Similar assumptions have frequently guided the treatment of actual sexual behavior, most blatantly when same-sex activity is excluded entirely from the definition of what constitutes sexual activity. One researcher, for example, only considered cases involving “insertion of the penis into the vagina” to be genuine examples of sexual penetration in Savanna (Olive) Baboons, and a study of Right Whales classified behavior as sexual only if it occurred in groups containing both males and females. A recent study of Moose defined sexual mounting behavior solely as “a male mounting a female,” while any mounting activity in Cattle Egrets “in which male-female cloacal [genital] contact appeared to be impossible” was classified a priori as “incomplete” or unsuccessful sexual activity.34 Anal and oral intercourse are not the only forms of penetration excluded by these sorts of definitions. In discussing homosexual activity in female Squirrel Monkeys, one scientist bluntly asserted that clitoral penetration—the insertion of one female’s clitoris into another’s vagina—was anatomically impossible: “Because of the structure of the female genitalia, however, intromission between females is not possible.” In fact, the clitoris in Squirrel Monkeys and many other female mammals becomes conspicuously erect during sexual arousal, and actual clitoral penetration has been documented during lesbian sexual activity in Bonobos, and it may also occur in Spotted Hyenas.35 The phallocentric viewpoint expressed in comments such as these is merely the most recent manifestation of attitudes that can be traced back to some of the earliest descriptions of animal homosexuality. In 1922, for example, one scientist wrote of female homosexual interactions in Savanna (Chacma) Baboons, “The physical completion of the act was, of course, impossible and it seemed more like an impulsive action in which there was no real sexual excitement involved.”36 This perfectly epitomizes the sort of stereotypes and misinformation that have continued to engulf homosexuality to this day, in both animals and people.
Mock Courtships and Sham Matings
The attitude that homosexual activity is not “genuine” sexual, courtship, or pair-bonding behavior is also sometimes made explicit in the descriptions and terminology used by researchers. In spite of witnessing two male homosexual mounts during a morning spent observing Ruffs, for example, one ornithologist reported offhandedly that “there were no real copulations” because no heterosexual mounting took place; a similar comment was made by a scientist studying Bonnet Macaques.37 This attitude is also encoded directly in the words used for homosexual behaviors: rarely do animals of the same sex ever simply “copulate” or “court” or “mate” with one another (as do animals of the opposite sex). Instead, male Walruses indulge in “mock courtship” with each other, male African Elephants and Gorillas have “sham matings,” while female Sage Grouse and male Hanuman Langurs and Common Chimpanzees engage in “pseudo-matings.” Musk-oxen participate in “mock copulations,” Mallard Ducks of the same sex form “pseudo-pairs” with each other, and Blue-bellied Rollers have “fake” sexual activity. Male Lions engage in “feigned coitus” with one another, male Orang-utans and Savanna Baboons take part in “pseudo-sexual” mountings and other behaviors, while Mule Deer and Hammerheads exhibit “false mounting.” Bonobos, Japanese and Rhesus Macaques, Red Foxes, and Squirrels all perform “pseudo-copulations” with animals of the same sex.38 Amid this abundance of counterfeit sexual activity, one thing is all too reaclass="underline" the level of denial on the part of some zoologists in dealing with this subject.39
Even use of the term homosexual is controversial. Although the majority of scientific sources on same-sex activity classify the behavior explicitly as “homosexual” —and a handful even use the more loaded terms gay or lesbian40—many scientists are nevertheless loath to apply this term to any animal behavior. In fact, a whole “avoidance” vocabulary of alternate, and putatively more “neutral,” words has come into use. “Male-male” or “female-female” activity is the most common appellation, although some more oblique designations have also appeared, such as “male-only social interactions” in Killer Whales or “multifemale associations” for same-sex pairs in Roseate Terns and some Gulls. Homosexual activities are also called “unisexual,” “isosexual,” “intrasexual,” or “ambisexual” (meaning single-sex, same-sex, within-sex, and bisexual, respectively) in various species such as Gorillas, Ruffs, Stumptail Macaques, Hooded Warblers, and Rhesus Macaques. The use of “alternate” words such as unisexual is sometimes advocated precisely because of the homophobia evoked by the term homosexuaclass="underline" one scientist reports that an article on animal behavior containing homosexual in its title was widely received with a “lurid snicker” by biologists, many of whom never got beyond the “sensationalistic wording” of the title to actually read its contents.41
Occasionally there are directly opposing assertions regarding the suitability of the term homosexual for the same behavior and species. In a relatively enlightened treatment of same-sex activities in Giraffes, for example, one zoologist stated, “Such usage [of the term homosexual] is acceptable provided it is used without the usual human connotation of stigma and sexual abnormality … . In giraffes the erection of the penis, mounting, and even possibly orgasm leaves little doubt as to the sexual motivation behind these actions.” In contrast, a decade later another zoologist objected, “Considerable significance has been attached to the fact that necking males sometimes show penis erections and that one may mount the other … such behavior has been called ‘homosexual.’ However … I … do not feel that the use of the term homosexual, with its usual (human) connotation, is justified in this context.”42 Ironically, where the first scientist objected only to the stigma associated with the term as applied to people, the second objected to the connotation of genuinely sexual behavior in the term as applied to people.
When it comes to heterosexual activities, however, scientists are not at all adverse to making analogies with human behaviors. Opposite-sex courtship-feeding in birds is described as “romantic” and reminiscent of human lovers kissing, male canaries whose vocalizations attract female partners are said to sing “sexy” songs, while avian heterosexual monogamy and foster-parenting are compared to similar activities in people (in spite of the acknowledged differences in the behaviors involved). Even more flagrant anthropomorphizing sometimes occurs: male-female interactions in Savanna Baboons, for example, are likened to “May-December romances,” “flirting,” and other human courtship rituals in a “singles bar”; polyandry in Tasmanian Native Hens is termed “wife-sharing”; opposite-sex bonds between cranes who readily pair with one another are characterized as “magic marriages”; and heterosexually precocious male Bonobos are dubbed “little Don Juans.” Female fireflies that lure males of other species by courting and then eating them are labeled “femmes fatales,” and one scientist even uses the term gang-bang to describe group courtship and forced heterosexual activity in Domestic Goats. Regardless of whether these characterizations are appropriate, among zoologists it is still more acceptable (in practice if not in theory) to draw human analogies where heterosexuality is concerned.43
