RSPB press release (24 July 2025)
Chicks fledge with RSPB support after suspicious loss of parent Hen Harriers.
- In May 2025, over a period of eight days, four breeding male Hen Harriers suspiciously disappeared from their nests in northern England – two from RSPB Geltsdale Nature Reserve in Cumbria, and a further two from the Forest of Bowland in Lancashire.
- The disappearances point to yet more illegal killing, which is the main factor limiting the recovery of this rare, red-listed species in the UK.
- A quick response by reserve staff and volunteers has resulted in the successful fledging of five Hen Harrier chicks from two of these nests.
Against the odds, five healthy Hen Harrier chicks have now successfully fledged from two nests in Northern England, following the suspected illegal killing of the male parent birds. Two of the nests failed at incubation stage but RSPB staff and volunteers quickly responded to the nests that had youngsters, providing periods of emergency supplementary food, under licence, to the females in a determined effort to save their chicks. In addition to providing food, staff and volunteers ensured the nests were closely monitored.

Chris Hind, a volunteer at Geltsdale RSPB Reserve ‘’We were incredibly hopeful that our efforts would pay off, but nothing was guaranteed. To see these birds take to the sky after weeks of tough work is fantastic but, as with all Hen Harriers in the UK, these birds face an uncertain future.”
Sadly, the disappearance of the four males fits a pattern and since 2020 a total of eight breeding males have disappeared whilst foraging away from the Geltsdale reserve. In 2023 a satellite-tagged male, known as Dagda, was found shot dead on neighbouring moorland [Ed: see here for Channel 4 News report]. It is highly unusual for a male to naturally desert its nest, and the loss of a male usually has a devastating impact on their breeding success with the female abandoning their nest.
In Bowland, one of the disappearing birds was a satellite tagged individual known as Dynamo, his tag suddenly stopped transmitting with no sign of malfunction. The tag data showed that over the previous 10 days he had remained within six kilometres of the nest but often travelled off the RSPB monitored land to forage. The sudden and suspicious disappearance of satellite tagged Hen Harriers are synonymous with suspected and confirmed incidents of illegal persecution. If birds die naturally, satellite tags still transmit data and are recoverable. Despite a land search at the last point of transmission no body or tag was recovered. Dynamo is the 115th satellite tagged Hen Harrier to have suddenly disappeared in the UK since 2010.
Lancashire and Cumbria Police launched investigations, however, to date no charges have been brought.
A recent RSPB report (Hen Harriers in the firing line) revealed that between 2020 and 2024, 102 confirmed and suspected incidents of Hen Harrier persecution were recorded in the UK, with most of these incidents taking place on or near land managed for grouse shooting. 89% of these incidents were recorded in Northern England.
To effectively prevent these crimes the RSPB is calling for greater regulation of the grouse shooting in England through the introduction of a robust licensing system. Only through this balanced and proportionate approach can a meaningful deterrent to those committing these crimes be introduced. This legislation was introduced in Scotland in 2024, under the Wildlife Management and Muirburn (Scotland) Act, whereby estates which are suspected of killing birds of prey may lose their licence to shoot grouse. This legislation has been well received by many within the industry in Scotland, as this legislation only penalises those who deliberately commit these crimes.
Mark Thomas, RSPB Head of Investigations UK: “Sadly, these four missing Hen Harriers are just the latest in a long line of identical incidents recorded over decades and demonstrates the catastrophic knock-on effect to the breeding success and recovery of this species.
‘Those killing Hen Harriers to do so with little or no fear of recrimination. Now is the time for the Westminster government to act on licensing this industry, if it is truly serious about the conservation of this amazing species.’

There’s so much to unpack in this press release. I’ll need to write a number of follow-up blogs to address the issues, that will include:
- Why Cumbria Police didn’t issue a press release or an appeal for information following the disappearance of the two adult males from Geltsdale (the RSPB told us about them in May – here);
- Why Lancashire Police didn’t issue a press release or an appeal for information following the disappearance of the two adult males from Bowland;
- Why the landowner, United Utilities, didn’t issue a press release or an appeal for information following the disappearance of the two adult males from Bowland;
- Why the Hen Harrier Taskforce didn’t issue a statement about these four missing Hen Harriers;
- Why a number of other police forces haven’t issued a press release or an appeal for information, and the HH Taskforce hasn’t issued a statement, about any of the other recently (i.e. in last few months) confirmed persecuted and ‘missing’ Hen Harriers that are still to be reported publicly;
- Why Defra Minister Daniel Zeichner didn’t mention any of these four ‘missing’ Hen Harriers (or any of the others known to have been killed and/or known to have ‘disappeared’ in suspicious circumstances in the last few months), when he was giving the government’s response on 30 June at the Westminster Hall debate on Wild Justice’s petition calling for a ban on driven grouse shooting.
I’ll come back to these issues, and more, shortly…
Meanwhile, well done to the RSPB staff and volunteers who have worked tirelessly to enable these Hen Harriers to fledge, and well done to the RSPB for telling the world about the suspicious disappearances of the four adult males.
UPDATE 24 July 2025: 143 Hen Harriers confirmed ‘missing’ or illegally killed in UK since 2018, most of them on or close to grouse moors (here).
