Hen harrier in England (IN7.8)

Habitat requirements

In the past, hen harriers bred in many areas of Britain, and nests were sited in crop fields, marshes and heathland in the lowlands, as well as on the remote upland moorlands that provide the main breeding habitat today.

In parts of Europe, including northern France, hen harriers still breed successfully in arable crops although the nests often require human intervention to prevent the chicks being killed by machinery as the crop is harvested. In Britain, although both marsh harriers and Montaguís harriers breed successfully in fields of crops, the hen harrier is now restricted to moorland in the breeding season and occurs on lowland farmland only in winter.
