The Cuculiformes are represented by a single family, the Cuculidae (cuckoos). The phylogeny is not well founded, and the divergence times are still obscure:

the distribution of each taxon being indicated by the colour-code used throughout this website
(see Distribution code). Subfamily interrelations are based on Sorenson & Payne (2005), Prum et al. (2015), and Wang
et al. (2016).
