Shot, Poisoned, and Trapped: Why Britain's Protected Birds of Prey Keep Dying

In October 2024, the RSPB published its annual Birdcrime report and confirmed what conservationists had long suspected: the illegal killing of birds of prey in Britain is not a relic of the past but an ongoing, systematic problem. Between 2009 and 2023, the charity recorded 1,529 confirmed persecution incidents and at least 1,344 individual raptors illegally killed [1]. The true figure, the RSPB says, is far higher — confirmed cases represent "just the tip of the iceberg" because the crimes occur in remote, sparsely populated uplands where carcasses are rarely found [2].

The methods are brutal. Birds are shot, trapped in illegal spring traps, and poisoned with banned pesticides. In one case documented during the 2023 reporting period, a hen harrier had its head pulled from its body while still alive [2]. In another, a young white-tailed eagle from the Isle of Wight reintroduction programme — the first of its species to breed in England since the 18th century — was poisoned on a West Sussex shooting estate with Bendiocarb, a pesticide banned for decades [3].

The Scale of the Problem

The RSPB's Birdcrime data, collected since 1990, provides the most comprehensive longitudinal record of raptor persecution in Britain. In 2023, 59 confirmed incidents were recorded — slightly down from 61 in 2022 but consistent with a long-running pattern [1]. The year 2020 saw a record 137 confirmed incidents, the highest in over three decades of monitoring [1].

Over the 15-year period from 2009 to 2023, 506 confirmed incidents involved illegal poisons, affecting at least 488 birds of prey including golden eagles, red kites, buzzards, sparrowhawks, and peregrines [2]. Species targeted span the full range of British raptors: golden eagles, hen harriers, peregrine falcons, goshawks, white-tailed eagles, red kites, buzzards, sparrowhawks, barn owls, and short-eared owls [1].

The hen harrier — a medium-sized raptor that hunts grouse chicks across open moorland — is proportionally the most affected species relative to its population size. A peer-reviewed study by Ewing et al., published in Biological Conservation in 2023, found that illegal killing associated with gamebird management accounts for up to 75% of annual hen harrier mortality [4]. Among birds aged one to two years, 75% of deaths were attributed to illegal persecution [4]. Satellite-tagged hen harriers survived an average of just four months [5].

Hen Harriers: A Population Under Pressure

The 2023 national hen harrier survey counted 691 territorial pairs across the UK and Isle of Man, up from a low of 545 in 2016 but still well below the 749 pairs recorded in 2004 [6]. The current population represents approximately 25% of what the available habitat could support — meaning roughly three-quarters of suitable breeding territory remains unoccupied [7].

The distribution tells its own story. Scotland holds 77% of the UK population with 529 pairs [6]. England saw a notable recovery from just 4 pairs in 2016 to 50 in 2023 [6]. But hen harriers remain absent from the Peak District and the North York Moors despite extensive suitable habitat — areas dominated by grouse moor management [7]. Wales held 40 pairs, while Northern Ireland declined by 26% to 34 pairs, a drop attributed partly to habitat loss [6].

Between 2010 and 2024, 112 satellite-tagged hen harriers disappeared under suspicious circumstances across the UK, with the majority sending their final transmission on or near land managed for grouse shooting [5]. In 2023 alone, 32 satellite-tagged birds vanished or were confirmed illegally killed in England — the highest single-year figure ever recorded [5].

Geographic Hotspots and the Grouse Moor Connection

Raptor persecution incidents cluster in specific geographic areas, and those areas overlap with land intensively managed for driven grouse shooting.

Swaledale in the Yorkshire Dales National Park is statistically the worst location in England for hen harrier persecution. Between 2016 and 2023, three hen harriers were confirmed illegally killed and 14 satellite-tagged birds suspiciously disappeared there [8]. Near Birkdale in North Yorkshire alone, eight satellite-tagged birds were persecuted or vanished [8]. In 2024, hen harrier breeding in the Yorkshire Dales declined by 73% compared to the previous year, with the North Pennines seeing a 67% decline [8].

The connection to gamebird shooting is not merely geographic. Of all individuals convicted of raptor persecution offences between 2009 and 2023, 75% were connected to the gamebird shooting industry [1]. In 2022, 64% of all confirmed incidents were associated with land managed for gamebird shooting, consistent with rates of 62% in 2020 and 71% in 2021 [1].

