Family-level timetree of extant Coraciimorphae following Kuhl et al. (2021), with the distribution of each family being indicated by the colour-code used throughout this website (see Distribution code). Note, however, that Kuhl et al. (2021) did not include the genus Bucorvus (Bucorvidae), often considered a member of Bucerotidae, in their study.
