Katy Payne  is a renowned acoustic biologist with a Quaker sensibility. She’s found her astonishment — and many life lessons — in listening to two of the world’s largest creatures. From the wild coast of Argentina to the rainforests of Africa, she discovered that humpback whales compose ever-changing songs and that elephants communicate across long distances by infrasound. Currently, she is a researcher in the bioacoustics research program of Cornell University’s Laboratory of Ornithology. She is was part of the research team that produced the original recording “Songs of the Humpback Whale.”