Who Is Responsible? The Evidence and the Pushback

The RSPB's data points overwhelmingly toward gamekeepers on driven grouse moors as the primary actors. But the shooting industry contests this narrative.

The Moorland Association and other industry groups argue that the RSPB's methodology conflates correlation with causation. A bird disappearing on a grouse moor does not prove a gamekeeper killed it — satellite tags can fail, and birds can die from natural causes or collide with wind turbines and powerlines [9]. Industry representatives note that some confirmed killings involve pigeon fanciers (who target peregrines that prey on racing pigeons) and farmers protecting livestock, rather than gamekeepers [9].

Wild Justice, a conservation charity co-founded by naturalist Chris Packham, has funded 68 police investigations into suspected raptor persecution since October 2020, paying for 43 post-mortems, 29 x-rays, a CT scan, and two DNA profiling tests [10]. Of those 68 investigations, eight resulted in prosecutions and convictions. Seven of the eight convicted individuals were gamekeepers on pheasant shoots; one was a local resident [10].

The Ewing et al. study provides further independent evidence. Using satellite-tracking data and survival analysis, the researchers found that mortality due to illegal persecution was significantly higher in areas managed for grouse shooting than elsewhere [4]. The study controlled for other causes of death including natural mortality, collision with infrastructure, and disease.

However, some academic critics have noted that satellite-tag studies inherently sample only tagged birds, which are more likely to be found near areas of conservation interest — introducing a possible spatial bias. The shooting industry has repeatedly called for independent verification of RSPB data, arguing the charity has a campaigning agenda that colours its analysis [9].

The Economics of Driven Grouse Shooting

Defenders of driven grouse shooting point to its economic contribution to rural communities. The Moorland Association estimates the industry generates at least £23.3 million annually for the rural economy, supports 1,500 full-time posts and 42,500 working days per year in England, and channels approximately £1 million per week in private investment into moor management [9]. In Scotland, the industry claims £23 million in gross value added to the economy [9].

An independent analysis commissioned by the RSPB and authored by economist Matt Rayment reached different conclusions. The report estimated total employment across the sector and its supply chain at approximately 4,000 full-time equivalent jobs across the UK — described as "less than one-tenth of one percent of rural employment" [11]. The report found that driven grouse shooting estates "appear to make a loss" financially, with estates supplementing income through subsidies tied to sheep farming on the same land [11].

Approximately 310 estates in Great Britain manage between 0.8 and 1.8 million hectares for grouse shooting — 190 in England and 120 in Scotland [11]. Case studies at Geltsdale and Langholm demonstrated that former grouse moors transitioned to conservation and tourism "replaced jobs lost for gamekeepers with new jobs" in those sectors [11].

Alternative land use economics further complicate the industry's case. Research cited by the Wild Moors campaign found that restored upland peatlands could be worth more than four times the economic value of grouse shooting, with peatland restoration valued at over £470 million [12]. With carbon offsetting schemes, restoration costs could be recovered within the first year [12].

In June 2025, Parliament debated driven grouse shooting, with MPs raising concerns about both the environmental and economic arguments for the status quo [13].

Prosecution Rates and Enforcement Gaps

Even when raptor killings are confirmed, prosecutions are rare and convictions rarer still. In 2017, 68 confirmed incidents produced only four prosecutions and a single conviction [1]. Over the entire 15-year period from 2009 to 2023, only one person has been jailed for raptor persecution crimes [1]. In 2022, two successful convictions — both gamekeepers — resulted in penalties that critics described as derisory: one received a 200-hour community order and was ordered to pay just £1,200 in fines, costs, and compensation despite multiple birds being shot or poisoned [10].

The barriers to prosecution are structural. Investigatory decisions rest entirely with local police forces, and the National Wildlife Crime Unit and Natural England specialists can assist only if invited [14]. Wild Justice has described cases sitting with police "for months, sometimes for over a year" due to forces being overstretched, lacking specialist expertise, or — in the charity's view — having "corrupt vested interests" [10].

