The dwarf sparrowhawk (Accipiter nanus), also known as the small sparrowhawk, is a species of bird of prey in the Accipitridae family. It is endemic to Indonesian islands of Sulawesi and Buton. Its natural habitats are subtropical or tropical moist montane forests and to a lesser degree lowland forests. It closely resembles the fellow Wallacean vinous-breasted sparrowhawk, but is still thought to be most closely related to besra. All this makes it rather difficult to identify and thus possibly under-recorded. It is one of the smallest members of its family (length approximately 25 cm/10in). Hunts insects and small birds.
