Last Friday afternoon, Natural England quietly published its latest sporadic update on the status of its satellite-tagged hen harriers. This is essentially an excel spreadsheet that provides the public with little more than the bare minimum of data about tagged individuals.
The latest update was done without fanfare; indeed NE appears to have said absolutely nothing at all about it. I’m not surprised, given what the data show. NE was probably hoping that nobody would notice but that’s a gross underestimation of the level of public interest in this species, and the illegal persecution of it, on many driven grouse moors across the UK.

It won’t come as a surprise to any regular reader of this blog that Natural England’s April 2025 update reveals that four more satellite-tagged hen harriers have ‘vanished’ since the start of this year.
That’s four more in addition to the one we already knew about this year – a young female hen harrier called ‘Red’, named by local schoolchildren. Red had hatched on the Tarras Valley Nature Reserve at Langholm in 2024 and was being tracked by the RSPB until she ‘disappeared’ in suspicious circumstances in Janaury 2025, on a grouse moor in Co Durham, from where another tagged hen harrier had also previously vanished a few years earlier in 2022 (see here).
Here are the details of the latest four to ‘disappear this year’:
- Female hen harrier named ‘Dina’, Tag ID 254837. Date of last contact: 12 January 2025 at grid reference NT 681512, near a grouse moor in the Lammemuirs, south Scotland.
- Female hen harrier, brood meddled in 2022 (R3-F2-22), Tag ID 213924. Date of last contact: 3 February 2025 at grid reference SE 759996, a grouse moor in the North York Moors National Park.
- Female hen harrier named ‘Bonnie’, Tag ID 254841. Date of last contact: 4 April 2025 in Scotland. ‘Site confidential – ongoing investigation’.
- Female hen harrier named ‘Gill’, Tag ID 240294. Date of last contact: 10 April 2025 in Scotland. ‘Site confidential – ongoing investigation’.
I haven’t seen any publicity about these four disappearances – no press releases, no appeals for information, just silence.
I’ll shortly be adding these four to my rolling list of dead/missing hen harriers.
In addition to these four ‘missing’ birds, a hen harrier has been found dead in the Yorkshire Dales National Park this spring and is listed as ‘awaiting post mortem’. This is another female, brood meddled in 2022 (R1-F4-22), Tag ID 232636. The date of last contact was 2 April 2025.
This death may or may not be suspicious/confirmed persecution – we’ll have to wait for the results of the post mortem. But don’t anyone hold your breath – there are six other hen harriers, found dead in 2024, and yet are still listed on Natural England’s spreadsheet as ‘awaiting post mortem’. One of them, ‘Susie’, was found over a year ago. Those six are:
- Female hen harrier named ‘Susie’, Tag ID: 201122. Last known transmission 12 February 2024, Northumberland. Found dead. Site confidential. In NE’s April 2024 update, Susie was listed as, ‘recovered, awaiting post mortem‘. Now her listing says, ‘Ongoing police investigation, final transmission location temporarily withheld at police request‘. You might remember ‘Susie’ – she’s the hen harrier whose chicks were brutally stamped on and crushed to death in their nest on a grouse moor in Whernside in the Yorkshire Dales National Park, in June 2022 (here).
- Female hen harrier named ‘Edna’, Tag ID: 161143a. Last known transmission 7 June 2024, Northumberland. Listed by NE as ‘Recovered, awaiting post mortem‘.
- Female hen harrier, Tag ID: 254843. Last known transmission 29 July 2024, Northumberland. Listed by NE as ‘Recovered, awaiting post mortem‘.
- Male hen harrier, Tag ID: 254839. Last known transmission 5 August 2024, Northumberland. Listed by NE as ‘Recovered, awaiting post mortem‘.
- Male hen harrier named ‘Chance’, Tag ID: 254840, last known transmission date 8 August 2024 in Cumbria. Listed by NE as ‘Recovered awaiting PM‘.
- Female hen harrier named ‘Sofia’, Tag ID: 34346, last known transmission date 3 October 2024 in Northumberland. Listed by NE as ‘Recovered awaiting PM‘.
Again, I haven’t seen any publicity about any of these deaths – no press releases, no appeals for information. Why is that? How come the RSPB can put out timely press releases/appeals for information about the hen harriers they’re tracking but Natural England can’t/won’t?
Surely the post mortems on these birds would have been completed months ago? And if they showed the birds had died of natural causes then surely the NE spreadsheet would have been updated to indicate this by now? The fact they are all still showing as ‘recovered awaiting PM’, months and in once case, over a year later, suggests to me that either NE needs new admin staff or that those hen harriers were illegally killed and NE and/or the police are withholding this information. It would be understandable if this was for operational purposes and in the case of the dead hen harrier found earlier this month, then ‘awaiting post mortem’ is obviously reasonable. But I find it very hard to believe that investigations into wildlife crimes that happened between six and 14 months ago are going to be jeopardised by telling the public that an offence was committed and an investigation is underway.
There’ll (hopefully) be a debate in Westminster Hall later this year following Wild Justice’s petition passing the 100,000 signature threshold. It would be helpful if up to date persecution figures were available to inform that debate.
