Fall in Love with Migration This World Migratory Bird Day

From apple picking to leaf peeping, fall brings a flurry of festive activities. Need to pinpoint the perfect day for some fall birding? Take out the guesswork with the Bird Migration Explorer!
The routes birds follow between their nesting and wintering grounds are as varied as the birds themselves. Discover the best days to find migratory birds like the Blackpoll Warbler with the Bird Migration Explorer’s state-of-the-art Species Maps! Start from the Blackpoll Warbler Migration Map, then zoom in and follow the weekly time bar below to see when they may be passing through your area. The larger the circles, the more likely you’ll spot this iconic warbler near you.

These maps combine the best available migration data and community science contributions to create highly accurate maps showing the routes and abundance of hundreds of bird species throughout their entire yearly migration cycle.

The Bird Migration Explorer does more than just forecast where your favorite birds will be—it tells you what challenges they face along their migratory journeys, too! Our recent 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. With the Bird Migration Explorer’s Species Conservation Challenges maps, you can discover where, when, and how birds like the Blackpoll Warbler are affected by human activities and environmental changes throughout the year.

But once you find them, identifying fall birds can be its own unique challenge! After breeding season, birds lose their vibrant mating plumage and become much harder to identify. Check out this helpful primer full of visual cues and behaviors to look for among drab, quiet autumn migrants. Hurry! Fall migration is in full swing, so get out there and start birding.
