Have you seen a marsh harrier with an obvious bright green wing tag? Help researchers from the North West Norfolk Ringing Group (NWNRG) and the Hawk and Owl Trust track these birds’ movements by reporting your sighting to us so it can be added to the research project.

Marsh Harriers hatched in North Norfolk have been fitted with a lime green wing tag on each wing, bearing a unique identification code of two characters.
