Jerry Widel, staff at Bickelhaupt Arboretum arranges the taxidermy display with the addition of the River Otter and Muskrat. The Arboretum holds a federal and state fish and game license to display the 26 mammals and reptiles and 53 birds in the collection. The mounting of these two new specimens was donated by Rick's Taxidermy of Clinton. Rick said, "These two mammals are representative of native (muskrat) and re-introduced (river otter) species." In the winter, the Arboretum Visitor's Center is open daily 8 - 5 or by appointment on weekends.
