The Bird Migration Atlas

The European Turtle Dove is a relatively small bird, weighing only about 100 grams (3.5 ounces). Despite its size, the European Turtle Dove undertakes an incredible long-distance migration of around 5,000 kilometers (3,000 miles) from Europe to sub-Saharan Africa every year. This remarkable journey, along with the migratory routes of hundreds of other bird species, can be explored in detail on the Bird Migration Atlas.

The Bird Migration Atlas is an interactive map that plots the migration patterns of over 300 bird species across two continents: Eurasia and Africa. The map integrates data from historical European ringing schemes and modern tracking technologies to provide a comprehensive view of migration routes across both continents.

The Overall Connectivity map serves as the starting point for all species, revealing patterns of migratory connectivity. It highlights how birds from different geographic regions move, considering variations by age and sex. This map visualizes broad migratory trends, such as seasonal routes and key stopover sites that birds use during their journeys. Users can toggle additional layers for a more nuanced view, such as tracking data (where available), to better understand the specific migratory routes of individual species.

The By Region map allows for a deeper examination of bird movements based on where they were originally ringed and where they have been recovered. By color-coding encounters according to European ringing regions, this tool makes it easier to trace how individuals from specific populations migrate. The inclusion of tracking data (from sources like Movebank) further enriches the visual representation by displaying precise movement patterns, such as those derived from satellite transmitters or geolocators.

You can explore the migration patterns of American bird species on the impressive Bird Migration Explorer. The Bird Migration Explorer is an interactive map that visualizes the migratory patterns of 458 bird species that breed in the United States and Canada. Using the map, you can explore the journeys of individual bird species and discover when different species are likely to migrate through your town or city.

The Bird Migration Explorer allows you to view animated maps showing the full migration routes of these 458 species. By entering a location into the interactive map, you can also discover which bird species migrate to or through that location and when they are most likely to be seen.
