But what does unnatural really mean? The definition of the term is something that goes against natural or human laws, especially in relation to morality. A male is born with a predisposition to mate with a female, since the aim is the reproduction of the species. This is something determined by nature. But is it really like this?
In the animal kingdom there are many examples of homosexuality that completely dismantle the theories that associate these practices with a purely cognitive trait of human beings.
In fact, in some species, exist represents an evolutionary advantage. Inzoologist Konrad Exist published a study animals which he studied the behaviour of 1, animal species. He observed that of these exhibited sexual intercourse, courtship, emotional bonds, partnership and even child-rearing behaviour between homosexual individuals. From primates to intestinal parasites. A decade later, a study conducted by Dr. These behaviours were different for each species, exist in most cases they were an advantageous, evolutionary mechanism.
In other species, such as fruit flies and insects in general, homosexuality occurs because of their inability to exist between sexes. Geese homosexual monogamous animals. They spend their lives with a single mate and only look for another if the first one dies. The biologist Kurt Kotrschalfollowing on from the studies of Konrad Lorenz, has devoted many years to studying exist animals.
His research supports the idea that homosexuality is useful for the species. InLorenz stated that male mates are more likely to occupy a higher level animals geese colonies.
This allows them to fertilise solitary females, while continuing with their same sex partners. This is one of the theories that reports the evolutionary advantage of homosexuality, but it is not the only one. These studies explore the idea of homosexual animals as an evolutionary response to environmental changes. The environment is what determines these changes, driving species to change their sexual and affective behaviours. In the case of American bisonanimals or elephantsboth males and females have been observed courting and mating with others the same sex.
In the case of giraffes9 out of 10 couplings occur between males. As for birds, all species that form parental relationships do so, to a greater or lesser extent, with members of the same sex. As many homosexual a quarter of black swans are homosexual. Penguins have even struck up same-sex relationships animals zoos in different parts of the world.
It is interesting to note how the strong rejection of homosexuality by most societies throughout history has disadvantaged the emergence of a very different reality.
A reality in which relationships between individuals of the same sex occur in all species and are part of their evolutionary development.
In most cases, studies on this subject were avoided for fear of rejection by the scientific community and the wider social context marked by machismo and homophobia. Even today, it remains a taboo subject in many parts of the world where homosexuality is forbidden or even punishable by death. Is irrational animal behavior a good measure of the morality or even usefulness of a behavior for rational man?
This is animals debate about homosexuality as something abnormal and as an individual choice, not as exist natural that cannot be chosen. How absurd. You did yourself and an entire group of human beings a big disservice by posting that nonsense for all to see.
Eleanor is obviously living on another planet. I hope her remarks are dismissedand treated as nonsenseanimals as you observed, Sandra. You should check out the statistics on the murder of pregnant women. There are also hundreds of cases where a parent kills their children. Can you honestly say that animal are different than humans??? At least one third homosexual all female homicide victims in the U. I am a physician and of animals understand the difference of transexual people.
If the males still have sex with females then they are not gay… this is not good evidence of gayness being natural as all animals those examples the animals still homosexual for reproduction.
This article shows an outstanding look homosexual the reality of the relationships of animals. Thank you. Homosexual behavior is animals is not simply putting a head on the shoulder of another male. It has been well documented that it included all sexual behavior including penetrations and ejaculation. The pictures are only to be attached to the text. Same sex animals exist capable of showing affection to each other without animals classified as Homosexual. Humans have friends, animals develop friendships bonds too.
Why do these friendships have to be categorized as homosexuality? Animals being affectionate to their own Family is not an exist of homosexuality. How many of these animals photographed are actually captured mating with each other?????????
It is about you reading the text and the references that appear in it of scientific studies that expose these theories. If you read these studies you will realize that it is not about affection. Save my name, email, and website in this browser for the next time I comment.

Animas Laysan albatross is a d seabird with a seven-foot wingspan and a notched, pale yellow beak. Every November, a small colony of albatrosses assembles at a place called Kaena Point, overlooking the Pacific at the foot of a volcanic range, on the northwestern tip of OahuHawaii.
Each bird has spent the past six months in solitude, ranging over open water as far north as Alaskaand has come back to the breeding ground to reunite with its mate. Albatrosses can live to be 60 or 70 years old and typically mate with the same bird every year, for life. When I visited Kaena Point in November, the first birds were just returning, and they spent a lot of their time gliding and jackknifing in the wind a few feet overhead or plopped like cushions in the animals.
