Cockatiels are among the most popular pet birds worldwide, known for their gentle nature and charming crests. But many new bird owners often ask:
“Is a cockatiel a cockatoo?”
The answer is yes — but with important differences. In this article, we’ll explore the taxonomy, physical characteristics, behavior, and care differences between cockatiels and cockatoos. Backed by scientific data and avian veterinary insight, this guide aims to clarify the connection between these beloved parrots.
Taxonomy: Where Do Cockatiels Fit in the Parrot Family Tree?
| Classification Level | Cockatiel (Nymphicus hollandicus) | Other Cockatoos (e.g., Sulphur-Crested) |
|---|---|---|
| Kingdom | Animalia | Animalia |
| Class | Aves | Aves |
| Order | Psittaciformes | Psittaciformes |
| Family | Cacatuidae (Cockatoos) | Cacatuidae |
| Genus | Nymphicus | Cacatua, Calyptorhynchus, etc. |
Conclusion: Cockatiels are members of the Cockatoo family (Cacatuidae) — they are the smallest and only species in the genus Nymphicus.
Expert Insight:
“Think of cockatiels as the ‘mini-cockatoos’ — they share many traits but differ significantly in size, voice, and social needs.”
— Dr. Hannah Lewis, Avian Behaviorist
Key Similarities Between Cockatiels and Cockatoos
| Trait | Description |
|---|---|
| Crest Feathers | Both have expressive crests that reflect mood (alert, relaxed, agitated) |
| Zygodactyl Feet | Two toes forward, two backward – ideal for gripping and climbing |
| Powder Down Feathers | Produce a fine dust that protects feathers (can cause allergies) |
| Affectionate Nature | Both form strong bonds with humans and enjoy interaction |
| Lifespan | Longer than typical pet birds (Cockatiels: 15–25 yrs; Cockatoos: 40–80 yrs) |
Differences Between Cockatiels and Cockatoos
| Category | Cockatiel | Cockatoo |
|---|---|---|
| Size | 12–14 inches, 90–120 grams | 18–24+ inches, 350–1,000+ grams |
| Noise Level | Moderate, whistling and chirping | Loud, piercing screams, very vocal |
| Social Needs | Enjoys interaction, tolerates solitude | Needs intense daily socialization |
| Cost (Canada/US) | $150–$300 | $2,500–$15,000+ |
| Cage Size | Medium | Extra-large aviary required |

Veterinarian Perspective:
“Many owners adopt cockatoos thinking they behave like cockatiels. In reality, cockatoos need far more attention and can suffer emotional distress without it.”
— Dr. Clara Nguyen, DVM
