Conservation Efforts to Protect Coastal Bird Species

We’ve all been there; you’re sitting on the beach, enjoying a nice picnic, when a seagull swoops in and steals your fries, your sandwich, or your whole bag of Doritos. Many of us see coastal birds like gulls as a nuisance, little more than up-jumped pigeons with a bit more bravery. What people don’t understand is that coastal bird species, such as shorebirds, seabirds, and waterfowl, are some of the most charismatic and ecologically important birds on the planet.

These bird species don’t just live on the outskirts of our beaches. They also inhabit coastal wetlands, estuaries, and islands all over the world. Despite their sometimes aggravating nature, these animals play key roles in their respective ecosystems, including controlling insect populations, spreading seeds, and serving as prey for larger predators.

Unfortunately, like so many plants and animals that dwell on this Earth, coastal birds face numerous threats from human activities. Habitat loss, climate change, pollution, and disturbance from recreational and commercial activities are all having a profoundly negative effect on these animals, and are driving many of them towards extinction.

In this article, we will explore the challenges facing several coastal bird species. At the same time, we will highlight the importance of conserving their habitats, and the various conservation efforts currently in place to do so. As we conclude, we will also highlight the role of communities, governments, and conservation organizations in ensuring the future survival of coastal bird populations.

The Importance of Coastal Birds in Ecosystems

Coastal birds are an integral part of healthy coastal ecosystems. Their diverse range of habitats—from sandy beaches and tidal flats to salt marshes and mangrove swamps—are home to a wide variety of species. Thus, these animals serve important ecological functions in their respective niches. As with most animal subspecies, coastal birds can be categorized into different groups, each with its own unique behavior and role within the ecosystem.

Shorebirds

Some readers may be familiar with the plight of shorebirds, such as sandpipers, plovers, and willets. These birds can usually be found foraging along the shoreline and mudflats for small invertebrates, like crustaceans and mollusks. As a result, these little fellas are a crucial part of controlling the populations of these organisms. In the course of doing so, shorebirds like these also help aerate the soil, promoting nutrient cycling and maintaining a healthy ecosystem.

Seabirds

Seabirds, including our wonderful friends, the seagulls, spend much of their lives in the open ocean, or pelagic zone. The rest of the time they spend on the shore, terrorizing patrons on beaches and boardwalks. Their relatives include terns and albatrosses, and nearly all of these species are highly migratory. This means that these birds can travel thousands of miles between breeding and feeding grounds. Some of these nesting colonies can be found on cliffs or remote islands, which helps to support entire ecosystems that benefit from their presence. In addition, seabirds often act as apex predators in their respective ecosystems, regulating the populations of fish and other marine organisms.

Waterfowl

Other familiar coastal birds include waterfowl, such as ducks, geese, and swans. These birds often inhabit the estuaries, marshes, and coastal lakes near many homes. They also do quite well in either fresh or saltwater environments. They are highly adaptable, migratory creatures and play an important role in nutrient cycling by grazing on aquatic plants and invertebrates.

The loss of any or all of these coastal bird species would have cascading effects on the health of their respective ecosystems. Not only would such an event disrupt the delicate balance between plant and animal species in their habitats, it would affect our lives as their human neighbors as well.

Threats to Coastal Birds

Coastal birds are threatened by a number of manmade dangers. Numerous threats from human activities such as habitat destruction, climate change, and pollution have led to steep declines in various populations. The alteration or destruction of these habitats is immensely problematic and can cause huge problems in and around coastal settlements.

Habitat Loss and Degradation

One of the most significant threats to coastal birds is loss of habitat. Birds rely on these habitats for nesting, feeding, and migration. This is almost always caused by coastal development. Expanding cities, resorts, and industries are ever-encroaching upon important coastal habitats, and many such places have been drained or paved over in recent years. Ports, roads, and vacation spots are just a few of the human contrivances that precipitate the wanton destruction of wetlands, salt marshes, dunes, and beaches.

In addition to human development, changes in land use have had similar effects. The implementation of agriculture and livestock grazing can also degrade the quality of coastal habitats, causing soil compaction, erosion, and nutrient runoff; both of which negatively impact the health of coastal ecosystems and the species that live there.

Climate Change

Climate change is a major cause of many of Earth’s ecological problems. Climate change causes swift and deadly shifts in temperature, sea level rise, as well as storm severity and frequency. Rising sea levels threaten can flood important coastal habitats like beaches, salt marshes, and wetlands. This then eliminates these coastal places as a place for shorebirds to nest.

Extreme weather events, such as hurricanes, floods, and droughts, can cause permanent damage to nesting sites. These dramatic weather events can also reduce food availability, and cause the displacement of a number of native species, including coastal birds. The distribution and abundance of prey species can also be affected by climate change, and such alterations may force coastal birds to travel longer distances in order to find food.

Pollution

Pollution and litter have been a problem for native birds since the first piece of plastic trash came off a conveyor belt. Plastic waste and oil spills are two major major threats created by the industrial age. Plastic debris in the ocean can entangle coastal birds or be ingested accidentally, leading to injury or death.

