The Wisconsin Department of Natural Resources (DNR) encourages Wisconsinites to enjoy the return of migratory birds to Wisconsin this spring and take a few simple steps to help our feathered friends.

The Mississippi River flyway and Great Lakes shorelines make Wisconsin an important place for more than 350 species of birds during spring migration. In addition, our state's diverse grasslands, marshes and forests provide key habitats for migratory birds.

“Spring migration brings hope and excitement for birdwatchers,” said Ryan Brady, Wisconsin DNR conservation biologist. “But it’s also a dangerous time for birds, many of which need our help.”

Warblers, orioles, thrushes, hummingbirds, tanagers, indigo buntings and shorebirds are among the favorite long-distance migratory birds that people will likely see in the upcoming weeks. Their migration is influenced primarily by changes in the duration of daylight.

Give birds a hand

Native bird populations in the U.S. and Canada have declined by nearly 3 billion birds since 1970.

The public can help birds during this key time by taking a few small steps at home:

• Shut off exterior lights at night during May, which is historically peak migration.
• Reduce window collisions with external screens, markers or cords. Get DIY solutions from SOS Save Our Songbirds.
• Visit the Wisconsin DNR’s listings of native plant sales and nurseries so you can add native plants to your landscaping. Fruit-bearing native trees like serviceberry, dogwood and cherry, provide both food and cover for birds.
• Avoid pesticides to help insect-eating birds, which include many backyard species as well as swallows, swifts, nightjars and flycatchers.
•  

Try bird watching

The DNR’s Birding and Bird Conservation webpage contains links to birding hot spots and organizations that often provide guided bird outings. Celebrate birds and connect with your community with events including:

• Madison Bird and Nature Adventures, April 26
• Oshkosh Bird Fest, May 2
• Horicon Marsh Bird Festival, May 8-10
• Brew City Bird Festival, May 9-18
• Chequamegon Bay Birding & Nature Festival, May 21-23
• Door County Festival of Nature, May 21-24

Natural Resources Foundation 15th Annual Birdathon

The Great Wisconsin Birdathon will take place from April 15 to June 15. This event is Wisconsin’s largest fundraiser for bird conservation and is hosted by the Natural Resources Foundation of Wisconsin, a nonprofit that protects our state’s lands, waters and wildlife and connects all people with nature.

Bird enthusiasts from across the state form teams each year to find as many bird species as possible while raising critical conservation funds. Similar to a walkathon fundraiser, participants record bird sightings for pledges instead of miles logged.

Individuals or teams can participate any time from April 15 to June 15, and all skill levels are welcome. While many participants choose to compete over 24 hours, teams also can opt to bird for a weekend, a week or even the whole 60-day event.

Teams can bird anywhere in Wisconsin — a state or local park, wooded areas or even in their backyard. Anywhere you can see birds, you can participate.

The money raised by the Birdathon supports the Natural Resources Foundation’s Bird Protection Fund, which provides financial backing for projects around Wisconsin that protect bird habitats, support avian research and monitoring efforts, and promote education and outreach. In 2025, the Birdathon raised $127,000 for bird conservation. Each year after the event concludes, the Bird Protection Fund Committee — composed of Wisconsin bird conservation experts, including DNR staff — helps determine where the funds will positively impact the state’s birds and allocates funding accordingly.

Visit the Great Wisconsin Birdathon webpage to register, make a pledge or learn more.
