Animal migrations are among the most spectacular natural phenomena on Earth, and they generate an estimated $18.6 billion in global tourism revenue annually. From the Serengeti’s wildebeest crossing to Alaska’s salmon runs to the humpback whale highways of the Pacific, migratory species are the foundation of some of the world’s highest-value nature tourism experiences.
The Migration Tourism Economy
The economic geography of migration tourism is distinctive. Unlike resident wildlife tourism, which concentrates economic benefits in a small number of protected areas, migratory species create economic corridors that distribute tourism benefits across multiple regions, countries, and continents.
The gray whale migration along the Pacific coast of North America generates tourism revenue in Mexico (breeding lagoons), California (passing points), Oregon and Washington (feeding areas), and Alaska (summer range). A single species’ annual journey supports tourism economies spanning 12,000 kilometers.
Birdwatching: The Largest Wildlife Tourism Segment
Birdwatching is the largest single segment of wildlife-based tourism globally, with an estimated 80 million active birdwatchers generating approximately $42 billion in annual expenditure worldwide. Migratory bird flyways are the backbone of this industry.
The East Atlantic Flyway connecting Arctic breeding grounds with West African wintering areas supports birdwatching economies across Scandinavia, the Netherlands, the United Kingdom, Portugal, and Senegal. The East Asian-Australasian Flyway supports birding tourism in South Korea, Japan, Australia, and New Zealand.
Key migratory bird hotspots — Doñana in Spain, the Wadden Sea in the Netherlands, Point Pelee in Canada — have become pilgrimage destinations for serious birders, generating concentrated economic impacts in otherwise modest tourism economies.
Threats to Migratory Species
The Convention on the Conservation of Migratory Species of Wild Animals (CMS) reports that 44% of migratory species are experiencing population declines. The primary threats are habitat loss along migration routes, climate-driven timing mismatches between migration and food availability, and direct mortality from infrastructure (wind turbines, power lines, shipping traffic).
For tourism, these declines translate directly to reduced encounter rates and degraded visitor experiences. Destinations that once guaranteed whale sightings or mass bird concentrations are experiencing declining reliability, which erodes their tourism proposition.
Conservation of Connectivity
Protecting migratory species requires protecting entire routes, not just individual habitats. This demands international cooperation at a scale that exceeds most existing conservation frameworks. The CMS Central Asian Flyway Agreement and the East Asian-Australasian Flyway Partnership represent attempts to coordinate conservation across multiple nations.
Tourism revenue creates powerful incentives for this cooperation. When governments can quantify the tourism revenue generated by migratory species passing through their territory, the economic case for conservation cooperation becomes self-evident.
Outlook
Migration tourism will remain one of the highest-value segments of nature-based tourism, but the industry must contend with declining species populations and shifting migration patterns driven by climate change. Investment in flyway conservation, habitat restoration along migratory corridors, and adaptive tourism planning will be essential to sustaining the $18.6 billion migration tourism economy.
