Silent Thunder: In the Presence of Elephants

Naturalist and bioacoustics researcher Katy Payne stood near an elephant cage at a zoo and felt a strange "throb and flutter" in the air. When she later realized that the feeling was very like that caused by the lowest notes of a pipe organ, she embarked on a journey of scientific and personal discovery that took her to Africa to study how the huge mammals communicate. For years, she lived close to the elephants she loved, getting to know individuals and describing their long-distance infrasound "conversations." After her fifth such expedition, one third of the elephant population she was studying was killed in a planned cull by the Zimbabwean government. Whether or not you accept Payne's hypothesis that elephants are extraordinarily intelligent and capable of communicating with each other and with other species (including humans), you will find her descriptions of the animals compelling and compassionate. Her grief at the loss of her elephant friends is palpable, and she uses it to utmost effect in decrying not only the ivory trade, but the way in which humans have decided to live on the planet. --Therese Littleton
