Homosexual behavior in animals – Wikipedia

Homosexual behavior in animals is sexual behavior among non-human species that is interpreted as homosexual or bisexual. This may include same-sex sexual activity, courtship, affection, pair bonding, and parenting among same-sex animal pairs.[1][2][3][4] Research indicates that various forms of this are found in every major geographic region and every major animal group. 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, since most species have yet to be fully studied.[5] According to Bruce Bagemihl, the animal kingdom engages in homosexual behavior "with much greater sexual diversity including homosexual, bisexual and nonreproductive sex than the scientific community and society at large have previously been willing to accept."[6] Bagemihl adds, however, that this is "necessarily an account of human interpretations of these phenomena".[7] Simon LeVay introduced caveat that "[a]lthough homosexual behavior is very common in the animal world, it seems to be very uncommon that individual animals have a long-lasting predisposition to engage in such behavior to the exclusion of heterosexual activities. Thus, a homosexual orientation, if one can speak of such thing in animals, seems to be a rarity."[8] One species in which exclusive homosexual orientation occurs, however, is that of domesticated sheep (Ovis aries).[9][10] "About 10% of rams (males), refuse to mate with ewes (females) but do readily mate with other rams."[10]

According to Bagemihl (1999), same-sex behavior (comprising courtship, sexual, pair-bonding, and parental activities) has been documented in over 450 species of animals worldwide. [11]

The term homosexual was coined by Karl-Maria Kertbeny in 1868 to describe same-sex sexual attraction and sexual behavior in humans.[12] Its use in animal studies has been controversial for two main reasons: animal sexuality and motivating factors have been and remain poorly understood, and the term has strong cultural implications in western society that are irrelevant for species other than humans.[13] Thus homosexual behavior has been given a number of terms over the years. According to Bruce Bagemihl, when describing animals, the term homosexual is preferred over gay, lesbian, and other terms currently in use, as these are seen as even more bound to human homosexuality.[14]

Bailey et al. says: "Homosexual: in animals, this has been used to refer to same-sex behavior that is not sexual in character (e.g. homosexual tandem running in termites), same-sex courtship or copulatory behavior occurring over a short period of time (e.g. homosexual mounting in cockroaches and rams) or long-term pair bonds between same-sex partners that might involve any combination of courting, copulating, parenting and affectional behaviors (e.g. homosexual pair bonds in gulls). In humans, the term is used to describe individual sexual behaviors as well as long-term relationships, 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 in other animals, because of its deeply rooted context in human society".[15]

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. The correct usage of the term homosexual is that an animal exhibits homosexual behavior or even same-sex sexual behavior; however, this article conforms to the usage by modern research,[14][16][17][18][pageneeded][19] applying the term homosexuality to all sexual behavior (copulation, genital stimulation, mating games and sexual display behavior) between animals of the same sex. In most instances, it is presumed that the homosexual behavior is but part of the animal's overall sexual behavioral repertoire, making the animal "bisexual" rather than "homosexual" as the terms are commonly understood in humans.[18][pageneeded], but cases of homosexual preference and exclusive homosexual pairs are known.[20]

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 United States Supreme Court in Lawrence v. Texas, which ultimately struck down the sodomy laws of 14 states.[21][22]

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 Bagemihl, author of the book Biological Exuberence: Animal Homosexuality and Natural Diversity, emphasizes that there are no anatomical or endocrinological differences between exclusively homosexual and exclusively heterosexual animal pairs.[23][pageneeded] However, if the definition of "homosexual behavior" is made to include animals that participate in both same-sex and opposite-sex mating activities, hormonal differences have been documented among key sex hormones, such as testosterone and estradiol, when compared to those who participate solely in heterosexual mating.[24]

Many of 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 destruction of a portion of brain tissue, or by exposing the animal to high levels of steroid hormones prenatally.[25][pageneeded] Information gathered from these studies is limited when applied to spontaneously occurring same-sex behavior in animals outside of the laboratory.[25]

