Birds stuck inside airport terminals can be challenging to remove. Birds often enter airports through automated doors or loading docks that are left open for extended periods. While some airports opt for humane traps to catch and release birds, others may resort to lethal methods. Bird strikes on planes can be dangerous, so airports employ various strategies to prevent them, including firing air cannons, altering landscapes, and deploying technology like advanced radar systems and LED screens with googly eyes to scare birds away. Additionally, companies like Meridian Bird Removal specialize in bird control services, offering rapid interior live capture systems to remove birds from airports and other large facilities.

What You'll Learn
Birds are trapped and released outside
Birds stuck inside airport terminals can be challenging to remove. Birds often enter airports through automated doors or loading docks that remain open for extended periods. While most airports cannot afford to spend time and resources on trapping and releasing birds outside, some airports do employ this method. For instance, the Chicago Bird Collision Monitor, a firm that was called to remove birds from O'Hare airport, suggested the use of humane traps to catch the birds and release them outside. Similarly, a CDA spokesman stated that the CDA uses humane traps and works with either the USDA or a contracted firm to safely remove birds from airport grounds.
Meridian Bird Removal is another company that provides bird removal services for airports. They have developed a unique method with custom-built, patented equipment to safely and effectively capture birds. Their process involves scouting the area, strategically placing nets, and constantly monitoring them to immediately remove birds.
In addition to trapping and releasing birds, airports employ various methods to prevent bird strikes. These include firing pyrotechnics and air cannons, altering the landscape, and using speakers to play bird-of-prey and distress calls that deter nesting birds. Some airports also use more creative approaches, such as deploying pigs to eat gull eggs or using border collies to chase away herons and egrets.

Bird strikes on planes
Birds and aircraft share the same airspace, and the risk of collision with birds is a serious issue that airports and air transportation agencies have been addressing for some time. Bird strikes on planes have resulted in several notable incidents in recent years, including a United Airlines flight bound for Denver that was forced to return to Fargo, North Dakota, after a bird hit the front of the plane. Another flight, this time in the Shetland Islands of Scotland, struck a bird and had to return to the airport, leaving passengers stranded for the night.
Bird strikes can cause significant damage to aircraft, especially during take-off when the plane is at a low altitude where birds are more commonly found. The majority of bird strikes occur during take-off and landing, with only a small percentage happening mid-flight. The most frequently damaged components of civil aircraft in the USA are the wings and engines, each accounting for 25% of all damaged components from 1990 to 2023. Engines are particularly vulnerable to bird strikes, and while they are designed to withstand smaller bird strikes, ingesting a bird can cause a cascading failure, with the bird striking a fan blade, which is then displaced into another blade, causing a chain reaction.
To prevent bird strikes, airports employ various methods, from simple to creative. Some common strategies include firing air cannons, altering the landscape to be less bird-friendly, and using pyrotechnics and speakers to play bird-of-prey and distress calls to deter nesting birds. Airports also work with wildlife experts to identify, track, and safely trap and relocate birds. In some cases, airports may deploy dogs or falcons to chase away birds or use LED screens with googly eye graphics to scare them away.
Pilots also play a crucial role in bird strike prevention. They are advised to climb above 3,000 feet as quickly as possible when operating in areas with bird flocks and to slow down their aircraft when confronted with birds. Additionally, pilots should be vigilant and report wildlife sightings to airport operations teams.

Bird removal services
Birds in airports can cause damage to vehicles, harass travellers, and even cause safety issues. Bird strikes on planes have caused several incidents, including a United flight bound for Denver that was forced to return to Fargo, North Dakota, after a bird hit the plane. While plane engines are designed to withstand smaller bird strikes, bird strike prevention is a priority for airports.
Additionally, airports employ various strategies to deter birds from loitering in the vicinity. These include firing pyrotechnics, using speakers to play bird-of-prey and distress calls, and deploying animals such as pigs and border collies to deter specific bird species. Some airports also utilise advanced technology, such as radar systems, to monitor bird activity and take preventive measures.
In certain cases, airports may opt for humane traps to catch and release birds that find their way into terminals. This approach ensures the safe removal of birds without causing them harm. It is important to note that bird removal services play a vital role in maintaining a safe airport environment while also protecting the well-being of the birds themselves.

