The Western Marsh Harrier has the habitual "flippy-floppy" flight of all Harriers, especially when hunting low over fields and marshes, though on occasion it can surprise one by being found high, especially on migration.
The male's grey wings with black wing-tips are striking, as are the female's ginger head and shoulders. There often appear to be many more female Marsh Harriers than males, but this is simply because a fair number of males sport female plumage in order to mate surreptitiously with an already paired female without running the risk of the official partner's aggression.