Homosexual behaviour in animals has been discussed since classical antiquity. The earliest written mention of animal homosexuality appears to date back to 2,300 years ago, when Aristotle (384322 BC) described copulation between pigeons, partridges and quails of the same sex.[26] The Hieroglyphics of Horapollo, written in the 4th century AD by the Egyptian writer Horapollo, mentions "hermaphroditism" in hyenas and homosexuality in partridges.[26] The first review of animal homosexuality was written by the zoologist Ferdinand Karsch-Haack in 1900.[26]

Until recent times, the presence of same-sex sexual behavior was not "officially" observed on a large scale, possibly due to observer bias caused by social attitudes to same-sex sexual behavior,[27] innocent confusion, lack of interest, distaste, scientists fearing loss of their grants or even from a fear of "being ridiculed by their colleagues".[28][29] Georgetown University biologist Janet Mann states "Scientists who study the topic are often accused of trying to forward an agenda, and their work can come under greater scrutiny than that of their colleagues who study other topics."[30] They also noted "Not every sexual act has a reproductive function ... that's true of humans and non-humans."[30] It appears to be widespread amongst social birds and mammals, particularly the sea mammals and the primates. The true extent of homosexuality in animals is not known. While studies have demonstrated homosexual behavior in a number of species, Petter Bckman, the scientific advisor of the exhibition Against Nature? in 2007, speculated that the true extent of the phenomenon may be much larger than was then recognized:

No species has been found in which homosexual behaviour has not been shown to exist, with the exception of 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.[28]

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.[31]

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, particularly Bagemihl, Joan Roughgarden, Thierry Lod[32] and Paul Vasey suggest the social function of sex (both homosexual and heterosexual) is not necessarily connected to dominance, but serves to strengthen alliances and social ties within a flock. 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.[33][34] While reports on many such mating scenarios are still only anecdotal, a growing body of scientific work confirms that permanent homosexuality occurs not only in species with permanent pair bonds,[19] but also in non-monogamous species like sheep.

One report on sheep cited below states:

Approximately 8% of rams exhibit sexual preferences [that is, even when given a choice] for male partners (male-oriented rams) in contrast to most rams, which prefer female partners (female-oriented rams). We identified a cell group within the medial preoptic area/anterior hypothalamus of age-matched adult sheep that was significantly larger in adult rams than in ewes...[35]

In fact, apparent homosexual individuals are known from all of the traditional domestic species, from sheep, cattle and horses to cats, dogs and budgerigars.[36][pageneeded]

A definite 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,[37] in addition to the size of the animal's gonads,[24] 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 those that do not. Ultimately, empirical support from comprehensive endocrinological studies exist for both interpretations.[37][38] Researchers found no evidence of differences in the measurements of the gonads, or the levels of the sex hormones of exclusively homosexual western gulls and ring-billed gulls.[39] However, when analyzing these differences in bisexual rams, males were found to have lower levels of testosterone and estradiol in their blood, as well as smaller gonads than their heterosexual counterpart.[citation needed]

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.[37]

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. "The mutant female mouse underwent a slightly altered developmental programme in the brain to resemble the male brain in terms of sexual preference" said Professor Chankyu Park of the Korea Advanced Institute of Science and Technology in Daejon, South Korea, who led the research. His most recent findings have been published in the BMC Genetics journal on July 7, 2010.[40][41] Another study found that by manipulating a gene in fruit flies (Drosophila), homosexual behavior appeared to have been induced. However, in addition to homosexual behavior, several abnormal behaviors were also exhibited apparently due to this mutation.[42]

In March 2011, research showed that serotonin is involved in the mechanism of sexual orientation of mice.[43][44] A study conducted on fruit flies found that inhibiting the dopamine neurotransmitter inhibited lab-induced homosexual behavior.[45]

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.[1][2] More of their cygnets survive to adulthood than those of different-sex pairs, possibly due to their superior ability to defend large portions of land. The same reasoning has been applied to male flamingo pairs raising chicks.[46][47]

