Seven in 10 hen harriers in UK study likely illegally killed

Bird of prey 10 times more likely to die on English grouse moors than other habitats

Hen harriers are 10 times more likely to die or disappear from or near to English grouse moors than any other habitat, according to a long-term study which reveals the scale of the illegal persecution of the endangered raptor.

An analysis of hen harriers over a decade found 72% of 58 satellite-tagged birds were confirmed or considered "very likely" to have been illegally killed. Just 17% of juvenile hen harriers survived beyond their first year around grouse moors in northern England and southern Scotland, compared with 36% across the Scottish mainland, where persecution has also been recorded, and between 37% and 54% on Orkney, where there are no grouse moors.
