Query: An archaic collection of cockatiel information.

Having bred and raised cockatiels for 13 years, I can unequivocally state that this book contains little or no helpful information about cockatiels. In fact, there is a great deal of misinformation. For example, the genetics section contains incorrect information regarding the breeding of albino cockatiels, treating albino as if it were one gene instead of a combination of lutino and whiteface. Another good example of Mr. Vriend's use of archaic information is that he recommends peat moss in the nestbox, which can cause fungal growth leading to aspergillosis, which is a serious lung disease.My recommendation: read a book written by someone who has recently bred cockatiels.