Female albatross, on the north-western tip of the island of Oahu, Hawaii, form pairs for co-growing offspring. On the observed island, the number of females considerably exceeds the number of males (59% N=102/172), so 31% of females, after mating with males, create partnerships for hatching and feeding chicks. Compared to male-female couples female partnerships have a lower hatching rate (41% vs 87%) and lower overall reproductive success (31% vs. 67%).[48]

Research has shown that the environmental pollutant 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 homosexual behavior in adulthood. The results discovered was that as the dosage was increased the likelihood of homosexual behavior also increased. The endocrine blocking feature of mercury has been suggested as a possible cause of sexual disruption in other bird species.[49][50]

Mallards form male-female pairs only until the female lays eggs, at which time the male leaves the female. Mallards have rates of male-male sexual activity that are unusually high for birds, in some cases, as high as 19% of all pairs in a population.[36][pageneeded] Kees Moeliker of the Natural History Museum Rotterdam has observed one male mallard engage in homosexual necrophilia.[51]

Penguins have been observed to engage in homosexual behaviour since at least as early as 1911. George Murray Levick, who documented this behaviour in Adlie penguins at Cape Adare, described it as "depraved". The 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 unearthed only a century later, and published in Polar Record in June 2012.[52]

In early February 2004 the New York Times reported that Roy and Silo, a male pair of chinstrap penguins in 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.[21] Other penguins in New York zoos have also been reported to have formed same-sex pairs.[53][54]

In Odense Zoo in Denmark, a pair of male king penguins adopted an egg that had been abandoned by a female, proceeding to incubate it and raise the chick.[55][56] Zoos in Japan and Germany have also documented homosexual male penguin couples.[33][34] The couples have been shown to build nests together and use a stone as a substitute for an egg. Researchers at 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, but this was unsuccessful. The zoo's director said that the relationships were "too strong" between the homosexual pairs.[57] German gay groups protested at this attempt to break up the male-male pairs[58] but the zoo's director was reported as saying "We don't know whether the three male pairs are really homosexual or whether they have just bonded because of a shortage of females ... nobody here wants to forcibly separate homosexual couples."[59]

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.[60]

Buddy and Pedro, a pair of male African penguins, were separated by the Toronto Zoo to mate with female penguins.[61][62] Buddy has since paired off with a female.[62]

Suki and Chupchikoni are two female African penguins that pair bonded at the Ramat Gan Safari in Israel. Chupchikoni was assumed to be male until her blood was tested.[63]

In 2014 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 them as surrogate parents after the mother abandoned it halfway through incubation.[64]

In 1998 two male griffon vultures named Dashik and Yehuda, at the Jerusalem Biblical Zoo, engaged in "open and energetic sex" and built 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 two male vultures raised the chick together.[65] A few years later, however, Yehuda became interested in a female vulture that was brought into the aviary. Dashik became depressed, and was eventually moved to the zoological research garden at Tel Aviv University where he too set up a nest with a female vulture.[66]

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 by 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.[67]

Both male and female pigeons sometimes exhibit homosexual behavior. In addition to sexual behavior, same-sex pigeon pairs will build nests, and hens will lay (infertile) eggs and attempt to incubate them.[citation needed]

The Amazon river dolphin or boto has been reported to form up in bands of 35 individuals engaging in sexual activity. The groups usually comprise young males and sometimes one or two females. Sex is often performed in non-reproductive ways, using snout, flippers and genital rubbing, without regard to gender.[68] In captivity, they have been observed to sometimes perform homosexual and heterosexual penetration of the blowhole, a hole homologous with the nostril of other mammals, making this the only known example of nasal sex in the animal kingdom.[68][69] The males will sometimes also perform sex with males from the tucuxi species, a type of small porpoise.[68]

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, to "ensure the return of the buffalo in the coming season".[70] Also, mounting of one female by another (known as "bulling") is extremely common among cattle. The behaviour is hormone driven and synchronizes with the emergence of estrus (heat), particularly in the presence of a bull.

