The full species status of the North American Northern Harrier Circus (cyaneus) hudsonius – once considered to be a subspecies of Hen Harrier C cyaneus – has received further support in a new DNA analysis of the whole of the genus.

Northern Harrier is actually sister species to the South American Cinereous Harrier C cinereus, and part of a separate lineage to Hen Harrier. African Marsh C ranivorus and Marsh Harriers C aeruginosus also emerged as sister species, while the separate specific status of Réunion C maillardi, Malagasy C macrosceles and Eastern Marsh Harriers C spilonotus has also been upheld.