Oil spills coat a bird’s feathers in sticky, glistening oil, thereby impairing the animal’s ability to fly. Oil can also prevent a bird from regulating its body temperature, which can also be fatal. When coastal areas are often exposed to agricultural runoff or other harmful pesticides, fertilizers, and chemicals, the result is reproductive defects, poisoning, and death. Often times, one bad batch of chemicals can destroy an entire population within a given coastal zone.

Disturbance from Human Activities

We joked and complained earlier about the presence of seagulls on “our beaches” but the truth is, the birds were there first. Beach use, boating, and construction can disturb nesting birds and other coastal avians. Shorebirds, in particular, are sensitive to human presence during their breeding season and one little disturbance can cause them to abandon their nests entirely, leading to reduced reproductive success.

In addition, commercial activities such as fishing, shipping, and tourism can cause habitat degradation, pollution, and direct harm to seabirds, who might be crushed, entangled, accidentally captured, or exposed to any number of hazardous materials.

Invasive Species

Over the years, many an invasive species had caused entire populations of birds to go extinct. From the Dodo bird to the Hawaiian Kauaʻi ʻōʻō, many animals have lost their eggs, land, and lives to our cuddly pets and farm animals. Mammals like rats, cats, pigs, and foxes, pose a significant threat to coastal bird populations and always have. Invasive plant species are equally culpable, however, and these transplants can also alter coastal habitats, making them unsuitable for native bird species.

Conservation Efforts to Protect Coastal Bird Species

Fortunately for the birds, many humans recognize the growing threats to coastal bird species. Many governments, conservation organizations, scientists, and local communities have launched various initiatives to protect and restore the ecosystems that these birds call home. The goal of these initiatives is multi-faceted. They aim to safeguard nesting sites and generally mitigate the impacts of human activities. Some of the most effective conservation strategies included in this section are: habitat restoration, legal protections, community engagement, and education.

Habitat Restoration and Conservation Areas

One of the most important conservation efforts for protecting coastal birds is to help restore their natural habitats. Many of these restoration projects aim to rehabilitate degraded ecosystems, thereby reestablishing the conditions that coastal birds need to thrive. These efforts have been mostly successful, but obviously more work is needed to replant needed vegetation, restore tidal flow to draining wetlands, and create buffer zones around critical nesting areas.

National parks, wildlife reserves, and marine protected areas are also doing their part to help give these birds a safe place to live. These places are essential to safeguarding coastal bird populations and many of them are specifically designed to host only a certain population of birds. In many cases, these places vastly limit human activities within their borders, offering coastal birds the opportunity to nest, feed, and migrate without having to contend with disturbances or human interference.

Legal Protections and International Agreements

Governments don’t always help out, but sometimes they can step up and play a vital role in protecting coastal bird species. Through legal frameworks and regulations such as the Migratory Bird Treaty Act, many birds have found protection and peace. The MBTA, for example, offers protection to migratory birds, specifically, by making it illegal for humans to harm or disturb them in any way.

Certain international agreements, such as the Ramsar Convention (which focuses on wetland conservation) and the Convention on Migratory Species (CMS), also play a critical role in coastal bird protections. Such agreements facilitate international cooperation to protect birds that travel across international borders.

Community Involvement and Education

Community involvement is another essential piece of successful conservation efforts. Local communities that live near coastal areas are often involved in the advocation and implementation of environmentally friendly policies. Such policies include reducing disturbances and participating in habitat restoration efforts, like beach or wetland clean-up events.

It’s also important to keep folks educated about the importance of conservation. By raising awareness about the importance of coastal birds and the threats they face, the world at large can become stewards of their fate. Human beings can be more mindful about their plastic trash, chemical waste, and where they set their feet when walking down to the beach. It doesn’t take a lot of effort, but it makes a lot of difference.

Monitoring and Research

Conservationists often rely on monitoring and research to help track the health of coastal bird populations. By keeping an eye on things, these educated, altruistic people can more properly assess the effectiveness of certain conservation strategies. Research also helps to identify the specific needs of different bird species. We can learn what they like to eat, where and how they migrate, and where they land to breed and nest. This all equates to an invaluable amount of data that can be used to inform and improve upon existing conservation efforts.

Artificial Nesting Structures

In some cases, artificial nesting structures may be needed. Things like floating islands or man-made sand dunes are often used to provide or replace safe nesting for coastal bird species to lay and raise their young. These artificial habitats have been highly successful in providing crucial space for birds where natural sites are no longer available.

True Investigator Says…

Coastal bird may be annoying at time (we’re looking at you swans and seagulls) but these animals are essential to maintaining the health of our shared coastal ecosystems. Even today, these birds face significant threats from human interaction. They have to contend with habitat loss, climate change, pollution, and the proliferation of human agriculture and the resort industry.

Nevertheless, conservation efforts, including habitat restoration, legal protections, and community engagement, have become crucial to ensuring their survival. The truth is, we need to protect these birds and their ecosystems, because it’s good for everyone. By protecting coastal birds, we can fully help to safeguard the biodiversity of these important coastal habitats. This is especially pertinent in the modern day, when conservation can be the difference between a brighter tomorrow and a bleak and lifeless dystopian future.