More than 20 species of bat have been documented to engage in homosexual behavior.[26][71] Bat species that have been observed engaging in homosexual behavior in the wild include:[26]

Bat species that have been observed engaging in homosexual behavior in captivity include the Comoro flying fox (Pteropus livingstonii), the Rodrigues flying fox (Pteropus rodricensis) and the common vampire bat (Desmodus rotundus).[26]

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.[26][71]

In the wild, the grey-headed flying fox (Pteropus poliocephalus) engages in allogrooming wherein one partner 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. Like opposite-sex grooming partners, same-sex grooming partners continuously utter a pre-copulation call, which is described as a "pulsed grating call," while engaged in this activity.[26][71]

In wild Bonin flying foxes (Pteropus pselaphon), males perform fellatio or 'male-male genital licking' on other males. Malemale 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 in this species does not seem to be a by-product of allogrooming, but rather a behavior of directly licking the male genital area, independent of allogrooming.[71] In captivity, same-sex genital licking has been observed among males of the Comoro flying fox (Pteropus livingstonii) as well as among males of the common vampire bat (Desmodus rotundus).[26][71]

In wild Indian flying foxes (Pteropus giganteus), males often mount one another, with erections and thrusting, while play-wrestling.[26] Males of the long-fingered bat (Myotis capaccinii) have been observed in the same position of male-female mounting, with one gripping the back of the others fur. A similar behavior was also observed in the common bent-wing bat (Miniopterus schreibersii).[26]

In wild little brown bats (Myotis lucifugus), males often mount other males (and females) during late autumn and winter, when many of the mounted individuals are torpid.[26] 35% of matings during this period are homosexual.[72] These coercive copulations usually include ejaculation and the mounted bat often makes a typical copulation call consisting of a long squawk.[26] Similarly, in hibernacula of the common noctule (Nyctalus noctula), active males were observed to wake up from lethargy on a warm day and engage in mating with lethargic males and (active or lethargic) females. The lethargic males, like females, called out loudly and presented their buccal glands with opened mouth during copulation.[26]

Vesey-Fitzgerald (1949) observed homosexual behaviours in all 12 British bat species known at the time: Homosexuality is common in the spring in all species, and, since the males are in full possession of their powers, I suspect throughout the summer...I have even seen homosexuality between Natterer's and Daubenton's bats (Myotis nattereri and M. daubentonii)."[26]

Dolphins of several species engage in homosexual acts, though it is best studied in the bottlenose dolphins.[36][pageneeded] Sexual encounters between females take the shape of "beak-genital propulsion", where one female inserts her beak in the genital opening of the other while swimming gently forward.[73] Between males, homosexual behaviour includes rubbing of genitals against each other, which sometimes leads to the males swimming belly to belly, inserting the penis in the others genital slit and sometimes anus.[74]

Janet Mann, Georgetown University professor of biology and psychology, argues that the strong personal behavior among male dolphin calves is about bond formation and benefits the species in an evolutionary context.[75] She cites studies showing that these dolphins later in life as adults are in a sense bisexual, and the male bonds forged earlier in life work together for protection as well as locating females to reproduce with. Confrontations between flocks of bottlenose dolphins and the related species Atlantic spotted dolphin will sometimes lead to cross-species homosexual behaviour between the males rather than combat.[76]

African and Asian males will engage in same-sex bonding and mounting. Such encounters are often associated with affectionate interactions, such as kissing, trunk intertwining, and placing trunks in each other's mouths. Male elephants, who often live apart from the general herd, often form "companionships", consisting of an older individual and one or sometimes two younger males with sexual behavior being an important part of the social dynamic. Unlike heterosexual relations, which are always of a fleeting nature, the relationships between males may last for years. The encounters are analogous to heterosexual bouts, one male often extending his trunk along the other's back and pushing forward with his tusks to signify his intention to mount. Same-sex relations are common and frequent in both sexes, with Asiatic elephants in captivity devoting roughly 45% of sexual encounters to same-sex activity.[77]

Male giraffes have been observed to engage in remarkably high frequencies of homosexual behavior. After aggressive "necking", it is common for two male giraffes to caress and court each other, leading up to mounting and climax. Such interactions between males have been found to be more frequent than heterosexual coupling.[78] In one study, up to 94% of observed mounting incidents took place between two males. The proportion of same sex activities varied between 30 and 75%, and at any given time one in twenty males were engaged in non-combative necking behavior with another male. Only 1% of same-sex mounting incidents occurred between females.[79]

Olympic marmot (left) and Hoary marmot (right).

