About the Montagu's Harrier

Montagu's harrier (Circus pygargus) is a species of harrier, a bird of prey in the family Accipitridae. It breeds in large open areas in the Palearctic and is migratory, wintering in Africa, the Indian subcontinent and parts of the Arabian Peninsula. Its common name commemorates the British naturalist George Montagu.

The first formal description of Montagu's harrier was by the Swedish naturalist Carl Linnaeus in 1758, in the tenth edition of his Systema Naturae, under the binomial name Falco pygargus. The genus Circus was introduced by the French naturalist Bernard Germain de Lacépède in 1799. The genus name is derived from Ancient Greek. Circus is from kirkos, meaning "circle", referring to a bird of prey named for its circling flight (probably the hen harrier), and pygargus is Modern Latin derived from the Greek pugargos, from puge, meaning "rump", and argos, meaning "shining white". The species name was formerly used for the hen harrier before Montagu's was identified as a different species.

Sexual dimorphism is particularly apparent in the plumage of this species. Adult males are characterized by their overall pale grey plumage... Wikipedia →
