The college’s Olentangy River Wetland Research Park is celebrating Earth Day in a big way. Today they’re hosting a “Green Lunch Series” tour of the wetlands. And tomorrow, Earth Day begins with an 8 a.m. bird walk led by world-renowned birder Bernie Master, followed by a 10 a.m. Easter egg hunt, wild-goose egg hunt, and muskrat search. The Easter eggs will be filled with an ecological gift, and hunters documenting goose-egg and muskrat finds with their cameras will earn a special prize.