Bird-friendly landscape alterations
Bird strikes on planes can cause accidents and hundreds of millions of dollars in damage across the United States each year. Airports are required by law to continuously evaluate bird hazards and adopt measures to minimise the likelihood of collisions between wildlife and aircraft. Airports have come up with many creative ways to reduce bird hazards, including altering the nearby landscape to be less bird-friendly. Here are some examples of bird-friendly landscape alterations:
- Filling in ponds or other bodies of water: Water is an important factor in attracting birds to airports, especially coastal airports, which often have a much higher level of bird activity than inland airports. Even water pooling on uneven pavements can be enough to attract birds. Therefore, removing water sources can help reduce the number of birds in the area.
- Replacing grass with gravel: Grass, along with trees and shrubs, provides food and roosting sites for birds. By removing grass and other vegetation, airports can make the area less appealing to birds.
- Using firecrackers and pyrotechnics: Airports can use firecrackers, also known as pyrotechnics, to create loud noises that startle and scare birds away.
- Deploying pigs and border collies: In some cases, animals can be used to help reduce the bird population in an area. For example, Salt Lake City International Airport deploys pigs to eat gull eggs, while border collies chase away herons and egrets at Southwest Florida International Airport in Fort Myers.
- Installing LED screens with googly eyes: France's Lourdes-Tarbes-Pyrénées airport uses LED screens with googly eye graphics to scare off raptors loitering in the area.
- Implementing advanced radar systems: Airports can invest in advanced radar technology to detect and monitor bird activity in and around the airport. This allows air traffic controllers to make informed decisions, such as activating air cannons or timing arrivals and departures to avoid large flocks.
- Employing bird-scaring technology: Airports can experiment with various bird-scaring technologies, such as machines that circulate air scented with aromas that repel birds. For example, it is known that pigeons dislike the smell of grapes.
While some of these methods may be effective in the short term, it is important to note that encouraging wildlife at airports is a tricky business. Airports must continuously evaluate the effectiveness of their bird hazard management strategies and be prepared to adapt and implement new approaches as needed.

Bird-safe lighting and building design
Airports employ a variety of methods to prevent bird strikes, which can cause significant damage to aircraft and endanger passengers and staff. Bird strikes on planes have resulted in aircraft returning to airports and, in some cases, emergency landings. While plane engines are designed to withstand smaller bird strikes, bird strike prevention is a priority for airports worldwide.
One method to prevent bird strikes is to make the airport a less attractive habitat for birds. This can include filling in ponds, replacing grass with gravel, and removing vegetation and water features that may attract birds. Airports also use loud noises, such as pyrotechnics and air cannons, to scare birds away.
Another approach is to use technology to detect and deter birds. Radar systems can track bird activity and provide critical data to help airports mitigate the risk of bird strikes. MAX, for example, provides real-time tracking of bird activity and allows operators to analyse patterns and adapt their wildlife policies. Lasers can also be used as a silent and less disruptive way to deter birds. The beams are perceived as physical objects by birds, which they naturally avoid.
In addition to these methods, airports can also implement bird-safe lighting and building design practices to minimise the risk of bird strikes and reduce harm to birds. Bird-friendly building design is integral to the "green" sustainable building movement, and architects and design professionals have responded to the growing call for bird-safe solutions. Here are some strategies for bird-safe lighting and building design:
- Bird-friendly glass: Using fritted glass (with tiny ceramic dots) or frosted, ultraviolet, or low-reflective glass can make the glass visible to birds and reduce collisions. The Jacob K. Javits Convention Center in New York City renovated its building with fritted glass, reducing bird collisions by up to 90%.
- External screens and architectural features: Adding external screens, awnings, and overhangs can help eliminate reflections that may attract or confuse birds.
- Vegetation and landscaping: Strategically placing vegetation can minimise reflections and provide proper channeling to direct birds away from buildings.
- Reducing glass usage: Using less outside glass can reduce the need for mitigating design features.
- Lighting considerations: Reducing or eliminating up-lighting and spotlights can make a building less attractive to birds. Additionally, light pollution at night can disrupt the magnetic senses used by birds for navigation during migration.
- Building height and location: Bird-friendly building design ordinances often focus on new developments in locations near large open spaces, water features, or habitats that tend to attract more birds.
- Bird-safe materials: In addition to glass, bird-safe materials can be used uniformly on a significant portion of facades to make buildings safer for birds.
- Fragmentation and opaqueness: Altering glass design to include greater fragmentation and opaqueness can reduce bird collisions.
