Union Slough National Wildlife Refuge

small state map showing location

Titonka, Iowa


Union Slough National Wildlife Refuge was established in 1937 for the production and management of waterfowl and other migratory birds in the Mississippi Flyway. Today, more than ever, we are dedicated to preserving its wildlands for wildlife.

The Refuge consists of 2,845 acres of marsh, grassland and timber. This biological diversity provides suitable habitat for over 240 species of birds. As you visit the refuge, keep in mind that, like all wild animals, each bird requires a certain habitat to survive. As one habitat blends into another, bird communities will change, just as seasons change.

White Pelicans, Great Blue Herons, Yellow Warblers, Brown Thrashers and Bobolinks are a few of the many birds that can be seen along the Wildlife Drive and the Deer Meadow Nature Trail. If you should find an interesting or unusual species, please let us know at the Refuge Headquarters. We will enjoy sharing this information with other visitors.
