Wildlife on the Marsh

Wildlife Viewing

The Horicon Marsh has been named a “Wetland of International Importance” by the Ramsar Convention of the United Nations. The marsh supports more than 300 species of birds and numerous other wildlife species.

Help keep these species alive by learning more about the wildlife and their habitat! Visit the WI DNR's webpage to learn about invasive species and what you can do to help or download the WI DNR's field guide to invasive plants!



Year-round, birdwatchers flock to the Horicon Marsh to enjoy some of the best birds in North America.

Horicon Marsh is one of North America’s most important habitats for migrating Canada geese. The spring and fall migrations draw thousands of birdwatchers to the marsh. 

Horicon, Wi is a proud Bird City for OVER 6 years now!
