Greening, who currently has about 50 budgies in his aviary, said many people remembered the budgies their grandparents kept in cages in their front rooms, which were mainly blue.
But he said there were also larger exhibition budgerigars and newer mutations, including the Blackface and Blackwing.
Budgies on display on Saturday included the Texas Clearbody, the Spangle and the Cinnamon Blue.
Stages were put up for the event and judges travelled from Southampton to assess the birds in their show cages, Greening said.
“The initial thing that the judges will look for is the condition of the bird,” he added.
“Is it fit? Has it got all its feathers? Does it look good?”
Owners arrived with their birds from about 10:00 BST, with judging starting at midday and the event was open to the public from 14:00 to 16:00.
