RSPB press release (21/3/18):
RARE HEN HARRIER GOES MISSING IN WALES
North Wales Police and the RSPB are appealing for information following the disappearance of a satellite-tagged hen harrier near Wrexham.
The harrier, named Aalin, was tagged as part of the RSPB’s EU-funded Hen Harrier LIFE+ project in July 2016 from a nest on the Isle of Man, in collaboration with Manx Birdlife. Aalin left the Isle of Man in 2016 and spent her first winter in Shropshire, before heading to Wales in the spring of 2017, where she remained ever since.

Aalin’s tag had been transmitting regularly, until it suddenly stopped on the morning of 9 February 2018. Data from Aalin’s tag indicated she spent the last few months in the same area of moorland around Ruabon Mountain near Wrexham, from where the tag unexpectedly sent its last signal at 10.34am. A search was conducted by RSPB Investigations staff, but no tag or body was found and she has not been seen or heard of since.

Dr. Cathleen Thomas, RSPB Hen Harrier LIFE Project Manager, said: “It’s incredibly disappointing to lose yet another hen harrier in these circumstances, especially as this bird is so scarce in the UK. It’s also the first suspicious loss of a bird in Wales for our project, after the elation of tagging our first chicks there in 2017. We were hopeful that heading towards the breeding season Aalin would have nested in Wales and successfully reared chicks this summer, so her loss also affects future generations of this rare and beautiful bird in the area. We believe the loss of Aalin and other recently tagged hen harriers in the UK is having a devastating impact on their conservation status.”
Rob Taylor, Rural Crime Team Manager, North Wales Police, said: “We have been notified by the RSPB of this incident and we are investigating the disappearance, but at this time we have little to go on. We are appealing to the public for any assistance they can give and we hope that foul play hasn’t played a part in the loss of this rare bird.”
Neil Morris, Managing Director of Manx Birdlife, said: “This is heart-breaking news. As well as the sudden unexplained loss of yet another magnificent bird of prey, we still know so little about the behaviour of Manx-born hen harriers. Clearly there is an impulse for young birds to wander soon after fledging. But we don’t really know why or whether any of those that leave the Isle of Man as juveniles make the return journey as mature adults to breed back in their native hills.”

Dr Cathleen Thomas, RSPB’s Hen Harrier Life Project Manager has also written a blog – here.
We’ve produced a habitat map covering the area of Aalin’s last known satellite-tag fix. The tell-tale heather strips show this as, surprise surprise, a grouse moor:

Aalin was one of the 2016 cohort of young satellite-tagged hen harriers. Here’s what happened to the others:
Hen harrier Elwood – ‘disappeared’ in the Monadhliaths just a few weeks after fledging, presumed dead (Aug ’16).
Hen harrier Brian – ‘disappeared’ in the Cairngorms National Park just a few weeks after fledging, presumed dead (Aug ’16).
Hen harrier Donald – missing in northern France, presumed dead (Autumn ’16).
Hen harrier Hermione – found dead on Mull, believed to have died from natural causes (Sep ’16).
Hen harrier Rowan – found dead in Yorkshire Dales National Park. He’d been shot (Oct ’16).
Hen harrier Tarras – ‘disappeared’ in the Peak District National Park, presumed dead (Oct ’16).
Hen harrier Beater – ‘disappeared’ in the Scottish Borders, presumed dead (Nov ’16).
Hen harrier Bonny – ‘disappeared’ in the North Pennines, presumed dead (Dec ’16)
Hen harrier Mick – ‘disappeared’ in the Yorkshire Dales National Park, presumed dead (Dec ’16).
Hen harrier Carroll – found dead in Northumberland, PM revealed a parasitic disease & two shotgun pellets (Jan ’17).
Hen harrier John – ‘disappeared’ in the Yorkshire Dales National Park, presumed dead (Oct ’17)
Hen harrier Aalin – ‘disappeared’ in Wales, presumed dead (Feb ’18)
Twelve down, five to go (DeeCee, Finn, Harriet, Wendy, Sorrel).
More evidence then, that DEFRA’s Hen Harrier Action Plan, launched on 16 January 2016 months before these hen harriers even hatched, is a categorical failure. Will DEFRA or any of the other supporters of this pathetic pantomime (Natural England, Moorland Association, GWCT, Hawk & Owl Trust, International Centre for Birds of Prey etc) re-assess and pull the plug? Of course not.
