This order, the parrots, comprises the following families: 

  • Psittacidae (African and American Parrots)
  • Psittrichasidae (Vasa Parrots and Pesquet's Parrot)
  • Psittaculidae (Old World Parrots)
  • Cacatuidae (Cockatoos)
  • Strigopidae (New Zealand Parrots) 

Genus-level timetree of extant Psittaciformes, with the distribution of each genus being indicated by the colour-code used throughout this website (see Distribution code). The phylogeny is based on Provost et al. (2018), while the dating is based on the combined results of Rheindt et al. (2014), Schweizer et al. (2011, 2013, 2015),  White et al. (2011), and Kuhl et al. (2021).
