Dr Alain Campagne has been keeping birds since the 1970s and since 2000 has been seriously involved in the breeding of Neophema and Neopsephotus species. He is one of the growing number of 'modern' aviculturists who have embraced the internet and participates in international forums. These global discussions have evolved and expanded with the internet and have been the impetus for the universal naming system for parrot mutations now in widespread use around the world.
