Assistant Curator of the Macaulay Library at the Cornell Lab of Ornithology, Benjamin Clock is also the author of 31 species accounts of Tyrant Flycatchers in volume 9 of Handbook of the Birds of the World and a sound and video recordist for the Macaulay Library. He writes, “The Macaulay archives have been built by dedicated recordists over the past nine decades. The Library is now the largest archive of its kind, with coverage of over 7,000 species of birds and thousands of amphibians, mammals, fish and insects. My talk, featuring video and sounds recorded across the globe, will take you on a journey through the history of the archives, chronicling recording expeditions from Lab founder Arthur A. Allen’s ground-breaking work in the early twentieth century to today’s efforts to document birds of the world with high-resolution multimedia specimens.”
