Bowdoin College biologist Nathaniel T. Wheelwright will discuss his recent book, “The Naturalist’s Notebook,” Tuesday, May 8, at 6:30 p.m. at Belfast Free Library, 106 High St.

Wheelwright and best-selling author Bernd Heinrich co-wrote “The Naturalist’s Notebook” to teach nature lovers of all ages to be more mindful, curious and knowledgeable about the natural world, no matter where they live, using a calendar-journal format and Heinrich’s classic illustrations as inspiration. The book’s five-year calendar format helps readers create a long-term record and point of comparison for memorable natural events.

Wheelwright is the Bass Professor of Natural Sciences at Bowdoin and the 2015 winner of the Ecological Society of America’s Odum Award for Excellence in Ecology Education. He is also the author of numerous scientific publications and co-editor of “Monteverde: Ecology and Conservation of a Tropical Cloud Forest.” His presentation will describe the origin of the project and the joys, challenges and fulfillment of keeping a systematic nature journal. Books will be available to purchase.
