Biological Exuberance: Animal Homosexuality and Natural Diversity

Because of the omission and inaccessibility of information on animal homosexuality in the scientific literature, many zoologists are themselves unaware of the full extent of the phenomenon. One of the most unfortunate consequences of this is that misinformation (and absence of information) about the subject is widely disseminated and perpetuated from one source to the next. On discovering homosexual activity in a particular species they are studying firsthand—and being unable to find more than a handful of comparable examples in a cursory literature search—many zoologists acquire the mistaken impression that their observations of this behavior are somehow unique or unusual. At that point they may issue blanket statements to the effect that homosexual activity is rare or previously unreported in the form or species they are observing. Such statements are then often repeated by other biologists and become definitive pronouncements on the subject. As recently as 1993, for example, a scientist reporting on Hooded Warblers could claim that male homosexual pairs had not previously been seen in wild birds—when, in fact, such pairs were documented more than a quarter century earlier in Antbirds, Orange-fronted Parakeets, Golden Plovers, and Mallard Ducks, and thereafter in Black Swans, Scottish Crossbills, Black-billed Magpies, and Pied Kingfishers, among others.⁶⁷ Scientists studying same-sex pairs of Black-headed Gulls in captivity asserted in 1985 that this behavior had yet to be seen in this species in the wild—apparently unaware of a description of a male homosexual pair in wild Black-headed Gulls published in a Russian zoology journal just a year earlier. And researchers who discovered same-sex matings in Adélie and Humboldt Penguins and in Kestrels stated that they did not know of any comparable phenomena in other species of penguins or birds of prey, when in fact homosexual activity in King Penguins, Gentoo Penguins, and Griffon Vultures had previously been reported in the literature.⁶⁸

Sadly, omission and misinformation on the subject of animal homosexuality have ramifications far beyond the individual scientific articles in which they occur. Reference works such as those mentioned above are frequently consulted by researchers in other fields, and they are also the source of much of the information on animal behavior that is presented to the general public. As the quote at the beginning of this subsection indicates, the cycle is also perpetuated through each new generation of scientists as the textbooks they use (or the professors who instruct them) continue to offer inaccurate or incomplete information on the subject (when they aren’t completely silent on the topic). It is no surprise, then, that many scientists—and, by extension, most nonscientists—continue to harbor the erroneous impression that homosexuality does not exist in animals or is at best an isolated and anomalous phenomenon. When erasure and silence surround the subject among zoologists, misinformation and prejudice readily fill in the gaps—both in the scientific community and beyond.

To conclude this examination of homophobic attitudes in the scientific establishment, one simple observation can be made: given the considerable obstacles encountered in the recording, analysis, and discussion of the subject, it is remarkable that any descriptions of animal homosexuality make it to the pages of scientific journals and monographs (or to a wider audience). A great deal of progress is being made, and the situation today is certainly improved over that of even a decade ago. Moreover, none of this discourse would even be possible without the invaluable work of zoologists and wildlife biologists who study animals firsthand and report their findings—however flawed that study and reporting may be at times. Nevertheless, the examples of animal homosexuality currently contained in the zoological literature represent only the tip of the iceberg. Many more remain to be discovered, recorded, and granted the scientific attention that has so repeatedly been denied them in the past.
