A juvenile hen harrier’s satellite tag goes silent every spring somewhere on a heather-covered hillside in northern England or the Scottish uplands. No signal, no last known coordinates that veered off onto a road or a lake. Nothing at all. Tracking these birds has led conservationists to identify the pattern. Seldom does it indicate that the tag broke.
The moors themselves are stunning, almost theatrically so; they are rolling, purple-brown, and littered with Land Rover paths that twist up toward the horizon and grouse butts. It’s understandable why shooting there costs tens of thousands of pounds per day. The argument is that what happens to the birds that compete with red grouse for food and space is more difficult to observe. There is no trace left by raptors. That’s actually the issue.
Occasionally, gamekeepers have been detected using bait laced with carbofuran, a poisonous chemical that has been outlawed in the UK since 2001, or pole traps set to snap shut on a bird’s legs. There are prosecutions. They are just uncommon, and convictions that last are much more uncommon. Estates operate on vast, frequently isolated tracts of land, and the proof is typically circumstantial—a dead buzzard here, a tag that ceases to transmit there. This type of crime is designed to be plausibly denied.
Those who have witnessed this for decades feel that persecution has become almost entirely localized. The same clusters—parts of the Yorkshire Dales, the Angus Glens, and the Monadhliath Mountains—continue to be identified by independent tracking studies as having persistently lower hen harrier survival rates than other areas. It is not evidence of the culpability of any one estate. However, the pattern is so persistent that most people who properly examine it no longer consider it to be a coincidence.
For their part, shooting organizations continue to maintain that the industry has gotten past all of that. They claim that zero tolerance refers to rogue individuals rather than systemic practices. It’s a statement that has been used for years, and many landowners may even mean it. However, the birds continue to vanish at rates that don’t fully correspond with the rhetoric. It’s difficult to ignore the fact that the discrepancy between declared policy and actual results has hardly decreased, and something isn’t adding up.
Scotland made an alternative attempt. The Muirburn Act established grouse shoot licensing, which means that if a wildlife crime is linked to an estate, it may theoretically lose its ability to operate. It’s unclear if that will actually alter behavior on the ground because the law is still in its infancy and enforcement relies on resources that no one is certain exist. Wales and England, however, lack such a system. For years, activists have lobbied for one, mostly in vain.
When seeing this from a distance, it’s remarkable how silent the entire thing remains. There won’t be any riots or stories that last longer than a news cycle. Just a steady, grinding attrition—one poisoned carcass at a time, a species driven toward local extinction on what seems to be completely untouched territory from any reasonable distance. Hen harriers’ survival on English moors will probably depend on whether licensing reform goes south or if it stays a Scottish experiment.
