For example, the Common Yellowthroat—a cheery warbler you might find hanging out by cattail patches—is widespread throughout North America, but has undoubtedly declined in many regions with the draining of marshes and threat of light pollution.
The Common Yellowthroat’s species migration map.
Our new study suggests that the post-breeding, southbound migration season (i.e. “fall migration” for the Northern Hemisphere) is the most dangerous time of year for warblers like the Common Yellowthroat. In their Species Conservation Challenges maps, you can see exactly when and where Common Yellowthroats are exposed to certain human activities and environmental changes.
Knowing when and where migratory birds face their biggest obstacles helps us better understand the challenges they face and explore solutions that benefit birds and people. Become a Bird Migration Explorer and learn more about your favorite birds! |
