The scientific family name for cockatoos, a group of large parrots with distinctive head crests.
From Malay kakak tua (old sister) + Latin -idae (family suffix). Scientific nomenclature combined the common Malay name with Latin taxonomy conventions.
Cockatoos are so distinctive that scientists gave them their own family—they're more distantly related to other parrots than many species are, making the 'old sister' birds a unique branch of parrot evolution.