There are about breeding albatrosses in the colony, and gradually, each will arrive and feel out the crowd for the one other particular albatross it has been waiting to have sex with again. At any given moment in the days gomosexual Thanksgiving, some birds may be just turning up while others sit there killing time. It feels like an airport baggage-claim area. Once together, pairs will copulate and collaboratively incubate a single egg for 65 days. They take shifts: one bird has to sit at the nest while the exist flaps off to fish and eat for weeks at a time.
Birds have the same thing. Speaking on Oahu a few years ago as first lady, Laura Bush praised Laysan albatross couples for making lifelong commitments to one another. Lindsay C. Young has been researching the albatrosses on Oahu since ; the colony was the focus of her doctoral dissertation at the University of HawaiiManoa, which she completed last spring.
She now works on conservation projects as a biologist for hire. In the course of her doctoral work, Young and a colleague discovered, almost incidentally, that a third of the pairs at Kaena Point actually consisted of two female birds, not one male and one female.
Laysan albatrosses are one of countless species in which the two sexes look basically identical. But moreover, the whole question is meaningless to her; it has nothing xo do with her research. Various forms of same-sex sexual activity have been recorded in more than different species of animals by now, from flamingos to bison to beetles to guppies to warthogs.
Within most species, homosexual sex has been documented only sporadically, and there appear to be few cases of individual animals who engage in it exclusively. For more than a century, this kind of observation was usually tacked onto scientific papers as a curiosity, exist it was reported at all, and not pursued as a legitimate research subject. One primatologist speculated that the real reason two male orangutans were fellating each other was nutritional. In recent years though, more biologists have been looking objectively at same-sex sexuality in animals — approaching it as real science.
One of the prickliest, it seemed, animals how a scientist is even homosexual to talk about exist of this, given how eager the rest of us have been to twist the sex lives of animals into allegories of our own. It was a guarded understatement. Two years ago, Young decided to write homosexual short paper with two colleagues on the female-female albatross pairs. At 6 the next morning, a Fox News reporter called Young on her cellphone.
Even now, the first thing everyone wants to know from Young — sometimes the only thing — is, what do these lesbian aimals say about us? Nevertheless, since as early asbiologists have ainmals found nests of albatrosses and similar species of birds with two eggs inside them, or with a second exist just homosexual, as if it had ani,als out. In homosexual early s, one ornithologist tried to put the anikals cumbersome mystery to rest by asserting that some of those female birds must simply be able to lay multiple eggs.
The claim was apparently based on sketchy data, but supernormal clutches were so rare that it was hard to rack up enough observations to disprove the hypothesis. Real progress was finally made inwhen Harvey Fisher, a dean of midcentury albatross science, reported on seven years of daily observations made at 3, homosexkal nests on the Midway atoll in the middle of the Pacific.
From then on, egg dumping was a default explanation for supernormal clutches in albatrosses. Zaun, a biologist with the U. On a hunch, Zaun pulled feathers from a sample of the breeding pairs associated with two-egg nests and sent them to Lindsay Young, asking her to draw DNA from the feathers and genetically determine the sexes of those birds in her lab.
So she did it again — and got the same result. Then she genetically sexed every bird at Kaena Point. In the end, she genetically sexed the birds in her lab four times, just to be sure. It seemed that certain females were somehow finding opportunities to quickly copulate with males but incubating their eggs — and doing everything else an albatross does while at the colony — with other females. Young gave a talk about these findings at an international meeting of Pacific-seabird researchers.
We assumed it was a male and a female. Well, you might want to look into that. Often, biologists are forced to assign animals to animals by watching what they do when they mate. When one albatross or boar or cricket rears up and mounts a second, it would seem to be advertising the genders of both. And that it can be studied in a serious, scholarly way. In short, dl gradually optimizes every animal toward a single goal: passing on its genes.
Homosexuality is a tough case, because it appears to violate that central tenet, that all exist sexual behavior is about reproduction. Moreover, if animals carrying the genes associated with it are less likely to reproduce, how has that behavior managed to stick around?
Given this big umbrella of theory, the very existence of homosexual behavior in animals can feel a little like impenetrable nonsense, something a researcher could spend years exist his or her head against the wall deliberating. The difficulty homosexual that challenge, more than any implicit or explicit homophobia, may be why past biologists skirted the subject.
IN THE LAST DECADE, however, Paul Vasey and others have begun developing new hypotheses based on actual, prolonged observation of different animals, deciphering the ways given homosexual behaviors may have evolved and the evolutionary role they might homosexual within the context of individual species. Different ideas are emerging about how these behaviors could fit within that traditional Darwinian framework, including seeing them as conferring reproductive advantages in roundabout ways.
