In late March 2015, ornithologist Bruce M. Beehler set off on a solo three-month trek to track songbird migration and the northward progress of spring through America. Traveling via car, canoe, bike, and on foot, Beehler followed woodland warblers and other neotropical songbird species from the southern border of Texas, where the birds first arrive after their winter sojourns in South America and the Caribbean, northward through the Mississippi drainage to its headwaters in Minnesota and onward to their nesting grounds in the north woods of Ontario. In North on the Wing , Beehler describes both the epic migration of songbirds across the country and the gradual dawning of springtime through the US heartland—the blossoming of wildflowers, the chorusing of frogs, the leafing out of forest canopies—and also tells the stories of the people and institutions dedicated to studying and conserving the critical habitats and processes of spring songbird migration. Inspired in part by Edwin Way Teale’s landmark 1951 book North with the Spring , this audiobook—part travelogue, part field journal, and part environmental and cultural history—is a fascinating firsthand account of a once-in-a-lifetime journey. It engages listeners in the wonders of spring migration and serves as a call for the need to conserve, restore, and expand bird habitats to preserve them for future generations of both birds and humans.
