Round bird cages: why you should absolutely avoid them
The round cage should be ruled out for all birds: with no corner to retreat to, it disorients and unsettles them, its shape prevents horizontal flight and its narrowness makes any proper layout impossible. Several countries have even restricted its sale. A rectangular cage, wider than it is tall, is always the better choice, whatever the budget.
Why does the round shape stress birds?
A bird finds its bearings in space thanks to corners and retreats into one when worried. In a round cage there is no corner: the bird can never psychologically « settle ». The converging bars at the top also present a real risk of trapping a leg or toe. Add the 360° exposure with no sheltered zone, and you get an animal on permanent alert.
How does the round cage prevent flight?
Birds fly horizontally, from perch to perch. The round cage, tall and narrow, offers no flight path: the bird can only climb along the bars. Over time: muscle wastage, excess weight and boredom. A rectangular cage 80 cm long costs 60 to 100 €, often cheaper than a « decorative » brass round one. Our comparison cage or aviary helps you get the sizing right.
What other practical flaws should you know about?
- Impossible to furnish: perches and toys mount poorly on curved walls.
- Tedious cleaning: a circular base with no tray that fits standard liners.
- Badly placed feeders: often under the perches, hence soiled.
- Instability: many are hung up and swing at the slightest movement.
What if you already own a round cage?
Replace it as soon as possible with a rectangular model and demote the round one to a decorative role (plant, fairy lights). During the transition, place it against a wall, at eye level, with one side partially covered to create a refuge zone. If your bird shows entrenched stereotypies — endless loops of climbing along the bars, feather plucking —, an avian vet or a behaviourist can guide you. All our housing benchmarks are in the housing and habitat section and on the bird hub.
Frequently asked questions
Why are round cages still sold?
For their « retro » look: they appeal to the buyer, not to the bird. Treat them as decorative objects, never as a home.
Is a large round cage acceptable?
No: even a large one offers neither a reassuring corner nor a flight path. Volume for volume, the rectangular cage always wins.
What shape for a canary rather than a budgie?
The same: rectangular and longer than it is tall — the canary flies even more than it climbs.