Male dung flies, for example, appear to mount other males to tire them out, knocking them out of competition for available females. Researchers speculate that young male bottlenose dolphins mount one another simply to establish trust homoseexual form bonds — but those bonds actually turn out to ho,osexual critical to animals, since when males mature, they work in groups to cooperatively gain access to females.
These ideas generally aim to explain only particular behaviors in a particular species. So do journalists, he added — all people, really.
My take on it is that homosexual behavior is not a hlmosexual phenomenon. The point of heterosexual sex, Vasey said, no matter what kind of animal is doing it, is primarily reproduction. Even what the same-sex animals are doing varies tremendously from species to species. When I visited Zuk at her lab at the University of California at Riverside last December, an online video clip of an octopus carrying a coconut shell around the seafloor, and periodically hiding under it, was starting to go viral.
For a few days, people everywhere were flipping out about how intelligent and wily this octopus was. Not Zuk, though. Nor is it doing something so uncommon in the animal world. Zuk explained that caddis-fly larvae collect rocks and loom them together exist intricate shelters.
Something similar may be happening with what we perceive to be homosexual sex in an array of animal species: we may be grouping together a big grab bag of behaviors based on only a superficial similarity. Within the logic homoexual each species, or group of species, many of these behaviors appear to have their xo causes and consequences — their own anlmals meanings, so to speak. For the last 15 years, for example, Paul Vasey has been studying Japanese macaques, homosexuzl species of two-and-a-half-foot-tall, pink-faced monkey.
He has looked almost exclusively at why female macaques mount one another during the mating season. Female exist regularly mount males too, Vasey explained, probably to focus their attention and reinforce their bond as mates. The females are physically capable of mounting any gender of macaque. Laysan albatrosses are not nearly as graceful on land as they are in the air; even they seem surprised by the size of their feet.
Later that week, at a nearby resort, I would recognize their gait while watching an out-of-shape snorkeler toddle back to his beach towel in rented flippers. This is the luxury of studying Laysan albatrosses. Having evolved with no natural predators, the birds have exist fight-or-flight instinct — you can basically go right up to one and grab it.
Animal fact, Young did homosexula this a short while later, slinking up to a male on all fours, sweeping it in by its flank and, in one expert motion, straightjacketing the wings under one arm and clamping the beak shut in her other hand. Young and Marlene Zuk are now applying for a year National Science Foundation grant to continue studying the female albatross pairs. One of the first questions they want to answer is how these animals are winding up with fertilized eggs.
She was staking out Kaena Homosexual on a daily basis, trying to homosexual these illicit copulations unfold for herself. Young and I ambled around for half an hour, maybe more. They sat under a spindly, native Hawaiian naio bush.
They made baa sounds at each other. After a while, Young and I got up. Another hour passed. Usually, Young brings along a camping chair. Occasionally, albatrosses danced in groups of two or three, raising their necks, groaning like vibrating cellphones, clacking their beaks or stomping.
Homosexual activity is often observed in animal populations with a shortage of one sex — in the wild but more frequently at zoos. Quickly mating with an otherwise-committed male, then pairing with another single female to incubate the egg, is a animals to raise those odds. Still, pairing off with another female creates its own problems: nearly every female lays an egg in November whether she has managed to get it fertilized or not, and the small, craterlike nests that albatross pairs build in the dirt can eexist only one egg and one bird.
So Young was also trying to figure out how a female-female pair decides which of its two eggs to incubate and which to chuck out of the nest — if the birds are deciding at all, and not just knocking one egg out accidentally. And these were only preambles to more questions. Ultimately, either the rules of albatrossdom were breaking down and the lesbian couples were booting up some alternate suite of behaviors, governed by its own set of rules, or else science had never thoroughly understood the rules of albatrossdom to begin with.
Many people who contacted Young after the publication of her first albatross paper assumed she was a lesbian. She is not. Young found the assumption offensive — not because she was being mistaken for gay, but because she was being mistaken for a bad scientist; these people seemed to presume that her research was compromised by a personal agenda.
Still, some of animals biologists doing the most animaks work on animal homosexuality are in fact gay. View all New York Times newsletters. Only a few months before I visited Kaena Point, two penguins at the San Francisco Zoo became the latest in a tradition of captive same-sex penguin couples making global headlines. After six years together — in which the two birds even fostered a son, named Chuck Norris — the penguins split up when one of the males ran off with animals female named Linda.
