Researchers have discovered that despite the challenges faced by Lapland terns during their nesting season, these birds have adapted to climate change in remarkable ways. The Lapland tern embarks on a spring migration from Antarctic waters in March-April, stopping to refuel with small fish and crustaceans along the way. By studying the migration patterns and food sources of these birds, researchers can gain valuable insights into how they are adapting to environmental changes.
Despite projected increases in carbon dioxide emissions by 2100, the Lapland terns nesting in Sweden, Iceland, and Greenland are not significantly impacted. In fact, researchers have found that even with changing climate conditions, these birds are able to adapt if the loss of food is not severe. During their autumn migration towards the south, the Lapland terns dine in nutrient-rich areas on their journey through the southwest coast of Africa and the waters of the Indian Ocean.
While headwinds may become stronger in the future, the Lapland terns have adapted their migration patterns to navigate these changes. In Antarctica, where they fish for krill crustaceans, researchers have found that there is still enough krill for them to feed on even as ice levels decrease drastically. This resilience and adaptability make it clear that these birds are able to thrive in changing environments.
