How to Use Migration Data
Real-Time Tracking
Check BirdCast live maps during migration season to see where birds are actively migrating at night, then plan your morning birding accordingly.
Seasonal Planning
Use eBird abundance maps to understand when target species typically arrive in Alaska. Plan tours around peak migration windows.
Track Species Routes
Explore Movebank and Audubon Explorer to see the actual flyways and stopover sites used by species that pass through Alaska.
Citizen Science
Contribute your own sightings to eBird or iNaturalist during your Alaska birding trip. Every observation helps researchers track migration.