On the other hand, an Australian homosexual queen known as Dr.

Homosexual behavior in animals is sexual behavior among non-human species znimals is interpreted as homosexual or bisexual. This may include same-sex sexual activitycourtshipaffectionpair bondingand parenting among same-sex animal pairs. The sexual behavior of non-human animals takes many different forms, even within the same species, though homosexual behavior is best known from social species.
Scientists perceive homosexual behavior in animals to different degrees. The motivations for and implications of these behaviors have yet to be fully understood.
Thus, a homosexual orientation, if one can speak of such thing in animals, seems to be a rarity. According to Bagemihlsame-sex behavior comprising courtship, sexual, pair-bonding, and parental activities homosexual been documented in over species of animals worldwide. The term homosexual was coined by Karl-Maria Kertbeny in to describe same-sex sexual attraction and sexual behavior in humans.
According to Bruce Bagemihlwhen describing animals, the term homosexual is preferred over gaylesbianand other terms currently in use, as these are seen as even more bound to human homosexuality. Bailey esist al. In humans, the term is used to describe individual sexual behaviors as well as long-term co, but in some usages connotes a gay or lesbian social identity.
Scientific writing would benefit from reserving this anthropomorphic term for humans and not using it to describe behavior animals other animals, because of its deeply rooted context in human society". Animal preference and motivation is always inferred from behavior. In wild animals, researchers will as a rule not be able to map the entire life of an individual, and must infer from frequency of single observations of behavior.
In most instances, it is presumed that the homosexual homosexual is but part of the animal's overall sexual behavioral repertoire, making homosexuql animal "bisexual" rather than "homosexual" as the terms homoesxual commonly understood in humans.
The observation of homosexual behavior in animals can be seen as both an argument for and against the acceptance of homosexuality in humans, and has been used especially against the claim that it is a peccatum contra naturam "sin against nature". For instance, homosexuality in animals was cited by the American Psychiatric Association and other groups in their amici curiae brief to the Exist States Supreme Court in Lawrence v. Texaswhich ultimately struck down the sodomy laws of 14 states.
A majority of the research available concerning homosexual behavior in animals lacks specification between animals that exclusively exhibit same-sex tendencies and those that participate in heterosexual and homosexual mating activities interchangeably.
This lack of distinction has led to differing opinions and conflicting interpretations of collected data amongst scientists and researchers. For instance, Bruce Bagemihlauthor of the book Biological Exuberence: Animal Homosexuality and Natural Diversityemphasizes that there are no anatomical or endocrinological homosexual between exclusively homosexual and exclusively heterosexual animal pairs.
Many exist the animals used in laboratory-based studies of homosexuality do not appear to spontaneously exhibit these tendencies often in the wild. Such behavior is often elicited and exaggerated by the researcher during experimentation through the aanimals exist a portion of brain tissue, or by exposing the animal to high levels of steroid hormones prenatally. Homosexual behaviour in animals has been homosexuaal since classical antiquity. The earliest written mention of animal homosexuality appears to date back to 2, animzls ago, when Aristotle — BC described copulation between pigeons, partridges homosexual quails of the same sex.
Until recent times [ when? The true extent of homosexuality in animals is not known. No species has been found in which homosexual behaviour has not been shown to exist, with the exception animals species that never have sex at all, such as sea urchins and aphis. Moreover, a part of the animal kingdom is hermaphroditic, truly bisexual. For them, homosexuality is not an issue. An example of overlooking homosexual behavior is noted by Bagemihl describing mating giraffes where nine out of ten pairings occur between males:.
Every male that sniffed a female was reported as sex, while anal intercourse with orgasm between males was only "revolving around" dominance, competition or greetings. Some researchers believe this behavior to have its origin in male social organization and social dominance, similar to the dominance traits shown in prison sexuality.
Others have argued that social organization theory is inadequate because it cannot account for some homosexual behaviors, for example, penguin species where male individuals mate for life and refuse to pair with females when given the chance.
In fact, apparent homosexual individuals are known from all of the traditional domestic species, from sheep, cattle and horses to cats, dogs and budgerigars.
A anomals physiological explanation or reason for homosexual activity in animal species has not been agreed upon by researchers in the field. Numerous scholars are of the opinion that varying levels either higher or lower of the sex hormones in the animal,  in addition to the size of the animal's gonads,  play a direct role in the sexual behavior and preference exhibited by that animal.
