Today, there are a little over 3,000 members of the Budgerigar Society Photograph: Asadour Guzelian for the Guardian

The average age of breeders at the show is somewhere around 60, and what few new recruits there are come almost exclusively from budgie-fancier families Photograph: Asadour Guzelian for the Guardian

There are 90 different trophies to be won, with categories for breeders of every aptitude from beginner to champion, and birds of every colour, from albinos and cinnamons to sky blues and opalines Photograph: Asadour Guzelian for the Guardian
