The semicollared hawk (Accipiter collaris) is a bird of prey species of in the family Accipitridae. It is found in Colombia, Ecuador, Peru, and Venezuela. Its natural habitat is subtropical or tropical moist montane forests. It is becoming rare due to habitat loss.
Usually placed in the genus Accipiter, it is the sister species of the tiny hawk ("A." superciliosus). The latter is the only species in 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.
