A rare bird of prey that breeds in Norfolk has gone missing in mysterious circumstances.
Sally, a Montagu's harrier, is fitted with a satellite tag. However, this stopped transmitting a signal on Sunday 6 August.
The RSPB says this is unusual because satellite tags are highly reliable and will continue transmitting signals even when a bird is dead.
Sally is paired with another Montagu's harrier called Roger. They are the only pair of Montagu’s harriers left in eastern England and one of only four pairs in the UK.
Sally and Roger have successfully bred in Norfolk for the past two seasons. This year they raised three juveniles.