Homosexual behavior is quite common in wild marmots.[80] In Olympic marmots (Marmota olympus) and Hoary Marmots (Marmota caligata), females often mount other females as well as engage in other affectionate and sexual behaviors with females of the same species.[80] They display a high frequency of these behaviors especially when they are in heat.[80][81] A homosexual encounter often begins with a greeting interaction in which one female nuzzles her nose on the other females cheek or mouth, or both females touch noses or mouths. Additionally, a female may gently chew on the ear or neck of her partner, who responds by raising her tail. The first female may sniff the other's genital region or nuzzle that region with her mouth. She may then proceed to mount the other female, during which the mounting female gently grasps the mounted female's dorsal neck fur in her jaws while thrusting. The mounted female arches her back and holds her tail to one side to facilitate their sexual interaction.[80][82]

Both male and female lions have been seen to interact homosexually.[83][84] Male lions pair-bond for a number of days and initiate homosexual activity with affectionate nuzzling and caressing, leading to mounting and thrusting. About 8% of mountings have been observed to occur with other males. Pairings between females are held to be fairly common in captivity but have not been observed in the wild.

European polecats Mustela putorius were found to engage homosexually with non-sibling animals. Exclusive homosexuality with mounting and anal penetration in this solitary species serves no apparent adaptive function.[85][pageneeded]

Bonobos, which have a matriarchal society, unusual among apes, are a fully bisexual speciesboth males and females engage in heterosexual and homosexual behavior, being noted for femalefemale homosexuality in particular, including[86] between juveniles and adults. Roughly 60% of all bonobo sexual activity occurs between two or more females. While the homosexual bonding system in bonobos represents the highest frequency of homosexuality known in any primate species, homosexuality has been reported for all great apes (a group which includes humans), as well as a number of other primate species.[87][88][89][pageneeded][90][86][91][92][93][94]

Dutch primatologist Frans de Waal on observing and filming bonobos noted that there were two reasons to believe sexual activity is the bonobo's answer to avoiding conflict. Anything that arouses the interest of more than one bonobo at a time, not just food, tends to result in sexual contact. If two bonobos approach a cardboard box thrown into their enclosure, they will briefly mount each other before playing with the box. Such situations lead to squabbles in most other species. But bonobos are quite tolerant, perhaps because they use sex to divert attention and to defuse tension.

Bonobo sex often occurs in aggressive contexts totally unrelated to food. A jealous male might chase another away from a female, after which the two males reunite and engage in scrotal rubbing. Or after a female hits a juvenile, the latter's mother may lunge at the aggressor, an action that is immediately followed by genital rubbing between the two adults.[95]

With the Japanese macaque, also known as the "snow monkey", same-sex relations are frequent, though rates vary between troops. Females will form "consortships" characterized by affectionate social and sexual activities. In some troops up to one quarter of the females form such bonds, which vary in duration from a few days to a few weeks. Often, strong and lasting friendships result from such pairings. Males also have same-sex relations, typically with multiple partners of the same age. Affectionate and playful activities are associated with such relations.[96]

Homosexual behavior forms part of the natural repertoire of sexual or sociosexual behavior of orangutans. Male homosexual behavior occurs both in the wild and in captivity, and it occurs in both adolescent and mature individuals. Homosexual behavior in orangutans is not an artifact of captivity or contact with humans.[97]

Among monkeys[clarification needed], Lionel Tiger and Robin Fox conducted a study on how Depo-Provera contraceptives lead to decreased male attraction to females.[98]

Ovis aries has attracted much attention due to the fact that around 810% of rams have an exclusive homosexual orientation.[9][99][100][101][102] Furthermore, around 1822% of rams are bisexual.[100]

An October 2003 study by Dr. Charles E. Roselli et al. (Oregon Health and Science University) states that homosexuality in male sheep (found in 8% of rams) is associated with a region in the rams' brains which the authors call the "ovine Sexually Dimorphic Nucleus" (oSDN) which is half the size of the corresponding region in heterosexual male sheep.[35] Scientists found that, "The oSDN in rams that preferred females was significantly larger and contained more neurons than in male-oriented rams and ewes. In addition, the oSDN of the female-oriented rams expressed higher levels of aromatase, a substance that converts testosterone to estradiol, a form of estrogen which is believed to facilitate typical male sexual behaviors. Aromatase expression was no different between male-oriented rams and ewes."

