The cladogram of the Telluraves shown below is based on the study by Josefin Stiller and collaborators published in 2024. The species numbers are taken from the December 2023 version of the list maintained by Frank Gill, Pamela C. Rasmussen and David Donsker on behalf of the International Ornithological Committee (IOC). This list includes the Cathartiformes (New World vultures) in the order Accipitriformes.

Fossil record

The fossil record of Falconiformes sensu stricto is poorly documented. The only stem-falcons that have mostly complete remains are Masillaraptor parvunguis and Danielsraptor phorusrhacoides, while the other taxa Stintonornis mitchelli and Parvulivenator watteli are known from fragmentary remains. Mayr (2009) noted the similarity of Masillaraptor to the seriemas. One study from Wang et al. (2012) using 30 nuclear loci from 28 taxa found Falconidae and Cariamidae being sister taxa to each other. This has, however, not been supported by the latest major neoavian phylogenetic studies. A 2022 study recovers masillaraptorids as true falcons.
