipment
• Common Ailments and Diseases
• Pets
• Preparations for Breeding
• Color Mutations and Breeding Expectations
• Breeding
• How To's
• Showing
• The American Cockatiel Society Show Standard

Great tips and advantage from the author that had her own birds as constant winners.  I found that this book really helps explain the mutations, the how and why and what you get from the mix.  A great book for everyone wanting to breed cockatiels.
