Welcome!
Anyone interested in birdwatching, nature, or the quality of the environment is welcome to become a member of the Dubuque Audubon Society.
Our tri-state region is a great place for birds, and one of the great things about birds is that you can enjoy them at all levels of involvement. You may be surprised how many different species we have in the area at different times of year and how quickly you can begin to identify many of them once you start looking. (Binoculars help!) Any time of year is a great time to be a birder, and we hope you’ll join us!
Our Mission
The mission of the Dubuque Audubon Society is to provide educational opportunities to the people of the tri-state area and to preserve the natural habitat of birds and other wildlife.

Eastern Iowa once had lush tallgrass prairies, sunny oak savannas, and vibrant oak woodlands. Throughout the last 200 years of land use and practices, the Midwest has lost the majority of these natural areas which defined our region. Join Natural Resources Ecologist Tony Vorwald as we discuss the natural history and restoration of remnant prairies, oak savannas, and oak woodlands in Jackson and Dubuque Counties.
Bio from Tony: I am the Natural Resources Ecologist for Jackson County Conservation and a prairie/savanna obsessive. I have lived all over the world, meaning Iowa, Minnesota, and Wisconsin. Rooted in Iowa, I strive to better manage the natural areas that I work for and educate folks on Iowa’s natural history and conservation needs. My educational background is that I have a Master’s in integrated Natural Resources from the University of Idaho, a B.S. of Environmental Science from the University of Dubuque, and an associate of applied science in Natural Resources Management from Hawkeye Community College.
Calendar of Events
We hold monthly programs from September through May on a variety of topics related to nature and the environment.
We also hold an annual Christmas bird count, an annual Duck Waddle at Green Island (traditionally the 2nd Saturday in March), and an annual spring species count (traditionally the Saturday before Mother’s Day), and we offer additional field trips throughout the year.
You can tailor your birding to your interest and activity level, and all levels of experience are welcome.

[from spring 2025 newsletter]
Question: Why do birds flock to gravel roads in the wintertime? Answer: Because they have no teeth! Instead, birds have a gizzard, a muscular part of their stomach that helps them grind up food. Small rocks and sand (or grit) are ingested by birds to create “teeth” in the gizzard.