"The dense cluster of neurons that comprise the oSDN express cytochrome P450 aromatase. Aromatase mRNA levels in the oSDN were significantly greater in female-oriented rams than in ewes, whereas male-oriented rams exhibited intermediate levels of expression." These results suggest that "... naturally occurring variations in sexual partner preferences may be related to differences in brain anatomy and its capacity for estrogen synthesis."[35] As noted before, given the potential unagressiveness of the male population in question, the differing aromatase levels may also have been evidence of aggression levels, not sexuality. It should also be noted that the results of this study have not been confirmed by other studies.

The Merck Manual of Veterinary Medicine appears to consider homosexuality among sheep as a routine occurrence and an issue to be dealt with as a problem of animal husbandry.[103]

Homosexual courtship and sexual activity routinely occur among rams of wild sheep species, such as Bighorn sheep (Ovis canadensis), Thinhorn sheep (Ovis dalli), mouflons and urials (Ovis orientalis).[104] Usually a higher ranking older male courts a younger male using a sequence of stylized movements. To initiate homosexual courtship, a courting male approaches the other male with his head and neck lowered and extended far forward in what is called the 'low-stretch' posture. He may combine this with the 'twist,' in which the courting male sharply rotates his head and points his muzzle toward the other male, often while flicking his tongue and making grumbling sounds. The courting male also often performs a 'foreleg kick,' in which he snaps his front leg up against the other males belly or between his hind legs. He also occasionally sniffs and nuzzles the other males genital area and may perform the flehmen response. Thinhorn rams additionally lick the penis of the male they are courting. In response, the male being courted may rub his cheeks and forehead on the courting males face, nibble and lick him, rub his horns on the courting males neck, chest, or shoulders, and develop an erection. Males of another wild sheep species, the Asiatic Mouflons, perform similar courtship behaviors towards fellow males.[104]

Sexual activity between wild males typically involves mounting and anal intercourse. In Thinhorn sheep, genital licking also occurs. During mounting, the larger male usually mounts the smaller male by rearing up on his hind legs and placing his front legs on his partners flanks. The mounting male usually has an erect penis and accomplishes full anal penetration while performing pelvic thrusts that may lead to ejaculation. The mounted male arches his back to facilitate the copulation. Homosexual courtship and sexual activity can also take place in groups composed of three to ten wild rams clustered together in a circle. These non-aggressive groups are called 'huddles' and involve rams rubbing, licking, nuzzling, horning, and mounting each other. Female Mountain sheep also engage in occasional courtship activities with one another and in sexual activities such as licking each others genitals and mounting.[104]

The family structure of the spotted hyena is matriarchal, and dominance relationships with strong sexual elements are routinely observed between related females. Due largely to the female spotted hyena's unique urogenital system, which looks more like a penis rather than a vagina, early naturalists thought hyenas were hermaphroditic males who commonly practiced homosexuality.[105][not in citation given] Early writings such as Ovid's Metamorphoses and the Physiologus suggested that the hyena continually changed its sex and nature from male to female and back again. In Paedagogus, Clement of Alexandria noted that the hyena (along with the hare) was "quite obsessed with sexual intercourse". Many Europeans associated the hyena with sexual deformity, prostitution, deviant sexual behavior, and even witchcraft.

