The Mississippi River: A Hemispheric Crossroads The Mississippi River, also known as the “lifeblood of America,” is a globally significant ecosystem that supports nearly 60 percent of North America’s migratory bird species. This World Migratory Bird Day, discover all the birds the Mississippi River links, from Uruguay to Missouri. Keep Reading Just north of St. Louis, Missouri, the Audubon Center at Riverlands sits at one of the most important migratory stopover sites along the Mississippi River for birds flying between the Arctic, the Mississippi River basin, the Gulf, and beyond. And for species like the Prothonotary Warbler, the Mississippi River isn’t just a stop along the way—it’s where they nest and raise their young. This habitat is essential to their survival. Birds observed at our Riverlands Center link this floodplain to more than 45 countries and territories from northern Canada to the southern reaches of Chile and Argentina. Using the Bird Migration Explorer, can you find all the birds and countries connected through the Mississippi River? Start Exploring Prothonotary Warbler.

Watch Now: "Birds on the Move"

Celebrate World Migratory Bird Day with our new docuseries.

Trouble viewing this e-mail? Try our web version. Celebrating All Things Bird Migration Tonight, it’s forecasted that 365 million birds will be traveling north to their breeding grounds in the Boreal Forest; that means there’ll likely be more birds overhead than there are people in the United States! Bird migration is one of Earth’s greatest natural phenomena and our annual reminder of what’s at stake in what we do. So, on World Migratory Bird Day, we invite you to watch our Birds on the Move documentary series and join us for a journey of discovery, science, and shared wonder as millions of birds take flight, crossing oceans and continents on their epic migrations. Watch Birds on the Move on YouTube Our work—whether it’s restoring critical riverside habitat in the arid West or inspiring the next generation of environmentalists at one of our action centers—is grounded in conservation led by birds. Each year, billions of birds migrate across the Western Hemisphere, traveling thousands of miles along ancient flyways that connect continents, countries, and communities. Just look at the Lesser Yellowlegs, pictured above. It was tagged for the first time with a satellite transmitter by Audubon scientists in Cali, Colombia. It flew across the Atlantic in a single 50-hour flight and was just spotted in Vermillion Parish, Louisiana. (It’s also the star of the next episode of our documentary series.) Cutting-edge science and tracking technologies are uncovering these journeys in real time, powering a new, hemispheric approach to protecting birds. That's where you come in. Migration is about more than the journey; it’s about every place birds need along the way. Places you can protect and champion. Birds show us the health of the world. And so can you when you share their journey with your friends and family. Subscribe for the Next Stop Lesser Yellowlegs.

Match Deadline: Make double the difference ahead of World Migratory Bird Day

Make 2X the impact for birds and the places they call home.

Deadline approaching: Make twice the impact for the birds you love ahead of World Migratory Bird Day. Chimney Swift. This World Migratory Bird Day, we need your help to bring birds back from the tipping point The Chimney Swift was once abundant in our city skies. But today, they are facing steep population declines throughout most of their range, particularly around urban areas in the Upper Midwest, Gulf Coast, and southeastern Piedmont regions, as they lose the brick chimneys they rely on for roosting and nesting. Last year's State of the Birds report also named this beloved species—alongside 36 other birds—an Orange Alert “Tipping Point” species, having experienced long-term population losses and accelerated recent declines within the past decade. These birds can’t ask for your help. So, we’re asking for them: Will you start an annual donation ahead of World Migratory Bird Day to give birds the protection they need, not just today but tomorrow, too? Thanks to a group of generous donors, your first gift could be matched 2X, up to $20,000—but only until midnight tomorrow! With more than 120 years of expertise under our wing and dedicated friends like you by our side, we can create a safer future for birds and people. And truth be told, we already are. For example, Audubon’s Migratory Bird Initiative (MBI) is transforming our ability to work effectively across the hemisphere by combining the known movements of tracked birds to identify precisely where and when birds need the most help along their routes. Our comprehensive approach—combining science, advocacy, habitat restoration, and education—creates a powerful force against future extinctions. But there is more work to be done, so we’re asking for your steadfast support ahead of World Migratory Bird Day. Please be one of the caring bird lovers we’re counting on to start an annual donation before midnight tomorrow—and when you do, your first gift could be matched, up to $20,000.