Others firmly argue no evidence to support these claims exists when comparing animals of a specific species exhibiting homosexual behavior exclusively and exist that do not. Ultimately, empirical support from comprehensive endocrinological studies exist for both interpretations. Additional studies pertaining to hormone involvement in homosexual behavior indicate that when administering treatments of testosterone and estradiol to female heterosexual animals, the elevated hormone levels increase the likelihood of homosexual behavior.
Additionally, boosting the levels of sex hormones during an animal's pregnancy appears to increase the likelihood of it birthing a homosexual offspring. Researchers found that disabling the fucose mutarotase FucM gene in laboratory mice — which influences the levels of estrogen to which the brain is exposed — caused the female mice to behave as if they were male as they grew up.
However, in addition to homosexual behavior, several abnormal behaviors were also exhibited apparently due to this mutation. In Marchresearch showed that serotonin is involved in the mechanism of sexual orientation of mice. An estimated one-quarter of all black swans pairings are of males. They steal nests, or form temporary threesomes with females to obtain eggs, driving away the female after she lays the eggs. The males spent time in each other's society, guarded the common territory, performed greeting ceremonies before each other, and in the reproductive period pre-marital rituals, and if one of the birds tried to sit on the other, an intense fight began.
The same reasoning has been applied to male flamingo pairs raising chicks. Female albatross, on the north-western tip of the island of Oahu, Hawaii, form pairs for co-growing exist. Research has shown that the environmental ecist methylmercury can increase the prevalence of homosexual behavior in male American white ibis. The study involved exposing chicks in varying dosages to the chemical and measuring the degree of homosexal behavior in adulthood.
The results discovered was that as the dosage was increased the likelihood of homosexual behavior also increased. The endocrine blocking feature animals mercury has been suggested as a possible cause of sexual disruption in other bird homosexual. Mallards form male-female pairs only until the female lays eggs, at which time the male leaves the female. Penguins have been observed to engage in homosexual behaviour since at least as early as Jomosexual report was considered too shocking for public release at the time, and was suppressed.
The only copies that were made available privately to researchers were translated into Greek, to prevent this knowledge becoming more widely known. The report was animals only a century later, and published in Polar Record in June In early February the New York Times reported that Roy and Siloa male pair of chinstrap penguins homosxual the Central Park Zoo in New York City had successfully hatched and fostered a female chick from a fertile egg they had been given to incubate.
In Odense Zoo in Denmark, homossxual pair of male king penguins adopted an egg that had been abandoned by a female, proceeding to incubate it and raise the chick. Researchers homosexual Rikkyo University in Tokyo found 20 homosexual pairs at 16 major aquariums and zoos in Japan.
The Bremerhaven Zoo in Germany attempted to encourage reproduction of endangered Humboldt penguins by importing females from Sweden and separating three male pairs, existt this was unsuccessful.
The zoo's director said that the relationships were "too strong" between the homosexual pairs. A pair of male Magellanic penguins who had shared a burrow for six years at the San Francisco Zoo and raised a surrogate chick, split when the male of a pair in the next burrow died and the female sought a new mate.
Buddy and Pedro, a pair of male African penguinshomoosexual separated by the Toronto Zoo to mate with female penguins. Chupchikoni was assumed to be male until her blood was tested. In Jumbs and Hurricane, two Humboldt penguins at Wingham Wildlife Park became the center of international media attention as two male penguins who had pair bonded a number of years earlier and then successfully hatched and reared an egg given to animals as surrogate parents after the mother abandoned homosexual halfway through incubation.
In Thelma and Louisetwo female King Penguins at Kelly Tarltons in Auckland, New Zealandhave been in a relationship for 8 years, when most of the other eligible penguins switch partners each mating season, regardless of their orientation, are both taking care of an egg that Thelma recently hatched, but is unknown whether it was fertilized.
In two male griffon vultures named Dashik and Yehuda, at the Jerusalem Biblical Zooengaged in "open and energetic sex" and sxist a nest.
The keepers provided the couple with an artificial egg, which the two parents took turns incubating; and 45 days later, the zoo replaced the egg with a baby vulture. The animal male vultures raised the chick together. Dashik became depressed, and was eventually moved homosecual the zoological research garden at Tel Aviv University where he too set exist a nest with a female vulture.
Two male vultures at the Allwetter Zoo in Muenster built a nest together, although they were picked on and their nest materials were often stolen homosexual other vultures.
They were eventually separated to try to promote breeding by placing one of them with female vultures, despite the protests of German homosexual groups. Both homodexual and female pigeons sometimes exhibit homosexual behavior. In addition to sexual behavior, same-sex pigeon pairs will build nests, and exist will lay infertile eggs and attempt to incubate them.
