Mallard ducks feeding in shallow water

The refuge is always a great place to see wildlife and birds usually attract the most attention. There is an active eagle nest on Old Timbers Lake that can be observed throughout the summer months. Visitors can see Henslow's sparrows, cerulean warblers, worm-eating warblers and other migratory birds during the warm months of the year. River otters, bobcat and other mammals are also common. Several uncommon species of reptiles and amphibians, including rare to Indiana species like the crawfish frog, also occur on the refuge but are not always seen.  The refuge conducts special birding tours on request.   Volunteers are always welcome to assist with the Christmas Bird Count, the spring crawfish frog survey, and the summer North American Butterfly Survey.
