Thousands of seabirds have recently washed ashore along Denmark’s coasts. Now, volunteers across the country are joining forces in a major effort to count and study the cause of the mass deaths.
Nationwide Count of Dead Seabirds
The sight of seabirds washed up on the beach has become increasingly common in Denmark, especially during winter. In late February, the Danish Ornithological Society (Dansk Ornitologisk Forening, DOF) will carry out a coordinated effort to count the many gannets and fulmars found lifeless along the Danish coastline.
The bird count, called SUPRE—short for “Seabirds Under Pressure”—takes place during the last weekend of February. It aims to gather data on how many birds arrive dead onshore and which species are most affected. This large-scale survey will cover numerous beach locations, particularly along the Jutland west coast and the Kattegat, where most dead seabirds tend to be found.
Why Seabird Deaths Are Increasing
In recent years, several mass deaths of seabirds have been recorded across the North Atlantic, including Denmark. According to experts, multiple factors appear to be putting severe pressure on marine bird populations. Changes in ocean temperatures driven by climate change have disrupted feeding patterns. Adding to the crisis, large amounts of plastic waste and discarded fishing gear float in the North Sea and surrounding waters.
While some birds die from starvation after struggling to find food, others perish when entangled in nets or exposed to oil and pollutants. Conservationists hope that the data from the SUPRE project will help clarify which threats are most critical.
The results could also complement wider marine protection efforts such as Denmark’s recent initiative that limits harmful fishing methods, outlined in Denmark’s ban on trawling.
Citizen Science in Action
The SUPRE project is financed by the Velux Foundation and supported by Aarhus University, where collected birds are sent for autopsy. More than three million seabirds are estimated to winter in Danish waters each year, so a complete picture requires nationwide participation.
Many of DOF’s volunteers will walk along beaches on February 28 and March 1, recording each find and taking photos for later analysis. A smaller team will continue collecting samples throughout the year.
Because of that, the count provides one of the most comprehensive snapshots of seabird mortality ever attempted in Denmark.
Understanding What Kills the Birds
Whenever a bird is found entangled in fishing lines or covered in oil, researchers can trace the cause of death more accurately. Knowing where and how these fatalities occur is vital to protecting marine ecosystems.
Even though most Danish fishers are strongly against pollution, experts hope that visible data on the problem can encourage the entire industry to adopt more environmentally responsible practices. Improved awareness may also influence how waste and fishing equipment are handled.
These findings connect to other environmental priorities such as marine conservation zones and insurance initiatives addressing coastal ecology, like those discussed in environmental protection in Denmark.
A Fragile Balance Along the Coast
Denmark’s western coastlines are some of the most biologically rich areas in Northern Europe. Yet they are increasingly under pressure from human activity and shifting weather patterns. The SUPRE project highlights how delicate this balance has become.
Without a doubt, the winter bird count represents a growing public interest in Danish wildlife and environmental accountability. By combining professional research with citizen participation, Denmark hopes to secure long-term data that can guide future conservation strategies.
As the results are compiled later this year, attention will turn to what can be done to prevent further losses. For now, the upcoming weekend of fieldwork will help shed light on a mystery stretching across the North Atlantic—a mystery involving climate change, pollution, and the fragile lives of seabirds drifting toward Danish shores.
