The key marks

Flies low over reeds with wings held in a shallow V; the male has grey wings with black tips and a brown body, the female is dark brown with a creamy head. Hen Harrier male is pale grey; the female has a white rump.

Voice

Mostly silent; a high 'kee-a' in display.

Good to know

In the courtship display, the male drops food in the air and the female catches it upside down below him.

Do not confuse with

Compare it with the Hen Harrier. Look at the marks above one by one rather than the overall colour, and practise telling the two apart with real photos.

Where and when

You can expect to find it in reedbeds, marshes and nearby farmland. Distribution changes with the seasons and from year to year, so check a recent local observation source before you go looking.
