How Often Do Bird Strikes Happen? Frequency, Risk & Prevention

Bird strikes occur daily in the United States, averaging roughly 50 to 60 reported incidents every single day. Yet the vast majority cause no injuries and no serious damage to aircraft. This article breaks down the real numbers, explains when and where bird strikes happen most, and shows what the aviation industry does to keep you safe.

Key Takeaways

• In the U.S., there are about 50–60 reported bird strikes per day, yet serious damage occurs in fewer than 5% of cases. Fatal bird strikes remain extremely rare due to stricter standards and management practices.
• The federal aviation administration recorded over 292,000 wildlife strikes with civil aircraft from 1990 to 2023, with about 19,700 in 2023 alone across roughly 780 U.S. airports.
• Most bird strikes occur below 3,000 feet during takeoff and landing phases, where aircraft and birds share the same airspace near ground level.
• From 1988 to 2024, wildlife strikes globally caused 499 fatalities and 361 aircraft destroyed – extremely uncommon outcomes given millions of safe flights each year.
• Airports, pilots, and regulators use layered bird strike prevention strategies – from habitat control to avian radar – that continue to drive down the percentage of damaging strikes.

What Is a Bird Strike?

According to the international civil aviation organization, a bird strike is a collision between a bird and an aircraft in flight, or during the takeoff or landing roll. The term is sometimes used interchangeably with wildlife strikes, which also cover bats, white tailed deer on runways, and other animals. However, birds account for over 95% of all wildlife strike incidents.

Common impact areas include jet engine inlets, windscreens, the nose or radome, wings, and flight control surfaces such as flaps, ailerons, elevators, and rudder. A strike can involve a single bird or an entire flock, with flocks dramatically increasing the risk of significant damage.

Typical consequences of bird strike incidents fall into three categories:

1. No damage – feather residue, a light mark, no operational effect. This is the most common outcome.
2. Minor damage – small dents or cosmetic issues requiring inspection; the flight may be delayed.
3. Serious damage – engine bird ingestion, windshield cracks, or structural harm. Rarely leads to an emergency landing or loss of the aircraft.

How Often Do Bird Strikes Happen? (The Numbers)

Airports report approximately 21,000 bird strikes annually in the United States. In 2023, the FAA National Wildlife Strike Database logged about 19,700 reported strikes at roughly 780 airports. In 2024, that number climbed to 22,372 – an average of about 61 per day.

For historical context, the strike database shows roughly 292,000 wildlife strikes with U.S. civil aircraft from 1990 through 2023. Over 17,000 wildlife strikes were recorded in the U.S. in 2019 alone. The upward trend in reported bird strikes reflects both better reporting practices and growing bird populations, not necessarily worsening safety.

Globally, the ICAO Bird Strike Information System captured 214,734 reports from 2022 to 2024 across 156 countries. But about 50% of bird strikes go unreported in the U.S., and underreporting is even higher internationally.

How often do these strikes actually cause harm? Less than 5% of reported cases result in damage aircraft situations, and an even smaller fraction lead to emergency landings or major incidents. Between 1990 and 2024, precautionary or emergency landings due to bird strikes totaled 9,375 incidents.

U.S. wildlife strikes (1990–2023)	~292,000
Reported strikes in 2024	22,372
Percentage causing damage (2024)	~3.7%
Global fatalities (1988–2024)	499

How Often Are Bird Strikes Serious or Cause Plane Crashes?

While bird collisions can damage aircraft, modern design and certification mean that plane crashes from bird strikes are exceptionally rare. Most aircraft are engineered with redundancy specifically to handle these events.

The data underscores this point: since 1988, wildlife strikes have resulted in over 293 deaths worldwide across both civil and military aviation. Bird strikes have resulted in 292 fatalities worldwide over 31 years. Against billions of passenger flights over that period, the individual risk is vanishingly small.

Only about 2% to 8% of bird strikes cause serious damage, depending on definitions, and fewer still result in loss of the aircraft. Two high-profile cases illustrate the extremes:

• Eastern Air Lines Flight 375 (1960): The aircraft crashed after striking a flock of European starlings on takeoff. All four engines suffered bird ingestion, resulting in 62 fatalities. This incident predates the modern strike database.
• US Airways Flight 1549 (2009): Both engines ingested Canada geese shortly after takeoff. Captain Chesley Sullenberger executed a water landing on the Hudson River with zero fatalities, demonstrating that even dual engine failure can be survived.

Why is the overall risk of a bird strike leading to a crash extremely low?

1. Modern engines are certified to withstand bird ingestion without catastrophic failure.
2. Twin-engine jets can fly safely on one engine.
3. Pilots receive extensive training for bird impact scenarios.
4. Airports invest in layered prevention that reduces serious consequences.
5. Air traffic control can reroute flights when bird activity is detected.

