Wildlife watching

At Big Oaks National Wildlife Refuge

The refuge is always a great place to see wildlife. 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. Visitors can look for wildlife in the day use area on public use days.
