The order Anseriformes (waterfowl) contains three families:

• Anatidae (ducks, geese, swans)
• Anseranatidae (Magpie-Goose)
• Anhimidae (screamers)

Family-level timetree of extant Anseriformes with the interfamilial relationhips being based on Prum et al. (2015). The distribution of each family is indicated by the colour-code used throughout this website (Distribution code). Divergence times follow Kuhl et al. (2021).
