Hieraves is a clade of telluravian birds named by Wu et al. (2024) that includes the orders Strigiformes (owls) and Accipitriformes (hawks and their relatives).

[1] The Cathartidae (New World vultures) are usually included in Accipitriformes,[2] but some authors treat them as a third order Cathartiformes in the Hieraves.

[citation needed] In the past, either owls, New World vultures, and hawks were found to be basal outgroups with respect to Coraciimorphae inside Afroaves,[3][4] or Accipitriformes and Cathartiformes were recovered as a basal clade in respect to the rest of the members of Telluraves.

[6] The analysis of Wu et al. (2024) has found Hieraves to be the sister clade to Australaves.

[1] Stiller et al. (2024) found Hieraves to be basal to Afroaves.
