CACATUIDAE

Cacatuoidea has its highest diversity in Australia, but it also occurs in New Guinea, Indonesia, Solomon Islands, and the Philippines. The phylogenomic time-calibrated tree shows Cacatuoidea splitting from Psittacoidea 35.9 Mya and that the clade has a crown age of 26.4 Mya (fig. 2). Our phylogeny further supports four subfamilies, in addition to the three now conventional: (1) Calyptorhynchinae—the large black-cockatoos with distinctively colored tail panels; (2) Nymphicinae—the small-bodied, monotypic Nymphicus hollandicus ; (3)
