The Semi-collared Hawk is a bird of prey species of in the Accipitridae family. Usually named Accipiter collaris, it is the sister species of the Tiny Hawk ("A." superciliosus). The latter is the only species of the genus Accipiter yet studied which has a large procoracoid foramen. The collaris-superciliosus superspecies also differs from the typical sparrowhawks in other respects of its anatomy and as regards DNA sequence. Consequently, the old genus Hieraspiza may be more appropriate for them.
