IdentificationHen Harriers may glide slowly over the ground on V-shaped wings like Marsh Harriers but they are always smaller and slimmer. The male lacks the brown body of a Marsh Harrier and so looks almost completely grey, or even white, apart from the black wing tips and the smoky trailing edge to the wing. Females or immatures are slimmer and noticeably longer in the wing than Marsh Harriers and have obvious white rumps. Their barred tails earn them the nickname of 'ringtails'. HabitatBreeds on moorland and in young conifer plantations. Winters on moorland and on lowland fields, marshes and estuaries. BehaviourThe male has a spectacular tumbling and somersaulting display. This involves diving steeply towards the ground then rearing up almost vertically before shooting downwards again. This can be repeated several times in quick succession. MigrationEurope's northern and eastern populations are migratory, spending the winters in central and southern Europe. A few individuals have been recorded crossing the Mediterranean into north Africa and even the Middle East. This information is taken from the BirdFile on the appropriate BirdGuides DVD-ROM. As well as video and sounds, our CD- and DVD-ROMs contain additional text on Voice, Sexing, Ageing, Food, Nests and Eggs and more.
