Animal Homosexuality and Natural DiversityBook - 1999
Documents non-reproductive sexual behavior in animals, covering courtship, pair-bonding, copulation, and co-parenting
One of the New York Public Library's "25 Books to Remember" for 1999
Homosexuality in its myriad forms has been scientifically documented in more than 450 species of mammals, birds, reptiles, insects, and other animals worldwide. Biological Exuberance is the first comprehensive account of the subject, bringing together accurate, accessible, and nonsensationalized information. Drawing upon a rich body of zoological research spanning more than two centuries, Bruce Bagemihl shows that animals engage in all types of nonreproductive sexual behavior. Sexual and gender expression in the animal world displays exuberant variety, including same-sex courtship, pair-bonding, sex, and co-parenting—even instances of lifelong homosexual bonding in species that do not have lifelong heterosexual bonding.
Part 1, "A Polysexual, Polygendered World," begins with a survey of homosexuality, transgender, and nonreproductive heterosexuality in animals and then delves into the broader implications of these findings, including a valuable perspective on human diversity. Bagemihl also examines the hidden assumptions behind the way biologists look at natural systems and suggests a fresh perspective based on the synthesis of contemporary scientific insights with traditional knowledge from indigenous cultures.
Part 2, "A Wondrous Bestiary," profiles more than 190 species in which scientific observers have noted homosexual or transgender behavior. Each profile is a verbal and visual "snapshot" of one or more closely related bird or mammal species, containing all the documentation required to support the author's often controversial conclusions.
Lavishly illustrated and meticulously researched, filled with fascinating facts and astonishing descriptions of animal behavior, Biological Exuberance is a landmark book that will change forever how we look at nature.
A provocative survey of non-reproductive sexuality in the animal world examines instances of homosexuality among more than 450 species of mammals, birds, reptiles, fish, insects, and other animals, raising questions about the myth that homosexuality is uncommon in the natural world. 25,000 first printing.

- p. 19: Clitoral rubbing or other types of genital tribadism are found in female Bonobos, Gorillas, and Rhesus Macaques (among others), while males in several species (e.g., White-handed Gibbons, West Indian Manatees, and Gray Whales) rub their penises together or on each other's body. In male Bonobos, mutual genital rubbing sometimes takes the form of an activity with the colorful name of "penis fencing," in which the males hang suspended by their arms and rub their erect organs against each other.
