Timetree of extant Otidimorphae, with the distribution of each family being indicated by the colour-code used throughout this website (see Distribution code). The relationships are based on Jarvis et al. (2014) and Kuhl et al (2021), while Prum et al. (2015) considered Otididae and Cuculidae as sistergroups. The divergence time follow Kuhl et al. (2021).
