Wing Tagging Marsh Harriers Circus Aeruginosus in Norfolk
Between 1990 and 2010 North West Norfolk Ringing Group had metal
ringed 213 Marsh Harrier nestlings only 7 were ever
all were found dead.
The wing tagging project began in 2011 and by the end of 2022 a total of 786 nestling Marsh Harriers had been ringed and wing tagged plus 5 adults. This has resulted in a recovery/sighting rate of 38.18% a result that could not have been anticipated.
Individuals that have been marked in this project have been
reported and photographed all
over the UK.
Many have involved multiple sightings of the same bird providing a
fascinating snapshot of their ‘life’ history so far. Many of these
birds that have been tagged in this project have been
in Belgium, Portugal, Germany, The Netherlands, Spain and Norway and the
first confirmed sighting of a British ringed Marsh Harrier in Senegal
and another in the Canary Isles.
Sightings of wing tagged birds should be
reported to the project co-ordinator
