In association with NBvV (Nederlandse Bond van Vogelliefhebbers), a well known and respected bird society in Holland, and PS Holland, well known for it's promotion for Psittacula Species (Werkgroep "Edelparkieten"), a new standard is being developed for the Psittacula species. The standard is used for judging these birds at regional shows. A large part of the development are the mutations especially the mutations of Ringnecked parakeet. Most of the mutation names are not based on solid arguments or genetics. With a little help from Inte Onsman, Mutavi Research, the mutations got names which are based on scientific and genetic arguments.
All the names which are used on this site for mutations are based on this standard.