When and Where Do Bird Strikes Happen Most Often?

Bird strikes are not random. They cluster by altitude, phase of flight, season, time of day, and local airport environment. Understanding these patterns is central to aviation safety.

About 70% of strikes with fixed-wing civil aircraft occur between 0 and 500 feet above ground level, and more than 90% happen below 3,000 feet. Bird strikes occur more frequently at lower altitudes during takeoff and landing because that is where birds feed, roost, and commute.

Only around 3% of strikes with civil aircraft occur during the en route phase at cruising altitude, though rare events have been recorded at higher altitudes up to 32,000 feet. Roughly 61% of bird strikes happen during landing phases (approach and landing roll), and 36% during take off and climb – reflecting where birds and airplanes fly through the same airspace.

The following subsections explore migratory patterns, time of day, altitude, and surrounding environment in more detail.

Key Factors That Affect How Often Bird Strikes Occur

Migratory patterns, time of day, altitude, and local habitats all influence how frequently bird and wildlife strikes happen. Understanding these factors helps airports and regulators target bird strike prevention where it has the biggest impact.

Younger, inexperienced young birds and seasonal migrations produce predictable spikes in bird activity around airports. Each factor below offers concise, data-backed insight into how conditions change the probability of a strike.

The aim is to show patterns, not to alarm. The risk to an individual flight remains very low even during higher-risk periods.

Migratory Patterns and Seasonal Peaks

Bird strikes are more common during spring and fall migrations, when dense flocks travel along established flyways that often overlap with airport locations. Strikes peak from July to October due to seasonal migrations and juvenile fledging – about 54% of all U.S. bird strikes occur in this window.

Most bird strikes involve large birds like geese and gulls, which contribute disproportionately to serious damage. In the U.S., 30% of strikes are from waterfowl. Turkey vultures are identified as the most damaging birds in terms of strike severity, while Canada geese can weigh up to 14 pounds, increasing strike severity dramatically. Reported strikes mainly involve mourning doves and horned larks by sheer volume, though these small birds cause far less damage.

High-risk months for temperate North America:

1. July–August – young birds fledge and are inexperienced near airports.
2. September–October – fall migration peaks; more birds at low altitudes in flight corridors.
3. March–April – spring migration brings returning bird species northward.

Many airports monitor local migratory patterns to time intensified wildlife management and adjust operations.

Time of Day

Roughly 62% of bird strikes occur during daylight hours, about 8% at dawn or dusk, and around 30% at night, based on FAA data. Most bird species are diurnal, leading to more daytime bird collisions, while nocturnal species such as owls account for some nighttime strikes.

Notably, bird strikes are about seven times more common at night during migration periods, when large numbers of birds move through airspace under cover of darkness. Reduced visibility at night makes it harder for both birds and an airline pilot to detect each other. Airports use visual deterrents and aircraft lighting as mitigation tools during these hours.

Time of Day	% of Bird Strikes
Daytime	~62%
Night	~30%
Dawn/Dusk	~8%

These time-of-day patterns directly inform airport scheduling and bird strike prevention planning.

Altitude and Phase of Flight

The vast majority of bird strikes happen near the ground. About 70% occur below 500 feet, and more than 90% below 3,000 feet above ground level. Birds typically fly at low altitudes for feeding and commuting, overlapping with commercial aircraft during takeoff and landing.

At higher altitudes, strikes become very rare. The FAA recorded only 31 strikes between 20,000 and 32,000 feet from 1990 to 2023 – usually involving migratory species pushed upward by weather. Extraordinary reports exist of bird hits at roughly 37,000 feet.

Interestingly, lower speeds during the landing phases can reduce the kinetic energy of impacts, potentially limiting damage. Conversely, during climb-out at high thrust, engine bird ingestion poses greater risk because fan blades are spinning at full power.

Surrounding Environment and Air Traffic

Airports near water bodies have higher bird strike risks. Coastlines, rivers, lakes, wetlands, landfills, and agricultural fields all attract bird species that create hazards. The presence of food and shelter increases bird strike probability at airports – open water, food waste, crops, and roosting trees draw waterfowl, gulls, raptors, and flocking species into the airport environment.

Increasing global air traffic means more aircraft movements through bird habitats, raising the absolute number of reported strikes even if individual-flight risk stays constant. Airport wildlife hazard management focuses on habitat modification – drainage, grass management, waste control – to make the area less attractive.

One practical innovation: shade balls, which are black plastic spheres placed over open water features, reduce bird strikes by covering ponds that would otherwise attract waterfowl. Several airports have adopted this low-cost solution to discourage birds from congregating near runways.

