A genus of large black cockatoos native to Australia, known for their distinctive call and intelligence.
From Greek kalyptein (to cover) plus rhynchos (snout or beak), literally meaning 'covered beak,' referring to a special feathering characteristic of these birds. Scientific name established in the 19th century.
The Red-tailed Black Cockatoo (Calyptorhynchus banksii) can live 50+ years and mates for life, and they're so intelligent they can solve multi-step puzzles—yet they're listed as vulnerable due to habitat loss in Australia!
Complete word intelligence in one call. Free tier — 50 lookups/day.
