Sun Conures are active, acrobatic birds that need considerably more space than their twelve-inch body length might suggest. The minimum recommended cage size for a single Sun Conure is 24 inches wide by 24 inches deep by 30 inches tall, but larger is always better. A flight cage measuring 36 by 24 by 36 inches or greater allows room for wing stretching, climbing, and short flights between perches, all of which contribute to physical and psychological health.
Bar spacing is a critical safety factor. For Sun Conures, bar spacing should be between half an inch and three-quarters of an inch. Spacing wider than three-quarters of an inch creates a risk of the bird squeezing its head through the bars, which can result in injury or escape. Horizontal bars on at least two sides of the cage are preferable because they allow the conure to climb, which is one of their primary forms of exercise.
Cage shape also matters. Rectangular or square cages provide more usable interior space than round or novelty-shaped enclosures. Round cages can cause psychological stress in some parrots because there are no corners where the bird can retreat and feel secure. The cage should be placed at chest height or slightly above in a room where the family spends time, as Sun Conures are highly social and become distressed when isolated.
Even with a generously sized cage, Sun Conures should receive several hours of supervised out-of-cage time each day. A dedicated play stand or bird-safe room provides space for flying, socializing, and exploring. The cage should be thought of as the bird's safe home base rather than its entire world.
