The behaviour of budgerigars housed in aviaries in a group of 6, or caged individually was studied over 2 months. Budgerigars in the aviary consumed more food and were more active, performing more wing stretching and flying. Caged birds vocalized more. When tested individually, the aviary birds were more active in a novel test chamber and were more likely to approach an unfamiliar bird than were caged birds.
