Didier Mervilde of Belgium has an interest in the ‘Rare’ varieties and breeds Texas Clearbodies, Slates, and Spangles; besides also keeping Lovebirds in variety. There is a very interesting article with accompanying photographs on the Blackface budgerigar variety which came to light in 1998.

From Perth in Western Australia come the extensive and informative pages of Brett and Sharon; a committed partnership with a particular interest in the ‘Rare’ varieties and the genetics which lie behind them.

Website of a British breeder, newly returned to the exhibition scene, with pictures and information on the new stud he has assembled together with some excellent pages on genetics.

Maintained by a Danish threesome of exhibition Budgerigar breeders, this site features a good introductory section on basic genetics followed by a discussion on how to relate this to selective breeding for desirable exhibition features.

Originally developed by Dolores Noonan in the UK, these pages are now maintained by Joy... This is a large site containing a wide range of interesting articles previously published in various journals, but remember that many are by exhibition breeders who do not always distinguish between fact and fantasy.

Pages of John W. Evans a successful British breeder of exhibition type Clearwings with an extensive illustrated article outlining his methods.

Two lively societies, the first Cincinnati, Ohio, and the second from Ontario, Canada, which feature a range of articles and links.

From the state of Victoria in Australia, the pages of an area society and two of its leading lights.

These pages include a listing of the basic varieties with links to photographs of examples. There is also an introductory Cockatiel Genetics page which, I feel, attempts to introduce the subject too simplistically.

This society’s pages also include a listing of the basic varieties with links to some excellent photographs.

Another American National? society whose pages (slow to download) once again include a listing of the basic varietieswith accompanying clickable thumbnail photographs. There is also a genetics page but be aware that standard genetic symbolisation is not followed.

From down under this site features a range of articles including one by Mike Anderson outlining his views on the relationship between the Platinum and Lutino (Ino) after many years breeding these varieties together: Platinum and Lutino: Genetic Interaction.

Brought to you by Peter Klapwijk of British Columbia in Canada these pages belie the cute name and include some good photographs, information, and articles. Through no fault of the author the chaotic state with regard to naming some colour varieties and their composites is brought into sharp relief.

Elsie Burgin and husband Herschel produce this site which includes photographs of a wide range of varieties; in particular, some of the ‘Olive’ variation together with brief notes.

Nice pages of Anne-Marie Larzelere, a specialist breeder from Florida, which introduce this species as well as the Australian grass parakeets.

Although a relatively small national society, the BVA is very progressive and initiated discussions on the harmonisation of colour variety names. There is full information on all species of Lovebird and their colour varieties.

Hosted by Dirk Van den Abeele, Chairman of the above society, these pages have much information on Lovebirds with some emphasis on the particular feather features affecting colouration which these birds possess. In discussing the naming of colour varieties, on which there is ongoing discussion at Genetics-Psittacine, there is a link to the Mutavi pages.

An International, though based in America, Society devoted to the Lovebird species. There is a section dealing with the more established colour varieties and their genetics, but it should be pointed out that there is a mix of American and traditional terminology in contrast to the more up to date information carried by the two sites above.

Pages of Chris Rutt, a longterm British specialist in Lovebirds, which also reflect his wide range of other interests.

Site of the Peach Faced Lovebirds breeders in America who discovered the Rose Headed variety, which it is believed may be equivalent to the Opalines found in Australian parakeets. There is a good article Rose-Headed: A Possible New Mutation In A. Rosiecollis? by Doug Bedwell detailing the occurrences of this colour form and its subsequent establishment.

Nice pages of Anne-Marie Larzelere, a specialist grass parakeet breeder from Florida, with useful introductory information.

1. Introductory article The Five Popular Australian Grass Parakeets by prolific author Mathew M Vriends at the AFA website.( No link back to main page.)
2. Article Mutations in Elegant Grass Parakeets by Jim Chou. But note that the bird incorrectly described as “Yellow” is a non sex-linked (NSL) Lutino and that the European Cinnamon is a true sex-linked variety whilst the Australian may well be an incomplete- or par-ino. (No link back to main page.)

Informative pages on the members of this species produced by Brian Nielsen of Denmark with photographs and information on the colour varieties available in F. coelestis. There is also comment on the hybridisation which has taken place between F. coelestis coelestis and F. coelestis lucida.

Based in California, the Parrotlet Ranch is run by Sandee and Robert Molenda where they breed the Pacific and five other species of Parrotlet in wild form and in colour varieties. There are an informative articles on the different species and also an article “The Lost Lucida” on the little recognised sub-species Forpus coelestis lucida

From Georgia, South Carolina, these pages by June DiCiocco feature Conures and minature horses besides Parrotlets.

These Dutch breeders specialise in Parrotlets, Lovebirds, and Budgerigars, and illustrate many colour varieties of each species.