The reality behind the confusing reports is the sexually aggressive behavior between the females, including mounting between females. Research has shown that "in contrast to most other female mammals, female Crocuta are male-like in appearance, larger than males, and substantially more aggressive,"[106] and they have "been masculinized without being defeminized".[105][not in citation given]

Study of this unique genitalia and aggressive behavior in the female hyena has led to the understanding that more aggressive females are better able to compete for resources, including food and mating partners.[105][107] Research has shown that "elevated levels of testosterone in utero"[108] contribute to extra aggressiveness; both males and females mount members of both the same and opposite sex,[108][109] who in turn are possibly acting more submissive because of lower levels of testosterone in utero.[106]

Whiptail lizard (Teiidae genus) females have the ability to reproduce through parthenogenesis and as such males are rare and sexual breeding non-standard.[110] Females engage in sexual behavior to stimulate ovulation, with their behavior following their hormonal cycles; during low levels of estrogen, these (female) lizards engage in "masculine" sexual roles. Those animals with currently high estrogen levels assume "feminine" sexual roles.

Lizards that perform the courtship ritual have greater fertility than those kept in isolation due to an increase in hormones triggered by the sexual behaviors. So, even though asexual whiptail lizards populations lack males, sexual stimuli still increase reproductive success.

From an evolutionary standpoint, these females are passing their full genetic code to all of their offspring (rather than the 50% of genes that would be passed in sexual reproduction). Certain species of gecko also reproduce by parthenogenesis.[111]

Jonathan, the world's oldest tortoise (an Aldabra giant tortoise), had been mating with another tortoise named Frederica since 1991. In 2017, it was discovered that Frederica was actually probably male all along, and was renamed Frederic.[112]

There is evidence of same-sex sexual behavior in at least 110 species of insects and arachnids.[113] Scharf et al. says: "Males are more frequently involved in same-sex sexual (SSS) behavior in the laboratory than in the field, and isolation, high density, and exposure to female pheromones increase its prevalence. SSS behavior is often shorter than the equivalent heterosexual behavior. Most cases can be explained via mistaken identification by the active (courting/mounting) male. Passive males often resist courting/mating attempts".[113]

Scharf et al. continues: "SSS behavior has been reported in most insect orders, and Bagemihl (1999) provides a list of ~100 species of insects demonstrating such behavior. Yet, this list lacks detailed descriptions, and a more comprehensive summary of its prevalence in invertebrates, as well as ethology, causes, implications, and evolution of this behavior, remains lacking".[113]

Male homosexuality has been inferred in several species of dragonflies (the order Odonata). The cloacal pinchers of male damselflies and dragonflies inflict characteristic head damage to females during sex. A survey of 11 species of damsel and dragonflies[114][115] has revealed such mating damages in 20 to 80% of the males too, indicating a fairly high occurrence of sexual coupling between males.

Male Drosophila melanogaster flies bearing two copies of a mutant allele in the fruitless gene court and attempt to mate exclusively with other males.[20] The genetic basis of animal homosexuality has been studied in the fly Drosophila melanogaster.[116] Here, multiple genes have been identified that can cause homosexual courtship and mating.[117] These genes are thought to control behavior through pheromones as well as altering the structure of the animal's brains.[118][119] These studies have also investigated the influence of environment on the likelihood of flies displaying homosexual behavior.[120][121]

Male bed bugs (Cimex lectularius) are sexually attracted to any newly fed individual and this results in homosexual mounting. This occurs in heterosexual mounting by the traumatic insemination in which the male pierces the female abdomen with his needle-like penis. In homosexual mating this risks abdominal injuries as males lack the female counteradaptive spermalege structure. Males produce alarm pheromones to reduce such homosexual mating.

Is he/she your service dog? This is a question I hear surprisingly often while Im out on a property working with Bed Bug Detection Canine, Sade. While Im out working with Sade, at home, a rescued golden/labrador retriever mix named Dusty, is well on her way to becoming a Certified Service dog. With experience in both sides, I can personally speak to some of the similarities and differences between the two.

Service Dogs are a type of assistance dog specifically trained to help people with physical disabilities including visual or hearing impairment, mental disabilities such as PTSD (post traumatic stress disorder), and medical alert for those suffering with diabetes, seizures, narcolepsy and even cancer.

Detection Dogs, or sniffer dogs, are trained to detect substances such as drugs, firearms, mold, currency and of course, bed bugs! Some prisons even have dogs trained to detect illicit cell phones in prisons.

