About this bird migration map

Bird Migration Radar shows public bird observations from GBIF for a broad catalog of migratory species. The map highlights where observations cluster by month and year.

How to use it

• Start with all species and all months to see the full observation map.
• Filter by species to inspect a single migration pattern.
• Filter by month to compare spring, summer, fall, and winter observations.
• Use the record list to inspect recent observations and jump to their map locations.

Data notes

• Records come from GBIF observations with coordinates, dates, present status, and open Creative Commons licenses such as CC BY and CC0.
• Observation density reflects where people report birds as well as where birds occur.
• This map is useful for exploration and seasonal patterns, not for real-time radar tracking.
