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! Start Exploring 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.

[LAST CHANCE] Get your gift matched before World Migratory Bird Day ends

With so much at stake, we can and must do more while there’s still time.

Midnight Deadline: Make 2X the impact this World Migratory Bird Day! Chimney Swift. Tomorrow is World Migratory Bird Day—and if there was ever a time when birds needed the support of passionate people like you, it’s right now. The Chimney Swift, like one-third of all U.S. bird species, needs immediate conservation action. The latest State of the Birds report found that this aerial insectivore is at a crisis tipping point, having experienced long-term population losses and accelerated recent declines within the past decade. As these birds face severe habitat loss, food scarcity, and climate-driven disruptions, we must act now across entire flyways—before they reach a point of no return.  Start your annual donation before midnight tonight while your first gift can still be matched, up to $30,000. The steep declines of these migratory birds signal widespread breakdowns in ecosystem health, threatening coastal storm protection, urban biodiversity, and marine food webs. But there’s hope in action—and with more than 120 years of expertise under our wing, we know what it takes to protect beloved species like the Chimney Swift. Because of your support, we’re pairing cutting-edge tracking science with proven policy expertise to defend bedrock laws like the Migratory Bird Treaty Act and Endangered Species Act. It comes down to this: Where we work—and when you help—birds are better off.  But with so much at stake, we can and must do more while there’s still time. Please start your annual donation today to provide uninterrupted resources our teams can depend on to defend birds year after year. Remember: Your first gift could go 2X as far in honor of World Migratory Bird Day—but only until midnight tonight!