Obviously, the main differences lay in their specific functions, what theyre looking for, actions they must perform and behavior (service dogs must be laid back and calm while you want to see a strong working drive in detection dogs), but little else differs.

Either dog can be bred for their specific purpose by organizations, private breeders or even selected from shelters and rescues. The training it takes to get them there is quite similar, taking six to twelve months either way for a completely certified working dog but the end result is the same, helping humans. Is it really any wonder theyre considered mans best friend?

St. John’s is Canada’s 5th most bedbug infested city, says extermination company – CBC.ca

St. John's has made it to the top of another list, but this time it's not for the colourful houses or oceanfront location.

The most easterly city in Canada is also housing a host of unwanted guests bedbugs.

Pest control company Orkin Canada released data gathered from the number of treatments it performed at both residential and commercial properties throughout the country from July 1, 2016, to June 30, 2017.

Toronto topped its list of bedbug ridden cities, followed by Winnipeg, Vancouver, Ottawa, St. John's, Edmonton, Halifax, Sudbury, Scarborough and Calgary.

Bedbugs rely on humans for more than just lunch.

Orkin released its list of the 25 most bed bug-ridden cities in Canada. (Orkin Canada)

"They're great little hitchhikers, and unfortunately we're a great mode of transport," said Ken Penney, service manager for Orkin in St. John's.

"From our luggage, purses, bags, wallets, cell phone casesthese are all the ways we have confirmed bed bugs navigating from one place to the other."

Penney points to the oil boom and a reliance on the tourism industry for St. John'shigh ranking among much bigger cities on the list.

"In recent years we've become an oil-based society and we rely heavily on tourism, hence we inherit the trends that come with those industries," Penney told CBC Radio's St. John's Morning Show.

"Increased tourists means increased hotel capacities, [workers] travelling between job sites, shared quarters, carpooling and disposable income, which also means vacationing, so all of these things are part of the bed bug equation.

"So it has increased, but that's the cost of our lifestyle."

The parasitic insects tend to live and hide in the areas where we sleep, but they aren't limited to hotels and apartment buildings, Penney said. They've been found in buses, taxis, theatres, food courts and offices.

Some people get red, itchy spots when bitten by bedbugs, some show no signs at all, Penney said, so it isn't always obvious there is a problem.

Penney has seen infestations so severe they had to tear out the walls and flooring in a home and throw out all the furniture.

"And the occupants are just there stood up saying, 'I had no signs, I didn't know that this happened,' and we're finding hundreds of bugs in behind almost every obstacle."

This fed, adult bed bug is no bigger than an apple seed. (Sudbury & District Health Unit/www.bedbugsinfo.ca)

Bedbugs can thrive in a spotlessly clean room, and one female bedbug can lay one to five eggs per day, so vigilance is key.

Penney's best advice is to thoroughly inspect the area around your bed, including linens, creases in mattresses and furniture, the box spring, headboard and framed pictures.

Look for insects adults are reddish-brown and about the size of an apple seed eggs, blood stains and fecal matter.

"St. John's is a small city, but it's also one of North America's oldest cities, hence we shouldn't believe we should be impervious to one of North America's oldest pests."

"Not Seen A Bed Bug Since!!"

Hi to all!

I used to travel for a living, and somehow in my travels I picked up bedbugs. After a year of fighting them, I had bugs in the bedroom, in my easy chair, my car, and even my office. I went online and found your website. Since I live nearby, I stopped by and discussed the problem with you.

I bought your basic kit, and used it on everything I came in contact with ONE TIME, and I not seen a bedbug since. Your product definitely works as advertised, and also leaves a pleasant woodsy smell that reminds me of my time in the woods back in Wisconsin.

Since I don't travel anymore, I have gotten a rescue cat from the local shelter, and I think she has ear mites. I have every confidence that Best Ever will help me help my new friend. She doesn't like it much, but I think we will both be happy with the anticipated results.

Thanks for having a product that is effective, natural, non-toxic, and works the way it's supposed to.
