Species now placed in this genus were formerly assigned to the genus Accipiter. Molecular phylogenetic studies found that Accipiter was polyphyletic and in the subsequent rearrangement to create monophyletic genera, the genus Astur was resurrected in 2024 to contain nine species that were previously placed in Accipiter.[5][6][7]
