Bermuda

Certain animals keep disappearing under suspicious circumstances in the UK’s ‘Bermuda Triangle’

A moorland in North Wales has earned the grim nickname “Wales’ Bermuda Triangle” after gaining notoriety for a string of mysterious bird disappearances. Ruabon Moor, located to the west of Wrexham, is regarded as one of the most notorious bird of prey persecution hotspots in the UK, according to the RSPB.

In late August 2025, a satellite-tagged female Hen Harrier vanished without trace on the moor. Data from late August revealed that the young bird had departed the Peak District National Park, coming to rest on Ruabon Moor on August 28.

By the night of August 31, satellite tag data confirmed that the bird was no longer alive.

A search was subsequently carried out and the tag was recovered, but the bird’s body was nowhere to be found. North Wales Police sent the tag away for forensic examination.

Results confirmed that the satellite tag’s harness had been deliberately severed using a sharp instrument, such as a knife. Despite extensive searches, the body has never been recovered.

The Hen Harrier is a rare and vulnerable, red-listed species in Wales and across the UK, with its recovery being directly undermined by illegal persecution.

Mark Thomas, RSPB’s UK Head of Investigations, said: “Sadly, this incident is a textbook example of Hen Harrier persecution and really shows the massive impact these crimes are having on this species. In this case a healthy young bird fledged from a safe area in the Peak District National Park and sadly chose to settle in ‘Wales’ Bermuda Triangle’ – the most notorious bird of prey persecution hotspot in the country.

“This three-month-old bird survived for just three days in the area before it vanished in highly suspicious circumstances. Based on years of evidence and intelligence, we suspect the criminal shot the harrier, cut the harness off the Hen Harrier’s body, discarded the tag and disposed of the body.”

Craig Best, General Manager for the National Trust in the Peak District, said: “We are devastated to learn of the fate of this magnificent bird that started its life on moorland in our care in the Peak District. Hen Harriers are an important species in the ecosystem of moorland habitats.

“We work hard to make sure these birds have good nesting and feeding grounds. Funding from our supporters helps us to restore the landscapes they need to give them the best chance of survival. If persecution is allowed to continue, we stand to lose a very important species that is crucial to the health of these landscapes and it can’t continue.”

Sgt Peter Evans, of North Wales Police Rural Crime Team, said: “In September 2025, North Wales Police received a report concerning the disappearance of a Hen Harrier on Ruabon Moor. Working in partnership with the RSPB and the National Wildlife Crime Unit, the harness was recovered and the investigation to date is inconclusive. Despite this, we can confirm that the harness had been intentionally severed, and the circumstances surrounding the bird’s disappearance are being treated as suspicious.

“Hen Harriers are a rare and protected species in Wales, making incidents of this nature particularly concerning. We urge members of the public to remain vigilant. If you witness any suspicious activity involving birds of prey, please report it to North Wales Police or the RSPB.”
