Airports provide birds with food, water, and shelter
Birds are attracted to airports because they provide them with food, water, and shelter. Airports are vast, open spaces with a full environment, and the attractiveness of vegetation is a balance between food presence, accessibility, and protection against predators. Airports often have turfgrasses planted alongside runways and taxiways, which birds like Canada geese feed on. The bustle of the airport discourages large predators, giving birds a safer sanctuary.
The occurrence of birds at the airport depends on the attractiveness of the neighbouring habitats. Many airports are located near wetlands or drainage ponds, which act as superb noise dampeners and attract migratory waterfowl, gulls, and other large birds. These areas provide good breeding grounds for birds, and as a result, birds view the airports as safe places for resting, gathering in flocks, or hiding from predators.
To prevent bird strikes, airports have implemented various methods to deter birds. Passive methods include structural solutions and barriers that reduce the attractiveness of the airport infrastructure to birds, such as modifying or removing shelter habitats like old hangars and forested areas. Active methods include deploying pigs to eat up gull eggs, using border collies to chase away herons and egrets, and employing falconry to discourage dunlins and other migratory shorebirds. Airports also use pyrotechnics, sirens, air cannons, and LED screens with googly eye graphics to scare birds away.
While airports work to minimise bird strikes, the presence of birds at airports is a constant challenge. The balance between providing an attractive ecosystem for birds and ensuring the safety of aircraft operations is a delicate one. As such, airports must continually adapt and employ innovative solutions to create a hostile atmosphere that discourages birds from considering airports as sanctuaries.

Airports are often located near water, attracting migratory birds
Airports are often located near water, which attracts migratory birds. Airports are typically built on flat, open spaces with few trees, making them ideal locations for birds to rest, gather in flocks, and hide from predators. The bustle of an airport can also drive away large predators, making it a safer option for birds.
Additionally, the presence of water, which is a superb noise dampener, makes these areas even more attractive to migratory waterfowl, gulls, and other large birds. The availability of water for drinking and bathing is another draw for birds. As a result, airports located near substantial wetlands or drainage ponds may experience a higher volume of bird activity.
The occurrence of birds at the airport also depends on the attractiveness of the neighbouring habitats. For example, Vancouver's airport is located on a major Pacific flyway and has parks and wildlife conservation areas nearby, making it a popular resting spot for birds. Similarly, Seattle-Tacoma International Airport is situated in a major bird migratory region, making it prone to bird activity.
The presence of birds near airports can lead to bird strikes, which are a significant concern for aviation safety. Airports employ various methods to prevent bird strikes, including habitat management, pyrotechnics, sirens, border collies, falconry, and even pigs to eat gull eggs. Some airports also use realistic owl figurines or circulate air scented with aromas that repel birds.

Airports are quiet, with few predators, making them a safe sanctuary
Birds are attracted to airports because they provide a safe sanctuary. Airports are often located near wetlands, drainage ponds, or coastlines, which provide ample water for drinking and bathing, as well as good breeding grounds for certain bird species. The vast open spaces of airports offer ideal resting and gathering places for birds, away from predators. The bustle of airport activities can also deter larger predators, making it a safer option for birds.
The presence of food is another factor that attracts birds to airports. Some bird species feed on turfgrasses planted alongside runways and taxiways, while others may find food in the surrounding habitats. Airports with parks and wildlife conservation areas nearby can be particularly enticing rest areas for birds.
To mitigate the risks of bird strikes, airports employ various strategies. Passive and active wildlife management techniques are commonly used, such as modifying the ecological character of the airport by removing water sources, food resources, and shelters. Structural solutions and barriers can also deter birds by reducing the attractiveness of the airport infrastructure.
Some airports use more creative approaches, such as deploying pigs to eat gull eggs, using border collies to chase away herons and egrets, or employing falconry to discourage migratory shorebirds. Other methods include firing air cannons, altering the landscape by filling in ponds or replacing grass with gravel, and using LED screens with googly eye graphics to scare off raptors.
While airports implement these measures to reduce bird strikes, it is important to recognize that birds are naturally drawn to the safe and resource-rich environment that airports unintentionally provide.

Airports have warm, paved surfaces, ideal for resting and hiding
Birds are attracted to airports because they provide a warm and safe environment for resting and hiding. Airports are often located near wetlands or drainage ponds, making them attractive to migratory waterfowl, gulls, and other large birds. The bustling activity of an airport can deter large predators, providing a sense of safety for smaller birds.
The warm, paved surfaces of taxiways and runways offer ideal resting spots for birds, especially during colder seasons. These areas provide ample space for birds to gather in flocks and socialise. The warmth of the surfaces may also be comforting for birds, particularly during colder months when natural warmth sources are less abundant.
The vast expanse of an airport, with its open spaces and infrastructure, offers numerous hiding spots for birds. They can perch on signs, fixtures, and buildings, or nestle in old hangars and forested areas within the airfield. Airports with nearby bodies of water provide additional attractions, as birds can use these areas for drinking, bathing, and breeding.
To mitigate the presence of birds, airports employ various strategies, including habitat management, pyrotechnics, sirens, and the use of trained dogs or birds of prey. Some airports modify the surrounding landscape by filling in ponds or replacing grass with gravel to make the area less inviting to birds. Others use LED screens with googly eye graphics to startle raptors, or machines that circulate bird-repelling scents.
While these measures aim to deter birds, it is important to recognise that airports can inadvertently provide attractive resting and hiding spots for our feathered friends. The balance between maintaining aviation safety and preserving wildlife is a delicate one, and airports are constantly refining their approaches to achieve this equilibrium.

Airports' vast, open spaces allow birds to gather in flocks
Birds are attracted to airports for various reasons, and one of the main reasons is that airports provide vast, open spaces for birds to gather in flocks. The open layout of airports offers an ideal setting for birds to congregate and socialise. The expansive runways and surrounding areas provide ample room for birds to assemble, especially for species that prefer wide-open spaces.
Additionally, the absence of significant vegetation or obstacles in these areas allows birds to move around freely and engage in various activities, such as foraging for food or performing courtship rituals. The open spaces also provide a sense of security, as birds can easily detect potential predators or hazards in their surroundings. This sense of safety is further enhanced by the perception that airports are sanctuaries, free from the threat of larger predators due to the constant human activity and noise.
Moreover, the open environment of airports can be particularly attractive to certain species of birds. For example, birds of prey, such as hawks and eagles, may utilise the open spaces for hunting or scouting for prey. The open layout provides them with a clear view of their surroundings, making it easier to spot potential meals. Similarly, migratory birds may use these open areas as resting spots during their long journeys, providing them with a sense of openness and freedom.
While the vast, open spaces of airports can be advantageous for birds, they also present challenges. The lack of cover or hiding places can make birds more vulnerable to predators or harsh weather conditions. Additionally, the open layout can increase the risk of bird strikes, as birds may collide with aircraft during take-off or landing. As a result, airports employ various methods to deter birds from gathering, such as using pyrotechnics, sirens, border collies, falconry, and even deploying pigs to eat gull eggs.
