| The deciduous hardwood forest and the Rock River provide habitat for a variety of wildlife. Nearly 175 species of birds can be observed during the year, though spring is a favorite time for observing migrating species. Bald eagles can be observed along the river during the winter months. The dominant trees of the upland forest - oaks - are bountiful at Black hawk, along with a variety of other hardwoods. Numerous wildflowers, shrubs and vines grow under their canopy. More than 30 wildflower species, including orchids (showy orchids), bloom in April and May. | ![]() |