Raptor persecution is listed as one of the UK Wildlife Crime Priorities by the National Wildlife Crime Unit, but that designation does not come with dedicated funding or guaranteed investigative resources [14]. Immediate forensic work — x-rays and post-mortems in the critical early hours after a bird is found — often depends on charitable funding rather than state resources [10].

Proving criminal intent adds further difficulty. Prosecutors must show not only that a bird was illegally killed but that the defendant knew their actions were illegal, intended to kill a protected species, and — in the case of landowners — had knowledge of what was happening on their land [14]. These evidentiary thresholds, combined with the remote locations where crimes occur and the absence of witnesses, make convictions structurally unlikely.

The Legislative Gap: Vicarious Liability

Scotland introduced vicarious liability for wildlife crimes on 1 January 2012 through the Wildlife and Natural Environment (Scotland) Act 2011, allowing employers to be prosecuted when an employee illegally kills a bird of prey [15]. The employer has a defence if they can show they did not know an offence was being committed and took all reasonable steps to prevent it [15].

Has it worked? The record is mixed. To date, only two successful prosecutions have been brought under the vicarious liability provisions, and neither involved wildlife crime on a driven grouse moor [15]. Critics argue this shows the provision has insufficient enforcement behind it. Supporters counter that the law's deterrent effect — creating financial and reputational risk for estate owners — has shifted management culture even if prosecutions remain rare.

Scotland has since gone further. The Wildlife Management and Muirburn (Scotland) Act 2024, which received Royal Assent on 30 April 2024, requires all grouse shoots in Scotland to hold a licence, which can be revoked if a crime is committed [16]. When NatureScot initially narrowed the licensable area to just the spot where grouse are "taken or killed" rather than the entire estate, conservationists identified this as a loophole. The Natural Environment (Scotland) Act 2026 closed it by amending the wording so that a licence can be suspended or revoked if a relevant offence "supports or benefits the activities permitted by the licence," regardless of where on the estate it occurred [17].

England has no equivalent legislation. Conservationists have petitioned Parliament to introduce vicarious liability, and the issue has been debated in Westminster, but the government has not committed to legislation [18]. Officials have stated they are "watching to see how well it works in Scotland" — a position critics describe as indefinite delay [18].

International Context

Britain's raptor persecution problem is distinct within Europe in being closely tied to a single industry. Across the Mediterranean, an estimated one billion migratory birds are illegally shot and trapped annually, including roughly 100,000 raptors [19]. In Spain, government-organised boards systematised raptor killing through the mid-20th century [19]. The Eurasian buzzard and northern goshawk are the most frequently illegally killed raptor species across Europe as a whole [19].

The EU Birds Directive (1979) provides legal protection across member states, but enforcement varies widely [19]. Britain's situation differs because the documented persecution is concentrated in specific landscapes managed for a specific commercial activity, rather than arising from a broader hunting culture. This concentration, paradoxically, should make the problem easier to address through targeted regulation — if the political will exists.

Ireland, which shares some raptor species with Britain, has seen lower documented persecution rates but has also invested less in satellite tagging and monitoring, making direct comparison difficult. Germany and Spain both face ongoing raptor persecution linked to game-shooting interests, though the species mix and land-management models differ substantially [19].

The Ecological Cost

The suppression of raptor populations has consequences beyond the species themselves. Raptors are apex predators whose presence shapes prey populations and, through trophic cascades, influences vegetation structure, invertebrate communities, and broader ecosystem health.

Hen harriers, for example, regulate populations of small mammals and ground-nesting birds on moorland. Their absence from areas like the Peak District — where they should naturally breed — represents a measurable ecological deficit. Population modelling suggests that if illegal killing were fully eliminated, hen harrier numbers could recover to approximately 2,600–2,800 territorial pairs across the UK within 10–15 years, quadrupling the current population [7].

Red kites, which were driven to near-extinction in Britain by the early 20th century, have recovered strongly through reintroduction programmes — but continue to be poisoned, particularly in Scotland and northern England. Golden eagles remain functionally absent from large areas of suitable habitat in the Scottish Highlands and are absent from England entirely, despite historical breeding records [2].

The question facing Britain is not whether raptor persecution is occurring — the evidence on that point is extensive and peer-reviewed. The question is whether the political and legal systems will act on what the science has established, or whether protected species will continue to be killed with near-impunity in the uplands they are supposed to inhabit.
