"A scholarly, exhaustive, and utterly convincing refutation of the notion that human homosexuality is an aberration in nature . . . Bagemihl does realize that some among us will never be convinced that homosexuality occurs freely and frequently in nature. But his meticulously gathered, cogently delivered evidence will quash any arguments to the contrary." --Kirkus Reviews

"A brilliant and important exercise in exposing the limitations of received opinion . . . an exhaustively argued case that animals have multiple shades of sexual orientation." --Publishers Weekly

"Bagemihl has done an extraordinary job in compiling a vast bestiary . . . This book should surely become the standard reference work for research on the topics covered." --Nature

"A landmark in the literature of science." --Chicago Tribune

"By producing a work that is accessible to the general reader while engaging for the specialist, Bagemihl has accomplished a most extraordinary feat. In the tradition of the finest nonfiction, this is a book that will force us to reexamine who we are and what we believe." --The Philadelphia Inquirer

"For anyone who has ever doubted the 'naturalness' of homosexual, bisexual, and transgendered behaviors, this remarkable book, which demonstrates and celebrates the sexual diversity of life on earth, will surely lay those doubts to rest. The massive evidence of the wondrous complexity of sexuality in the natural world that Bagemihl has marshaled will inform, entertain, and persuade academic and lay readers alike. Biological Exuberance is a revolutionary work." --Lillian Faderman, author of Odd Girls and Twilight Lovers: A History of Lesbian Life in Twentieth-Century America
