Mid-September is a great time to be birding at the Complex.

The Montezuma Wetlands Complex is a globally-significant Important Bird Area and supports a million or more waterfowl of at least 30 species, thousands of inland migrating shorebirds, a myriad of ‘confusing’ fall warblers and many rare and endangered species.

The 242-square mile Montezuma Focus Area, which was highlighted under the North American Waterfowl Management Plan as critical migratory bird habitat, serves as the boundary for the Muckrace.

What is the Muckrace?

Teams bird together from 7:00 PM Friday until 7:00 PM Saturday, trying to locate as many bird species as possible. Winning teams over the past several years have identified as many as 148 species, and collectively, as many as 192 species have been seen by the 15 to 28 teams, in a single day

In the 20-year Muckrace history, over $125,000 has been donated in support of bird habitat restoration, research or public access.  Recent projects have included: a touch screen display at the Montezuma Audubon Center highlighting habitat restoration, removal of invasive plants and replacement with wildflowers for pollinators at the Refuge Visitor Center, improvement of water level management on a 448-acre impoundment, construction of the Deep Muck observation deck, and support for American Black Duck winter banding.