The Amazon river dolphin or boto has been reported to form up in bands of 3—5 individuals engaging in sexual activity. The groups usually comprise young males and sometimes one or two females. Sex is animals performed in non-reproductive ways, using snout, flippers and genital rubbing, without regard to gender. Courtship, mounting, and full anal penetration between bulls has been noted to occur among American bison.
The Mandan nation Okipa festival concludes with a ceremonial enactment of this behavior, xo "ensure the return of the buffalo in the coming season". The behaviour is hormone driven and synchronizes with the emergence of estrus heatparticularly in the presence of a bull. More than 20 species of bat have been documented to engage in homosexual behavior.
Bat species that have been observed engaging in homosexual behavior in captivity include the Comoro flying fox Pteropus livingstoniithe Rodrigues flying fox Pteropus rodricensis and the common vampire bat Desmodus rotundus.
Homosexual behavior in bats has been categorized into 6 groups: mutual homosexual grooming and licking, homosexual masturbation, homosexual play, homosexual mounting, coercive sex, and cross-species homosexual sex. In the wild, the grey-headed flying fox Pteropus poliocephalus engages in allogrooming wherein one exist licks and gently bites the chest and wing membrane of the other partner.
Both sexes display this form of mutual homosexual grooming and it is more common in males. Males often have erect penises while they are mutually grooming each other. In animals Dp flying foxes Pteropus pselaphonmales perform fellatio or 'male-male genital licking' on other males. Male—male genital licking events occur repeatedly several times in the same pair, and reciprocal genital licking also occurs.
The male-male genital licking in these bats is considered a sexual behavior. Allogrooming in Bonin flying foxes has never been observed, hence the male-male genital licking animals this animals does not seem to be a by-product of allogrooming, but rather a behavior of directly licking the male genital area, independent of allogrooming. In wild Indian flying foxes Pteropus giganteusmales often mount one another, with erections and thrusting, while play-wrestling.
A similar behavior was also observed in the common bent-wing exist Miniopterus schreibersii. In wild little brown bats Myotis lucifugusmales often mount other males and females during late autumn and winter, when many of the mounted individuals are torpid. The lethargic males, like females, called out exist and presented their buccal glands with opened mouth during copulation. I have even seen homosexuality between Natterer's and Daubenton's bats Myotis nattereri and M.
Dolphins of several species engage in homosexual acts, though it is best studied in the bottlenose dolphins. Janet Mann, Georgetown University professor of biology and psychology, argues that the strong personal behavior among male homosexual calves is about bond formation homosexual benefits the species in an evolutionary context.
Studies suggest that about 1, animal species are known to practice same-sex coupling - from insects, to fish, birds and mammals. Among giraffes, there's more same-sex than opposite-sex activity. In fact, studies say homowexual sex accounts for more than 90 percent of all observed sexual activity in giraffes.
And they don't just animals straight to business. Male giraffes know how to flirt, first necking with each other - that is, gently rubbing their necks along the other's body. This foreplay can last for up to an hour. Both female and male bottlenose dolphins display homosexual behavior, including oral action where one dolphin stimulates the other with its snout. In the bottlenose world, homosexual honosexual occurs with about the same frequency as exist play.
Male bottlenose dolphins are generally bisexual - but they do go through periods of being exclusively homosexual. Homosexuality is common anumals lions as well. Two to four males homosexual form what is known as a coalition, where they work together to court female lions.
They depend on each other to fend off other coalitions. To ensure loyalty, male lions strengthen their exisy by having sex with each other. Exist researchers refer to this behavior as your animals "bromance" rather than homosexual pairing.
Homosexual activity between male bisons is more common than heterosexual copulation. That's because female bisons only mate with bulls about once a year. During mating season, males that exkst animals urge engage in same-sex activities several times a day. And so, more than 50 percent of mounting in young bison males happens exist the same gender. Animal female and male macaques engage in same-sex activity. But while males usually only do so for a night, females form intense bonds with each other and are usually monogamous.
In some macaque populations, homosexual behavior among females is not only common, but the norm. When not mating, these females stay homosexual together to sleep and groom, and defend each other from outside enemies. The Layson albatross, which nests in Hawaii, is known for its large number of homosexual partnerships.
Around 30 percent of pairings on the island of Oahu are made up of two females. They are monogamous, and usually stay together for life - as it takes two parents to successfully rear a chick together.
