Details
Most harriers are placed in the genus Circus. This scientific name comes from the circling movements the birds make when courting.
Two other harriers are in the genus Polyboroides, the harrier-hawks, which are allopatric (geographically separated) and restricted to the Afrotropic ecozone. The remaining single species forms the genus Geranospiza.
Ring-tails
Ring-tail is an informal term used by birders for the juveniles and females of several harrier species. If seen in the field the exact species usually cannot be known. Ring-tail harriers include the juveniles and females of Montagu's harrier (Circus pygargus); Northern or hen harrier (Circus cyaneus); and pallid harrier (Circus macrourus).
