Circus macrourus (Pallid Harrier)

Synonyms: Accipiter macrourus (homotypic)

Wikipedia Abstract

The pale or pallid harrier (Circus macrourus) is a migratory bird of prey of the harrier family. The scientific name is derived from the Ancient Greek. Circus is from kirkos, referring to a bird of prey named for its circling flight (kirkos, "circle"), probably the hen harrier and macrourus is "long-tailed", from makros, "long" and -ouros "-tailed". This medium-sized raptor breeds on open plains, bogs and heathland. In winter it is a bird of open country.
