These species of sparrowhawks have an extremely large range and population and are considered least vulnerable. Widespread persecution, use of harmful organochlorine pesticides, trapping by falconers, wind energy farms and habitat loss are the major threats for the survival of these species of birds.

The IUCN (International Union for Conservation of Nature) has categorized and evaluated these sparrowhawk species and has listed them as of "Least Concern".
