Grab the Kleenex: This is the final episode that TBL host Bill Thompson, III, recorded before succumbing to pancreatic cancer on March 25, 2019. Bill interviews Mark S. Garland, a naturalist who has been sharing his enthusiasm for nature for over 40 years. He is also the proud recipient of the Paul Bartsch Award for Distinguished Contributions to Natural History. Bird Watcher's Digest subscribers will recognize him as the author of "Birders Question Mark," a Q&A column that has featured in the magazine since 2015. Mark reveals what sparked his interest in nature and birds early in life, and how it evolved throughout his lifetime. He ends with advice for aspiring naturalists: Be persistent, follow your heart, and in the end, it will all work out!
