Ringtail Harrier at Carlton Marshes

On Saturday 31st January, I drove to Carlton Marshes, at the Tower Hide Ivan L joined us. At 3pm, Ivan was locking up so we had to vacate the hide, I walked along the path to Share Marsh. From the Octagon Platform, I saw 2 Marsh Harriers, I then saw a third bird it was the superb ringtail Hen Harrier was hunting low just this side of the Peto's Marsh bund and then it flew south along the field. Later on I saw it just south of Share Marsh.
