The Cuculiformes are represented by the Cuculidae (cuckoos). The phylogeny is not particularly well founded, and the divergence times are still mostly obscure:
Provisional genus-level phylogeny of extant Cuculidae following Nordén et al. (2023), with the distribution of each taxon being indicated by the colour-code used throughout this website (Distribution code). Available divergence times (Crotophaga + Geococcyx) + (Centropus + (Cuculus + Ceuthmochares + Piaya))) follow Stiller et al. (2024). [Chronotaxonomics would elevate current subfamilies to families. Cuculinae might have to be split into 2-3 families.]
Genus-level classification of extant Cuculidae.