How Bird Strikes Damage Aircraft (And Why Most Flights Stay Safe)

Most bird strikes cause little or no damage. But certain aircraft components are more vulnerable and can suffer varying degrees of impact. The bird’s size, the number of birds, aircraft speed, and exact species all determine severity.

Key vulnerable areas ranked by approximate frequency of damage:

Component	Approx. Share of Damaging Strikes
Engines / nacelles	~25%
Wings / leading edges	~25%
Windscreens / nose	~20%
Fuselage	~15%
Flight control surfaces / sensors	~15%

The following subsections focus on what happens when each area is hit.

Engines and Propellers

A jet engine can ingest birds, damaging fan blades and disrupting airflow. This can lead to thrust loss or engine failure, leading to emergency landings. Certification standards require engines to survive impacts from birds weighing up to about 4 pounds without catastrophic failure.

Most modern twin-engine jets are designed to safely continue flight after losing one engine, making dual engine failure from bird strikes extremely rare. The US Airways Flight 1549 incident – where both engines ingested Canada geese – remains an extreme outlier. Even then, the aircraft landed safely.

For propeller aircraft, bird hits can bend or break blades, causing vibration, loss of thrust, and possible engine damage. Larger birds and flocks amplify these risks considerably.

Windscreens, Nose, and Fuselage

Windscreens face very high bird impact forces because of combined bird and aircraft speed, sometimes exceeding 160 mph at collision. Modern cockpit windows use layered glass and strong framing, but high-speed impacts can still cause cracking. A cracked cockpit window can cost up to $90,000 to repair.

Nose cones and leading edges can be dented or punctured, affecting aerodynamics. Although damage can look dramatic in photos, structural redundancy and established procedures generally keep passengers safe. In most cases, the crew makes a precautionary diversion, airport personnel inspect the aircraft, and passengers deplane without incident.

Flight Control Surfaces and Sensors

Flight control surfaces – ailerons, elevators, rudder, flaps, slats, spoilers – are critical to maneuverability and flight control. Bird strikes to extended flaps or slats during takeoff and landing are more likely because these surfaces protrude into the airflow.

Potential effects include dented or jammed hinges, damaged skins, and birds lodged in mechanisms that limit movement. Probes and sensors near the nose can also be hit, disrupting air data for instruments and automated flight control systems, though backup sensors usually exist.

Post-strike inspections focus heavily on these areas. No aircraft returns to service until airport personnel and maintenance crews confirm full control authority.

How the Aviation Industry Works to Prevent Bird Strikes

Bird strike prevention is a layered system combining airport wildlife management, aircraft design, operational procedures, and regulatory oversight. The aim is to reduce both the frequency of bird strikes and the serious consequences when they occur.

Modern prevention prioritizes humane, science-based methods. Collecting and analyzing strike data is central to continuous improvement. The FAA invests approximately $400 million through Airport Improvement Program grants toward wildlife hazard mitigation.

Airport Wildlife Management and Habitat Control

Core strategies include modifying habitats so the airport environment is unattractive to birds. Turfgrass should be managed to reduce bird attraction – keeping grass at specific heights discourages ground-feeding species. Standing water is drained or covered. Waste management is secured.

Common non-lethal deterrents and harassment techniques include:

• Pyrotechnics and propane exploders – create loud noises to scare birds away from runways
• Bird-repelling sound systems – broadcast distress calls or predator sounds to deter birds from airports
• Lasers and visual deterrents – disrupt roosting and feeding
• Trained dogs and falconry – active patrols that move birds along in the same direction, away from flight paths

Lethal control is sometimes used as a last resort when non-lethal methods fail, within integrated plans guided by the USDA wildlife service. Many airports develop Wildlife Hazard Management Plans based on local species and migratory patterns, following FAA and APHIS guidance.

The transportation research board has published research showing that comprehensive habitat management at mid-size airports can reduce strike rates by 50% or more within a few years.

Technology: Radar, Sensors, and Flight Control Support

Avian radar tracks birds near airports to prevent strikes by giving controllers and pilots real-time data on bird movements. Some Doppler weather radar data can also identify dense bird activity along flight routes.

Aircraft lights and painted engine spinners increase visibility, helping birds detect and avoid approaching aircraft. Some research suggests that flying with landing lights on during climb-out helps birds move out of the flight path.

Flight control systems and cockpit procedures include checklists for suspected or confirmed bird strike events. After a bird impact, crews follow standardized steps to verify system integrity and decide whether to continue or divert – maintaining flight safety throughout.

