Cockatoos, known for their dramatic crests and affectionate personalities, vary significantly in size depending on the species. Whether you’re preparing to adopt one or just curious, understanding their full size—including body length, wingspan, and weight—is crucial for proper housing, nutrition, and handling.
In this guide, we break down cockatoo sizes by species, provide insight into cage requirements, and explain what **“big” really means when it comes to these intelligent birds.

Cage Size Recommendations by Cockatoo Size
| Cockatoo Type | Minimum Cage Size |
|---|---|
| Small (Goffin’s, Galah) | 36” W x 24” D x 36” H |
| Medium (Umbrella, Sulphur-crested) | 40” W x 30” D x 48” H |
| Large (Moluccan, Palm) | 48” W x 36” D x 60” H |
- Bar spacing: 3/4” to 1”
- Horizontal bars are preferred for climbing
- Play gyms and daily out-of-cage time are essential for all sizes
Why Size Matters
- Flight & Exercise: Larger birds need greater space to stretch wings and stay healthy.
- Mental Stimulation: Big cockatoos are intelligent and require diverse environments.
- Diet Adjustments: Size impacts caloric needs and pellet portioning.
Growth & Maturity Timeline
| Age | Size Stage |
|---|---|
| Hatchling | ~2–3 inches |
| 8 weeks | ~80–90% of full length |
| 1 year | Full physical size |
| 2–4 years | Sexual maturity reached |
Cockatoos reach their full size by 12 months, but behavioral and hormonal maturity may take longer, especially in larger species.
lnsight
“One of the most common mistakes new owners make is underestimating how large cockatoos really are—and how much space they need to thrive. A 20-inch bird with a 40-inch wingspan cannot be happy in a small cage, no matter how much love you give it.”
