During a day spent at RSPB Titchwell on the north Norfolk coast in June the bird sightings were many and varied but one of the undoubted highlights for me was a marsh harrier which made regular appearances throughout the day.
The marsh harrier is one of our least numerous birds with around 400 females in the UK. According to the British trust for Ornithology it almost became extinct in the UK but has made a small recovery. It lives and breeds in reedbeds but during it’s recovery it has learnt to frequent farmland too. With the destruction of its normal habitat that adaptation may prove to be its saviour.
Marsh harriers hunt small mammals and birds and can be seen gliding over marshland and reedbeds with their wings in a characteristic shallow ‘V’ shape. It is restricted to East Anglia in the UK and its conservation status is Amber due to the declines seen in the past.
Despite its amber staus in the UK it is a species of least concern in the rest of Europe, which is good news. Hopefully a few more will find their way here to swell the UK population. They can mostly be seen here in nature reserves and the small number of locations where reedbeds and wetlands have not been drained.
One of the best reserves for harriers is Wicken Fen lying between Cambridge and Ely, and this is the only place where I’ve seen marsh harriers and hen harriers in the air at the same time. Wicken is owned by the National Trust and has a hundred year expansion plan which involves buying up the surrounding farmland as the soils becomes progressively downgraded and ultimately exhausted. So in around 100 years time it should be an enormous area of fen and home to large numbers of rare birds such as the harriers. So they may not be so rare then. Fingers crossed!
