Over the past few decades, American society has increased its tolerance and acceptance of differing sexualities. Among the primate orderhomosexual behavior is most frequently observed in bonobos. However, it also occurs in other species, such as Japanese macaques and capuchin monkeys.
One pair of male rhesus monkeys reared in the laboratory with exclusive social access to each other during their second year of life were observed to display reciprocal mounting with anal penetration on several occasions. Their mounts were of comparable duration to those which have been observed in matching heterosexual pairs, by contrast with the brief mounts which are often observed in dominance interactions. The postures exhibited by the mounted male resembled those typical of females during heterosexual coitus, while the mounting male displayed the species-typical male copulatory position.

I saw the news reports that Morford refers to when they first appeared, but he writes about them with humour, style and verve, producing a piece which is irreverent but fun, as well as important. That positively adorable pair of them, at the Central Park Zoo, who had adopted an abandoned egg and then hatched it themselves and were raising the chick together as a couple, even though the chick was clearly not theirs — though of course how penguins can actually tell whose kid is whose is still a question. Never mind that now.
Non-reproductive sexual behavior consists of sexual activities animals participate in that do not lead to the reproduction of the species. Although procreation continues to be the primary explanation for sexual behavior in animalsrecent observations on animal behavior have given alternative reasons for the engagement in sexual activities by animals. Observed non-procreative sexual activities include non-copulatory mounting without penetration, or by the femaleoral sex, genital stimulation, anal stimulation, interspecies mating, and acts of affection.
In cooperative breeders, reproductive skew is extreme and leads to intense intrasexual competition for access to reproduction in both sexes. Given that securing the dominant position is costly, dominant animals should direct their aggressiveness towards same-sex subordinates that are potential competitors. Chemical communication has been reported to be involved in intrasexual competition in several mammalian species, and odour may be used as a cue to identify potential competitors.
Hi there. A question came to my mind another day, and I decided to ask around so that I would know whether somebody studied this topic or not. I tried google, but thought it might be easier to try a forum.
Below are seven such animals. Some of them you may already know about, but some of them are likely to surprise you. While the majority of male marsh harriers are covered in a grey down of feather and have yellow eyes, 40 per cent of these males resemble their female counterparts.
Yet, these are but two examples used in peer-reviewed scientific studies to demonstrate that animal homosexuality is persuasive. Analogous behavior is not essential behavior. Anal intercourse is to homosexuality as seeing is to sight. Neither homosexuality nor sight is definable in normal usage without its essential act.
