Missing sea eagle sparks wildlife crime investigation in raptor persecution hotspot

Six police officers pulled up to the Snilesworth estate in two pickup trucks on an ordinary day last week, climbed into the moors, and began searching for something that should have been impossible to lose. A white-tailed eagle—a bird with a wingspan of two and a half meters, the largest raptor in the UK, colloquially known as a flying barn door for its sheer ungainliness in the air—had vanished. The estate itself is a sprawling, undulating expanse on the western edge of the North York Moors, globally famous for grouse, partridge, and pheasant shooting, and locally famous for the helicopters and blacked-out SUVs that ferry wealthy Londoners to its grounds. But this time, the officers from the national wildlife crime unit and North Yorkshire police were not there about game birds. They were there about a mystery.

The bird in question was born last August on the Isle of Wight, part of an ambitious reintroduction effort that began in 2019. White-tailed eagles once ranged across the UK until human persecution drove them to extinction in England—the last breeding pair vanished in 1780. Since then, the Roy Dennis Wildlife Foundation and Forestry England have released 45 young birds back into the wild. Two of them bred in Dorset in 2025, an event that had not occurred in that county for 240 years. The missing eagle was their offspring, fitted with a satellite tag at birth, tracking its location and body temperature every five minutes. For the first three years of life, these birds are nomadic, restless with what one researcher called their "wanderlust." This one had ranged from the south coast to Scotland, to Loch Strathbeg in Aberdeenshire, back to Dorset, and then north again to the North York Moors in late April.

On April 30, the eagle entered the moors. At 1:20 a.m. on May 1, the tag recorded it alive at a roost site. Then the signal stopped. The tag, which transmits data every six hours, went silent and has remained so. Estate staff and the RSPB searched the area where the bird's last location was recorded. They found nothing. The tag itself is highly reliable—there is no technical reason for it to fail. The silence, investigators say, is suspicious.

North Yorkshire has earned a grim reputation among bird lovers. Between 2015 and 2024, 921 confirmed incidents of raptor persecution were recorded across the UK, and at least 55 percent occurred on or near land managed for game bird shooting. North Yorkshire alone accounts for nearly 22 percent of those incidents—more than any other county. In that period, 138 birds were killed there: buzzards topped the list, followed by red kites and hen harriers. Half were shot, a fifth poisoned, 13 percent trapped, and the rest subjected to nest destruction or other forms of persecution. These figures, according to the RSPB, represent only the visible fraction of a much larger problem. Many incidents go unseen and unreported.

Mark Thomas, head of investigations at the RSPB, runs a 15-person team that assists police with wildlife crime cases. He helped secure a conviction this January against a gamekeeper named Racster Dingwall and two others who were recorded in camouflage on Grassington Moor, using radios to coordinate the shooting of hen harriers. When asked about the missing eagle, Thomas was blunt: "This eagle has vanished in the worst county in the UK for bird crime. North Yorkshire is consistently the worst and has been for like decades." He noted that this was not the first bird from the reintroduction project to disappear—three others went missing last year in Wales, Scotland, and Sussex. Birds of prey are not killed for sport but to prevent perceived threats to game birds or livestock. "All of those cases have been concluded because they just can't prove what happened," Thomas said. Regarding the latest disappearance, he reasoned that something likely occurred in the middle of the night while the eagle roosted. "If you're asking me to look at the probability, it's most likely the bird has been shot. And if the bird is shot whilst it's roosting, then it's being shot at night, potentially with thermal imaging gear."

The investigation faces the same obstacle that has stalled previous cases: proof. Thomas said the best hope for justice lay in the perpetrator's inability to stay silent. "What tends to happen in this community is people chat," he said. "They will literally go down the pub and say something." Dr. Ruth Tingay, director of the campaigning group Wild Justice, called for stronger police resources and expanded investigative powers. "Wilful blindness is no longer an option," she said.

Gamekeeper organizations urged caution. The British Association for Shooting and Conservation condemned the illegal killing of birds of prey but noted that no one yet knows what happened to the eagle. The National Gamekeepers Organisation pointed out that white-tailed eagles have little documented impact on game birds and that there is no evidence a gamekeeper was involved. Andrew Gilruth, chief executive of the Moorland Association, warned against drawing conclusions before facts were established. "Tags can fail," he said. "Birds can also die naturally or fall ill." Snilesworth estate management declined to comment. Charlie Woof, the head gamekeeper, was preparing for a charity clay pigeon shoot when asked about the missing bird. He refused to discuss it, citing private property. Woof has his own history with wildlife law: in 2008, as a 23-year-old junior gamekeeper on the same estate, he pleaded guilty to illegally trapping birds of prey using live pigeons as bait and was fined £100.

The range of possible suspects is vast—local farmers, others connected to nearby grouse lands, and numerous others with motive and opportunity. But the silence of the satellite tag, the timing of its failure, and the location where it went dark all point toward a single, dark possibility: that somewhere on those moors, in the darkness before dawn, something happened to a bird that should have been impossible to lose.
