What’s New

There are now over 11,500 bird tracks for almost 200 species including new tagging data from the Bird Genoscape Project, Motus Wildlife Tracking System, USGS Bird Banding Lab, and Movebank; and updated weekly abundance using the latest models by eBird at The Cornell Lab
The redesigned Locations sidebar shows tagged species for your primary location, and you can filter the map to see bird connections from different types of tracking devices
On Species Conservation Challenge pages, the conservation challenge selection box includes graphs to facilitate comparison of exposure across challenges
North American population size estimates for landbirds are now available in the Conservation Statistics section of Species pages
Species Migration animated maps load faster and show the footprint of tracked birds upon opening
In partnership with Movebank, we launched the Migratory Bird Initiative Collection, a compilation of bird migration studies shared by collaborating researchers
