In the video above, pack creators Susie Ibarra and Jake Landau break down the importance of capturing the sounds of millions of birds that use the African-Eurasian Flyway each year who's routes, food availability, and thousand year long routines are being drastically altered due to Climate Change. The duo interview biologists and bird experts to give the Splice users a glimpse of where these fascinating sounds came from and the lengths that were taken to capture them.

How Climate Change is Disrupting Bird Migration in Europe and Africa
Bird migration is one of nature’s most spectacular events, with millions of birds traveling between Europe and Africa each year, following ancient routes for breeding and survival. However, climate change is increasingly disrupting these migration patterns, threatening bird populations and ecosystems.
Changing Seasons, Changing Routes
One of the most significant impacts of climate change is the shifting of seasons. Rising global temperatures are causing earlier springs and later autumns, which means that birds arriving at their breeding grounds in Europe often find that the timing of food availability—such as insect hatches—has changed. This mismatch affects species like the Barn Swallow (Hirundo rustica) and Pied Flycatcher (Ficedula hypoleuca), which rely on abundant food sources to raise their young.
Additionally, warming temperatures are altering traditional migratory routes. Some birds are shortening their migrations, staying in Europe instead of flying to Africa for the winter, while others are being forced to travel farther north in search of suitable climates.

Droughts and Habitat Loss in Africa
For many migratory birds, Africa serves as a critical wintering ground. However, increasing desertification, deforestation, and prolonged droughts—especially in the Sahel region—are making survival harder. Species like the European Turtle Dove (Streptopelia turtur), which winters in West Africa, are facing declining populations due to habitat degradation and food scarcity.
Extreme Weather Events
Storms, heatwaves, and unpredictable weather patterns—intensified by climate change—are increasing mortality rates during migration. Birds like the common swift (Apus apus), which rely on stable wind patterns, struggle with stronger storms and headwinds, making their long-distance journeys even more perilous.
What Can Be Done?
Conservation efforts, such as protecting key wetlands, forests, and stopover sites, are essential to supporting migratory birds. International cooperation between Europe and Africa is also crucial to ensure that birds have safe passage throughout their migration. Additionally, tackling climate change through reduced carbon emissions and habitat restoration can help protect these incredible species.
Bird migration is a delicate balance of nature, and as the climate continues to shift, we must act now to ensure these journeys can continue for generations to come.