Reporting, Data, and Continuous Improvement

Mandatory and voluntary reporting to the national wildlife strike database and ICAO’s global system is the backbone of prevention improvement. Each report captures the date, location, exact species when possible, phase of flight, altitude, and damage level.

Specialists from the USDA wildlife service and the Smithsonian Feather Identification Lab often identify bird species from feather or tissue remains. This helps pinpoint which species cause the most other wildlife strikes and bird deaths, guiding targeted management.

Data trends are encouraging. Average bird mass involved in strikes has decreased about 64% from 2000 to 2024, meaning more birds being struck are small birds rather than larger birds. The damage percentage has also fallen, even as total reported strikes rise.

This data informs updates to bird strike prevention strategies, aircraft certification standards, and airport wildlife programs – a continuous loop of reporting, analysis, and action.

Conclusion: How Worried Should Passengers Be About Bird Strikes?

Bird strikes are frequent events in aviation statistics – tens happen every day in the U.S. alone. But for passengers, the actual risk of a serious incident is extraordinarily low. Only a tiny fraction of strikes cause serious damage, and the number leading to plane crashes is negligible compared to the millions of safe flights completed each year.

Aircraft are engineered and tested to withstand bird impact. Airports invest heavily in prevent bird strikes programs and wildlife management. The first reported bird strike dates back to 1905, and over more than a century, the industry has developed layered defenses that continue to improve. Bird and wildlife strikes cost an estimated $900 million annually to U.S. civil and military aircraft, and bird strikes cost the aviation industry $1 billion annually worldwide – numbers that underscore just how seriously the industry takes this risk. Repair costs from bird strikes can reach $500 million per year in the U.S.

View bird strikes as a managed safety risk, not a reason to avoid flying. Modern air travel remains overwhelmingly safe.

Bird strikes happen every day, but thanks to modern aircraft design, pilot training, and airport wildlife management, they rarely result in serious accidents. While most flights continue safely after a bird strike, passengers who suffer injuries during an airplane accident or in-flight incident may have legal rights.

FAQs About How Often Do Bird Strikes Happen

These FAQs address common concerns that passengers and aviation enthusiasts raise about bird strikes, expanding on topics not fully covered above.

What does a bird strike feel like for passengers on board?

Many passengers never notice minor bird strikes at all. At most, you might hear a dull thump or feel a brief vibration during takeoff or landing. The sound is often compared to a small object hitting a car windshield.

Pilots typically continue the flight if all systems read normal. If there is any doubt, the crew will return to the airport for inspection as a precaution. Cabin crews are trained to keep passengers informed and calm if a suspected strike occurs. Visible damage – such as dents on the nose – is usually only seen after landing, once passengers disembark.

How expensive is a typical bird strike for airlines?

In the U.S., bird and wildlife strikes cost airlines hundreds of millions of dollars annually in repairs, inspections, and delays. The FAA estimates adjusted costs of around $300 million per year when accounting for unreported incidents.

Minor strikes might only require inspection and cosmetic repair. Severe engine damage can remove an aircraft from service for days or weeks. Costs include parts, labor, and lost revenue from cancelled or delayed flights. These economic impacts are a major reason airlines and airports invest in bird strike prevention programs.

Are smaller planes more vulnerable to bird strikes than large jets?

Small general aviation aircraft often fly at low altitudes and slower speeds, where more birds are present, and they lack the redundancy of large airliners. A bird impact on a small aircraft’s windscreen or flight control surfaces can be more disruptive relative to its size and structural strength.

Large transport-category commercial aircraft are certified to rigorous bird impact standards and have multiple systems for redundancy. While most aircraft in both categories handle strikes safely, smaller planes are statistically more affected by a given impact. Pilots in all categories receive bird strike awareness and response training.

What training do pilots receive for dealing with bird strikes?

Pilot training includes classroom instruction and simulator scenarios covering bird strike recognition, instrument checks, and appropriate checklists. For engine bird ingestion events, crews practice procedures such as engine shutdown, single-engine approaches, and emergency landings.

Pilots also learn avoidance strategies: adjusting climb profiles, using lights, and following air traffic control advisories about local bird activity. These standardized procedures help ensure calm, predictable responses that maintain flight safety even after a significant bird impact.

Do changing bird populations and climate patterns affect bird strike risk?

Yes. Some bird species – including Canada geese and certain gulls – have increased in number near urban areas and airports, contributing to higher strike exposure. Other wildlife such as certain raptor populations have also grown near airfields.

Shifts in migratory patterns and milder winters can change when and where birds are present. Airplanes fly through airspace that is increasingly shared with expanding bird populations. Ongoing research examines how climate trends influence bird movements and what that means for long-term prevention planning. Continuous monitoring and updated wildlife management programs are designed to keep bird strike risk low despite these environmental changes.
