RSPB press release:
ANOTHER RARE HEN HARRIER GOES MISSING
Police and the RSPB are appealing for information following the disappearance of a satellite-tagged hen harrier near Carlisle.
The harrier, named Manu, was one of a nest of two chicks monitored and protected by the Northumberland Hen Harrier Protection Partnership and tagged as part of the RSPB’s EU-funded Hen Harrier LIFE+ project in July this year.

Manu’s tag had been functioning perfectly until it suddenly stopped on the morning of 18 October 2017. Data from Manu’s tag indicated he had been in the same location near Denton Fell, on the Cumbria/Northumberland border, for around three weeks. The last signal was sent from Blenkinsopp Common at 0958hrs and he has not been seen or heard of since.
A search was conducted by RSPB Investigations staff but no tag or body was found. Northumbria Police were informed and have made enquiries but with no leads forthcoming.
Hen harriers are one of the UK’s rarest raptors with only three successful nests recorded in England in 2017.
Tim Jones, RSPB Assistant Investigations Officer said: “Hen harriers are facing an uncertain future: these spectacular birds should be flourishing in places like Cumbria and Northumberland but we are down to just a handful of pairs. So it’s alarming when yet another bird unaccountably vanishes like this.”
Andrew Miller, Head of Programmes and Conservation at Northumberland National Park, and Chair of the Northumberland Hen Harrier Protection Partnership, said: “With so few hen harriers breeding in England the loss of even a single bird is devastating. The Northumberland Hen Harrier Protection Partnership, along with many other organisations and individuals across the UK, is putting considerable effort into helping this struggling species recover.”
Don Churchill, Wildlife Co-ordinator & Planning Officer, Northumbria Police, said: “We are very concerned at the disappearance of one of these iconic birds of prey. Hen harriers are fully protected by law and raptor persecution is a national wildlife crime priority. We urge you to come forward if you have any information about the disappearance of this bird.”
If you have any information relating to this incident, call Northumbria Police on 101 or contact them via their website HERE. All calls are anonymous.
If you find a wild bird which you suspect has been illegally killed, contact RSPB investigations on 01767 680551 or fill in the online form.
ENDS
Here is a map we’ve created showing the position of Manu’s last known position (as identified from his satellite tag). This location is just outside two protected areas: Northumberland National Park and the North Pennines Area of Outstanding Natural Beauty (AONB).

This general area is a well known raptor persecution hotspot, which isn’t a surprise given how much of it is intensively managed for driven grouse shooting. Last December hen harrier Bonny ‘disappeared’ on a grouse moor just a few miles south of Blenkinsopp Common (Manu’s last known location), near to the RSPB’s Geltsdale Reserve from where Bonny had fledged.
Over the years, there have been five confirmed hen harrier shootings in this area (the killing of one of these was witnessed by RSPB investigators – see pages 38-40 in Mark Avery’s book Inglorious for a detailed description), there have been at least four attempted shootings of hen harriers, and another hen harrier was found poisoned. In addition, there have been poisoned ravens, poisoned buzzards and some shot peregrines.
Some of these crimes happened on the RSPB Geltsdale Reserve (safe to assume this wasn’t the handiwork of the RSPB wardens) and some of the crimes happened on nearby grouse moors.

We don’t know what’s happened to both Bonny or Manu, and if each case is taken in isolation it might be reasonable to conclude a failed satellite tag. These satellite tags are not perfect and do sometimes fail (e.g. see here), although overall they have a very high 94% reliability rate (see here). So it might just be possible that Bonny and Manu’s tags have suffered a technical malfunction, within that expected 6% failure rate, and that’s the story we’ll be hearing from the grouse-shooting industry over the coming days as they try to suppress any notion of criminal activity. However, what the criminal apologists will fail to mention is that when a tag suffers a ‘natural’ technical malfunction, there is typically a very clear indication several days prior to failure, from the tag’s engineering data, that a technical malfunction is imminent. What we’re seeing from the majority of these ‘missing’ sat tagged hen harriers (and golden eagles) is an abrupt, unexpected failure, often mid-way through a transmission cycle, which points to highly suspicious circumstances.
When you consider the disappearance of Bonny and Manu alongside all the other satellite-tagged hen harriers that have ‘disappeared’ without trace, many of them on or close to driven grouse moors, (at least 45 missing hen harriers since sat tagging began in 2007), and the fact that hen harriers haven’t bred on any English grouse moors for a number of years, then the picture becomes sinisterly clear. Add in the number of missing satellite-tagged golden eagles that have disappeared on or close to driven grouse moors in Scotland (41 of 131 tagged eagles) and the evidence of illegal persecution becomes compelling.
It’s no wonder the grouse-shooting industry objects so strongly to the satellite-tagging of raptors, and wants to control the public release of the data these tags are producing. The shooting industry can see what everybody else can see – they might be better at hiding the corpses these days but there’s absolutely nothing they can do to hide the results of the satellite tag data.
Well done to Northumbria Police and the RSPB for putting out a detailed press release, and especially for including the details of Manu’s last known location. We saw this happen two days ago when North Yorkshire Police revealed the last known location of hen harrier John, another satellite tagged harrier that has gone ‘missing’ on a grouse moor, this time in the Yorkshire Dales National Park.
If you haven’t already done so, please consider signing this NEW e-petition calling for a ban on driven grouse shooting. The Westminster Government continues to turn a blind eye to this carnage and continued public pressure is required to show them that we’re on to them and we’re not going away until they take appropriate action.
