How Common And Dangerous Are Bird Strikes in British Aviation?

The UK’s former Central Science Laboratory estimated that worldwide, bird strikes cost airlines around $1.2 billion annually. The UK Civil Aviation Authority (CAA) recorded 1,432 bird strikes across British aviation in 2022, and the agency has tracked a steady rise in reporting since mandatory disclosure began in January 2004. The deadliest confirmed case in recent British history killed four US Air Force airmen when their helicopter struck a flock of geese over the Norfolk coast in January 2014.

How Many Bird Strikes Does the UK Record Each Year

The CAA’s Birdstrike Risk Management data shows that approximately 2,000 strikes are reported to the regulator annually, of which around 1,400 are classified as “confirmed” incidents involving physical evidence of a collision. In 2022, the confirmed figure stood at 1,432, with the CAA recording an average rate of 256 bird strikes per 10,000 aircraft movements that July. Of those 2022 incidents, only 45 caused damage to the aircraft, and just 28 resulted in a flight return or diversion.

Reporting volumes rose sharply after January 2004, when the CAA made disclosure of bird strikes mandatory for aircrew. That change alone drove a 60% increase in the number of reports received. By 2016, confirmed strikes had climbed to 1,835 for the year, according to CAA figures cited in contemporary reporting. Serious strike events — those causing damage or measurably affecting a flight — have held relatively steady at 55 to 60 occurrences per year, even as overall traffic volumes have grown.

The most commonly struck species in UK airspace are gulls, wood pigeons, pigeons, and skylarks, alongside swallows, swifts, and kestrels in some seasonal reporting periods. Around 85% of UK bird strikes occur below 800 feet.

Which Airports Face the Highest Risk

Heathrow Airport (LHR) operates one of the most intensive bird hazard management programmes of any British airport. The airport runs a bird scaring operation 24 hours a day, 365 days a year, using an electronic system called Digiscare that broadcasts pre-programmed distress calls tailored to different species.

Gatwick Airport (LGW) and Luton Airport (LTN) have also recorded serious incidents. A CAA report covering 2011 and 2012 documented 315 bird strike incidents that either damaged aircraft or created a flight safety hazard.

Not every bird poses the same level of threat. Risk depends on a combination of body mass, flocking behaviour, and how frequently a species is encountered near runways. UK data consistently identifies a small group of species as responsible for the bulk of confirmed strikes:

• Gulls
• Wood pigeons and pigeons
• Skylarks, swallows, and swifts
• Kestrels and other raptors

RAF Lakenheath: Britain’s Deadliest Confirmed Bird Strike Accident

On the night of January 7, 2014, a US Air Force HH-60G Pave Hawk helicopter from the 56th Rescue Squadron, based at RAF Lakenheath in Suffolk, crashed into marshland near Cley next the Sea in Norfolk. All four crew members were killed.

The helicopter was flying at approximately 110 feet above ground level at around 110 knots during a nighttime training exercise when it passed low over Cley Marshes, a nature reserve known for large resident bird populations. A flock of geese, startled by the noise of two approaching helicopters, took flight directly into the aircraft’s path. At least three geese struck the windscreen, rendering both the pilot and co-pilot unconscious, while a separate strike disabled the trim and flight stabilisation systems.

How The Military Manages Bird Strikes Across The RAF

The Royal Air Force (RAF) treats bird strikes as a significant and ongoing safety concern across its UK basing network. More than 250 bird strikes or near-misses were recorded at RAF bases in the Southern and Eastern regions between 2017 and October 2021, including 73 incidents in 2020 alone. In response, the Ministry of Defence issued contracts worth more than £7 million in 2021 for dedicated wildlife control services covering stations including RAF Brize Norton, RAF Coningsby, RAF Marham, and RAF Waddington.

Military aircrew have experienced dramatic incidents in recent years. In August 2022, a Red Arrows pilot, Squadron Leader Gregor Ogston, suffered a bird strike during a display at the Rhyl Air Show that shattered his aircraft’s cockpit canopy, sending glass and bird remains into the cockpit.

He safely landed the damaged jet at Hawarden Airport and was later presented with the RAF’s highest flight safety award, the Green Endorsement. In January 2025, a RAF Eurofighter Typhoon from RAF Coningsby suffered a suspected bird strike over north Wales that led the pilot to jettison the aircraft’s canopy before completing an emergency landing back at base.

How UK Regulators Manage Bird Strike Risk

British aerodrome operators are required under CAA regulation to establish procedures that minimise the risk of collisions between wildlife and aircraft. The principal guidance document, CAP 772: Wildlife Hazard Management at Aerodromes, sets out how airports should build and maintain a Bird Control Management Plan, covering risk assessment, habitat management, and species-specific mitigation measures.

CAP 772 recommends a structured approach that includes:

• Habitat modification to reduce food sources and nesting sites near runways
• Restrictions on agricultural activity, such as ploughing or manure spreading, close to aerodromes
• Use of lasers, distress calls, and trained personnel for active bird dispersal
• A tiered risk-scoring system that raises a species’ hazard rating after repeated multiple-bird strikes
