G. J. J. Bastiaan


Born on  February 14th 1957 in Wezep (The Netherlands).

From  his early youth, due to his father’s encouragement he was an avid bird  fancier.    In the early 80’s he developed an enormous interest in colour mutation  breeding and ever since he has become a passionate breeder of Ringnecked parrots and their mutations and later on also  other members of the Psittacula  family.

In 1992 their first book “Ringnecked  Parakeets and their Mutations” was published. Since this was a great  success, it was decided to write a follow up. The first lines for this book  were already written in 1998 and is available since 2004.
