A bird strike, also known as avian strike or wildlife strike, is a collision between an aircraft and one or more birds. While often minor, bird strikes can cause significant damage to engines, windshields, and critical flight systems—making them a serious safety concern in global aviation.
In this comprehensive guide, we break down everything you need to know about bird strikes, including how they happen, why they matter, real-world incident data, and the modern technologies helping to reduce them.
Bird Strike
What Is a Bird Strike?
A bird strike occurs when a bird impacts an aircraft during any phase of flight, most commonly:
Takeoff
Climb
Landing
Approach
These events usually happen near airports where birds naturally gather—wetlands, grasslands, landfills, or food-rich areas.
Bird strikes are a global issue affecting:
Commercial airlines
Private pilots
Military jets
Helicopters
Cargo aircraft
Why Bird Strikes Happen
1. Overlapping Airspace
Birds and aircraft share low-altitude airspace, especially below 3,000 ft, where birds are most active.
2. Migration Patterns
Millions of birds migrate during spring and fall, increasing risk for pilots flying through migratory routes.
3. Bird Habitats Near Airports
Airports located near:
Wetlands
Foliage-rich areas
Open fields
Dump yards
Coastal zones
tend to attract large bird populations.
4. Engine Suction
Modern jet engines generate strong air suction, drawing birds inside—especially during takeoff when thrust is highest.
How Dangerous Are Bird Strikes?
While most bird strikes cause little damage, large birds or multiple birds entering an engine can create severe hazards.
Major risks include:
Engine failure or engine flameout
Broken cockpit windshields
Damage to leading edges & wings
Pitot tube blockage
Loss of thrust on takeoff
Fuel line or wiring damage
Large bird species (geese, vultures, swans, kites) pose the highest risk.
What Happens When a Bird Hits an Aircraft?
The impact depends on:
Bird size
Aircraft speed
Point of impact
Common impact areas:
Engines
Nose cone
Cockpit windshield
Wing leading edges
Landing gear
Vertical stabilizer
Jet engines are tested to withstand bird ingestion, but large birds or multiple birds can overwhelm them.
How Pilots Handle Bird Strikes
Pilot actions may include:
Maintaining aircraft control
Declaring emergency (Mayday/Pan-Pan)
Returning to departure airport
Shutting down damaged engine
Running engine failure checklists
Avoiding further climbs to minimize stress on remaining systems
Major airlines train pilots extensively for wildlife strike scenarios.
How Airports Prevent Bird Strikes
Airports use multi-layered Wildlife Hazard Management Programs to reduce risk.
1. Habitat Modification
Removing standing water
Cutting grass to reduce rodents
Reducing food waste
Eliminating perching areas
2. Bird Deterrent Systems
Laser deterrents
Propane cannons
Pyrotechnics
Ultrasonic devices
Hawk-like drones
Trained falcons
Bio-acoustic alarm calls
3. Radar Technology
Bird Detection Radar Systems (BDRS) track real-time bird movement so ATC can:
Delay takeoff
Change runway
Adjust flight paths
4. Engine & Aircraft Engineering
Bird-resistant windshields
Reinforced engine blade designs
Ingestion-tested turbofan systems
5. Data Monitoring
Airports log and analyze bird strikes to identify patterns and risks.
Types of Birds Most Frequently Involved in Strikes
Gulls
Pigeons
Geese
Hawks
Crows
Vultures
Starlings
Kites
Swallows
Large birds cause the most damage due to weight and body density.
Seasonal Patterns of Bird Strikes
Bird activity varies throughout the year:
Spring & Fall → High migration, highest risk
Summer → Juvenile birds learning to fly
Winter → Birds gather near warm zones (runways, engine heat areas)
Modern Technologies Fighting Bird Strikes in 2025
Aviation is rapidly improving bird-strike prevention with smart technologies.
AI-Powered Wildlife Management
AI identifies bird species, predicts movement, and triggers deterrent systems automatically.
Drone-Based Bird Scare Systems
Drones shaped like hawks patrol the airfield and scare off birds.
Smart Runway Lighting
Special LED patterns deter nocturnal birds and insects.
Laser Barriers
Harmless laser lines guide birds away from flight paths.
Autonomous Ground Vehicles
Robots patrol runways to chase birds and collect data.
Are Bird Strikes Preventable?
Completely preventing bird strikes is impossible due to natural ecosystems and migration.
However, modern wildlife management systems significantly reduce both:
Frequency
Severity
Airports worldwide report declining serious incidents thanks to better technology and habitat control.
Conclusion
Bird Strikes Remain One of Aviation’s Natural Challenges
Bird strikes are a longstanding aviation hazard—but one the industry manages extremely well.
Through smarter technology, stronger aircraft design, and advanced wildlife management, the risk of catastrophic bird strikes continues to decrease.
Still, ongoing research and innovation are essential as global air traffic increases.
