Birding at Dixon Waterfowl Refuge


Hone your waterfowl identification skills as you explore this magnificent wetland restoration in Putnam County. In 2001, the drainage pumps were turned off and the floodplain was allowed to re-establish. Today, the Dixon Waterfowl Refuge at Hennepin and Hopper Lakes  is a mosaic of lakes, marshes, seeps, savannas, and prairies that support an impressive array of birds, butterflies, dragonflies and damselflies, as well as emergent aquatic plants and prairie-dwelling grasses and flowers.  Wonderful birding opportunities occur year round, peaking during both the spring and fall migration periods when tens of thousands of ducks and other species can be viewed on a daily basis from the observation tower. We’ll meet at the Arboretum on Wednesday to talk about waterfowl ID and the history of the refuge, and review the checklist of birds we might expect to see. Then we’ll explore the site in person on Saturday morning.
