RSPB worries about Hen Harriers in England

The RSPB worries about the future of Hen Harriers in England.
According to the RSPB there is habitat for about 300 pairs of Hen Harriers in the UK but only 12 pairs tried to nest there in 2010 and only 7 pairs were successful.
Widespread illegal persecution of the fully protected birds is the most serious threat for Hen Harriers in England.
