Predator or prey? The confounding case of the missing sea eagle | Birds

According to one account, six police officers arrived at the Snilesworth mansion in two pickup trucks last week. They wanted to go out to the steppes and “so they went,” one source said.

Snilesworth, a vast area of ​​spectacular rolling land at the western edge of the North York Moors, is world famous for its grouse, partridge and pheasant shooting. He is known locally for attracting “rich people from London in helicopters and blacked-out SUVs”.

But this time it was another rare flying visitor that caught the attention of the police: the North York Moors are at the center of a mystery about a missing bird of prey.

Officers representing the national wildlife crime unit and North Yorkshire police were searching for clues to the whereabouts of the white-tailed eagle, also known as the sea eagle and colloquially nicknamed the ‘flying barn door’ for its 2.5 meter wingspan, which makes them the UK’s largest bird of prey.

Little appears to have been found in the grove, which is said to have been the focus of police attention. But it appears they were concerned enough about the circumstances surrounding the bird’s disappearance that North Yorkshire police issued an appeal for information from the public on Monday.

“The eagle’s disappearance is considered suspicious and the investigation is ongoing,” the press release said.

This was a bigger issue than the average disappearance of birds. Since 2019, Roy Dennis Wildlife Foundation (RDWF) and Forestry England are looking at ways to reintroduce white-tailed eagles to the south coast.

Human persecution, once widespread in the United Kingdom, caused their extinction in England, with the last pair breeding there in 1780.

To date, 45 young white-tailed eagles have been released from the project’s base on the Isle of Wight. In 2025, two birds mated in Dorset; It was something not seen in this region for 240 years.

The resulting chick, which had been satellite tagged since birth and is now fully grown, has now disappeared. The reason for the disappearance is unknown. But one possibility, the RSPB says, overlaps with a largely undisputed scandal: the routine shooting, trapping or poisoning of birds of prey in the UK.

The proximity of the eagle’s last known location to a number of major grouse hunting grounds has not gone unnoticed. Between 2015 and 2024, 921 confirmed cases of bird of prey persecution were recorded; at least 55% of these occurred on or near land managed for game bird shooting. According to RSPB.

It is said that the figures represent only the tip of the iceberg, as many similar incidents go unseen and unreported.

Then it would be better to be careful. When the missing eagle was born last August, a satellite tag was strapped to its back. “It’s like a backpack,” said RDWF’s Tim Mackrill. White-tailed eagles are fairly nomadic for the first three years of their lives, and this year was no different.

“They have a wanderlust,” Mackrill said. “Last winter it was mostly on the south coast but this spring it has made a big flight to the east of England, Scotland and Lake Strathbeg in Aberdeenshire.

“It came up the south coast of Dorset, then went north again to the North York Moors in late April.”

Perhaps this was a fateful journey. North Yorkshire has a reputation among bird lovers as a bird of prey graveyard.

A fifth (21.84%) of confirmed persecution cases between 2015 and 2024 occurred in North Yorkshire; Among the 138 birds killed, vultures ranked first, followed by red kites and chicken hawks.

Of these, 50 percent were shot, 21 percent were poisoned, and 13 percent were trapped. The remaining 16% were subjected to other forms of cruelty, including the destruction of nests.

Mackrill said the signs are concerning. The tag on the missing eagle’s back recorded its location and body temperature every five minutes and sent data packets every six hours.

The bird entered the North York Moors at some point on 30 April. Mackrill said he was near a roosting area and was still alive at 1.20am the next morning when last signal was received.

“Then it went offline and we’ve had nothing since,” he added. “[Officers] I went to see the last known location but nothing was found. It is doubtful that the labels are truly reliable. “There is no reason for it to stop transmitting.” After the signal went out site staff assisted the RSPB in searching the area and nothing was found.

Mark Thomas, the RSPB’s head of investigations, leads a 15-strong team helping police investigate alleged wildlife crimes. This January he helped secure the conviction of gamekeeper Racster Dingwall and two others who were recorded wearing camouflage at Grassington Moor in the Yorkshire Dales by co-ordinating a plan to shoot chickens using walkie-talkies.

“This eagle has disappeared from the worst borough for bird crime in the UK,” Thomas said. “North Yorkshire is consistently the worst and has been for decades.”

He added that this was not the first time that birds involved in the white-tailed eagle reintroduction project had gone missing, with three birds missing in Wales, Scotland and Sussex last year.

Birds of prey are generally killed not for sport but to prevent any perceived threat to game birds or livestock. “All of these cases were settled because they couldn’t prove what happened,” he said. Regarding the latest disappearance, he mused: “I think something happened in the middle of the night while this eagle was perched. These things don’t fly in the dark anymore. They’ll wait until the light of day.”

“If you’re asking me to look at the probability… the bird was most likely shot. And if the bird was shot while roosting, then it was probably shot at night with thermal imaging equipment.”

Thomas added that the best hope for justice is if the perpetrator can’t stop himself from bragging. “In this community, what usually happens is people chatting,” he said. “They will actually go down to the bar and say something.”

Dr Ruth Tingay, environmentalist and director of the campaign group Wild Justice“Willful blindness is no longer an option,” he said, adding that police needed more resources and stronger powers.

However, organizations representing game animals called for caution. Marnie Lovejoy, deputy director of conservation British Shooting and Conservation AssociationHe said: “At this stage, no one knows the fate of this eagle, we hope it is found alive and healthy.

“As an organisation, we condemn the illegal killing of birds of prey without reservation, but what happened in this case is exactly what the investigation must reveal.”

Camilla Swift National Game Wardens Organization He said: “White-tailed eagles specifically have little impact on game birds or their breeding, and there is no evidence that a game warden was involved in any way.”

Snilesworth property management declined to comment. Andrew Gilruth, CEO Moorland AssociationHe said in a statement: “Once again, conclusions are being made before the facts are known. The loss of satellite signal does not prove what happened to the bird.”

“Taggings may fail, and activists may be embarrassed that birds they claim were killed by game wardens later turn out to be alive. Birds may also die naturally or become ill, and satellite tags may not be transmitted properly if affected by terrain or cover… Claims are not factual and speculation is not evidence.”

On the grounds, head game warden Charlie Woof was busy preparing for the charity clay pigeon shoot. He refused to make any comment about the missing eagle, and there is nothing to suggest that Woof or his team may have been involved in the eagle’s disappearance. The number of possible suspects is numerous, including local farmers and those connected to surrounding grouse estates.

Woof may also have been understandably publicity-shy after attracting national media attention as a young man. In 2008, as a 23-year-old young game warden on the same property, he pleaded guilty, along with the then chief game warden and another young game warden, to illegally trapping birds of prey using live pigeons as bait, for which he was fined £100.

“This is private property, I’m going to have to ask you to leave,” Woof said Thursday when asked about the missing eagle. “I don’t know anything about this.”
