How big should a bird cage be?

The most common mistake new bird owners make is buying a cage that is too small. A cage is not just a place to sleep — it is where your bird spends a significant part of its life, and size directly impacts physical and psychological health.

The universal minimum rule

The cage must be large enough for the bird to fully extend both wings simultaneously and flap without touching the sides. This is the absolute minimum — a good cage provides substantially more space than this.

Recommended minimum cage sizes by species

| Species | Minimum cage (L × W × H) | Bar spacing |
|---------|--------------------------|-------------|
| Budgerigar (budgie) | 60 × 40 × 40 cm | 1–1.2 cm |
| Cockatiel | 75 × 60 × 90 cm | 1.5–2 cm |
| Lovebird / Parrotlet | 60 × 60 × 60 cm | 1–1.5 cm |
| Conure (small) | 75 × 75 × 90 cm | 1.5–2 cm |
| African Grey / Amazon | 90 × 90 × 120 cm | 2.5 cm |
| Macaw (large) | 120 × 90 × 150 cm | 2.5–3.5 cm |
| Canary / Finch | 90 × 45 × 45 cm | 1 cm (no wire mesh) |

These are starting points — bigger is always better.

Bar orientation matters

Parrots naturally climb. Horizontal bars allow climbing; vertical-only cages are inferior for parrots. The best parrot cages have predominantly horizontal bars.

What to include in the cage

- Multiple perches of different diameters and textures (not just the plastic dowels that come with most cages — these cause foot problems). Natural wood branches, rope perches, and heated perches (for older birds) are excellent.
- Multiple feeding stations to reduce competition if multiple birds are housed together
- Water dish and bath option
- Minimum 3–4 toys, rotated weekly to prevent boredom
- At least one enclosed hiding spot

Cage placement

- At eye height or slightly below — being too high above humans can reinforce dominance behaviour in parrots
- Away from kitchen (cooking fumes and PTFE/Teflon are immediately fatal to birds)
- Away from draughts, air conditioning, and direct noon sun
- In a room where the family spends time — social isolation causes psychological damage
