Press release from RSPB (16th March 2023)
MISSING HEN HARRIER HAD SATELLITE TAG CUT OFF
*Anu, a satellite tagged Hen Harrier, vanished after roosting near Upper Midhope in the Peak District National Park – on land managed for driven grouse shooting.
*RSPB Investigations Officers located the bird’s tag three days later and police forensics found it had been deliberately cut off the bird. Investigators fear the bird was illegally killed and his tag removed to hide the evidence.
*Anu joins a long list of birds of prey which have suspiciously disappeared or been killed in relation to land managed for driven grouse shooting. Licensing of grouse shooting as a meaningful deterrent to wildlife crime is needed in England, replicating current proposals in Scotland.
Yet another mysterious disappearance involving a rare Hen Harrier has been identified by the RSPB and South Yorkshire Police.
Anu, a young male, tagged in Bowland in 2021, was one of several young Hen Harriers fitted with a satellite tag by the RSPB: a small, unobtrusive device which enables scientists to monitor the movements of individual birds and gain greater understanding of this rare and criminally persecuted species.
Anu’s tag indicated that he was roosting on a grouse moor near Upper Midhope on 10 February 2022. However, the tag data showed unusual movement from the bird after 10.25pm that night, when Anu would normally have been stationary.
The tag’s next signal on 11 February was more surprising still, indicating the bird was dead. After an intensive search, the tag was found, some 9km away to the east, on 14 February at Wharncliffe Chase. But suspiciously there was no sign of the body.
This was reported to South Yorkshire Police and forensic analysis confirmed the tag harness had been cut by a human rather than bitten or pulled off. The RSPB suspects that Anu was killed, and the body and tag separated to remove evidence from the crime scene, with the tag then dumped. Anu’s body remains missing, and further enquiries have been unsuccessful.
Tom Grose, RSPB Investigations Officer, said: “To find Anu’s tag detached from his body, having been deliberately cut off, categorically shows human involvement. It is highly suspicious that he roosted on a grouse moor the night before, was unexpectedly active in the hours of darkness and hasn’t been seen since.
“We suspect that Anu was killed that night, his tag cut off and then the body dumped away from the grouse moor by someone trying to cover their tracks. The deliberate killing of a wild bird is illegal, yet sadly criminal persecution has been identified is the main reason driving Hen Harrier declines.”
A 2019 study of satellite-tagged Hen Harriers by Natural England revealed that 72% of 58 satellite-tagged Hen Harriers were either confirmed or considered very likely to have been illegally killed. Furthermore, it found that Hen Harriers were ten times more likely to vanish mysteriously or die on a grouse moor than anywhere else.
Tom added: “When only a small percentage of Hen Harriers in the UK are tagged, you can’t help wonder what is happening to the other non-tagged birds. This is a species in trouble, and the UK population remains far below what it should be. As the nature crisis tightens its grip, illegal persecution of raptors must be stopped and that will only happen through the licensing of driven grouse moors – as is happening in Scotland – to bring accountability to this form of land management.”
The RSPB would like to thank South Yorkshire Police and the National Wildlife Crime Unit (NWCU) for their work on this case.
If you have any information about this incident, or know of anyone killing birds of prey, please call South Yorkshire Police on 101. The RSPB also has a dedicated confidential Raptor Hotline: 0300 999 0101. This is for information relating to crimes involving birds of prey only.
ENDS
The news of this latest ‘missing’ hen harrier coincides with the publication of some (more) propaganda from Natural England yesterday about how they’re planning to extend their dodgy hen harrier brood meddling trial. I’ll comment on that over the weekend, because that coincides with a recent FoI response I received about NE’s plans for brood meddling, but I won’t have time to write it before the weekend.
Meanwhile, I’ll just update the VERY long list of hen harriers that have been confirmed illegally killed or that have ‘disappeared’ in suspicious circumstances, mostly on or close to grouse moors, since the start of NE’s hen harrier brood meddling trial in 2018. We’re up to 77 and counting… I don’t see Natural England promoting those awkward but damning data.
Anu was already on the list of 77 – his suspicious disappearance was reported in February 2022 (here).
