Kevin Mack grew up in Queens, New York, where birds were the one accessible part of the natural world. After spending summers in the Catskills and along the coast, he headed to Orono, Maine, where his college years found him birding as a complement to mountain biking, cross-country skiing, and rock climbing. Mack has worked for Patagonia, Inc. and the Great Basin Bird Observatory as an intern and employee. He helped found the Nevada Wilderness Project (NWP), a nonprofit group whose aim is to increase the amount of congressionally designated wilderness on Nevada’s federal public lands. He now works on behalf of NWP in Washington, D.C., and has found time to volunteer as a fieldworker for the second generation of the Maryland Breeding Bird Atlas project.
