The Saga of the Toronto Gay Penguins

In a bizarre move, a zoo is splitting up a male pair, to force them to breed. 

Queer Politics for the Birds: The Saga of the Gay Penguins

Toronto’s zoo is splitting up a pair of same-gender penguins. These Happy Feet males, Pedro and Buddy -- jokingly referred to as "Brokeback Iceberg" -- have been nesting with each other for a year.

The reason for the boys’ split-up, a zoo official says, is because African penguins are an endangered species.

The pair has what’s known as a "social bond," but it’s not necessarily a "sexual bond," Tom Mason, the zoo’s curator of birds and invertebrates told the Associated Press.
"Penguins are so social they need that...company. And the group they came from was a bachelor group waiting for a chance to be paired up with females," Mason stated. "They had paired up there, they came to us already paired, and it’s our job to be matchmakers to get them to go with some females." 


The argument they have used to justify this, is the old one that they aren't "really" queer, just doing it in the absence of females. This is nothing more than homophobia directed at the animal world, used to avoid facing the fact that sexual activities between members of the same biological sex are commonplace in nature - for some species, and for some individual animals, more common than the heterosexual kind.

Bruce Bagemihl, in Biological Exuberance, has described this avoidance strategy, and several others, in his book "Biological Exuberance" - together with accounts of the extensive scientific evidence now emerging to rebut them.

As scientists, the curators at Toronto zoo really should know better.

"Unnatural" Nature, Immoral Butterflies: The Great Cover-Up of Animal Homosexuality

Back in 2000, an eminent and otherwise respectable biologist declared that except for a few instances observed among primates, there was no evidence of homosexuality among animals:

When animals have access to the opposite sex, homosexuality is virtually unknown in nature, with some rare exceptions among primates."
-G. Barlow, 2000
This was breathtakingly inaccurate. Just the previous year another biologist, Bruce Bagemihl,had published a book summarizing previously published scientific papers which described homosexual behaviour in over 300 species of animals and birds (listing dozens of papers for each), and also listing additional species of reptiles, amphibians, fish and even insects - over a thousand species in all, and tens of thousands of peer-reviewed articles. The first recorded observations of animal homosexuality were two millenia ago, by the ancient Greeks. In modern times, the first formal publication of scientific observations go back over 150 years. Photographic evidence of male swan couples has existed since the mid-nineteenth century.
Even this illustration, of male beetles doing it, was published as long ago as 1896:

The Real Mama Grizzlies: Lesbian Moms?

Sarah Palin, With Bear

Sarah Palin's understanding of wildlife appears to be no better than her tenuous grasp of social history.  Mrs Palin has been very much in the news over her enthusiastic promotion of a band of crazies  thoughtful, conservative candidates who agree with her own views on education and "traditional family values".   The women in this band she likes to describe as "mamma grizzlies", most recntly Christina O'Donnell in Delaware.
The problem with the conservative view of the "traditional" family and its values is that has little relation to history, and is in fact a relatively modern invention. The problem with her adoption of mamma grizzlies as her model is that they too scarcely embody the "family values" she claims to support.  Real life mamma grizzlies do not live or mate in the nuclear families she so admires. Rather, they mate in promiscuous, polygamous groups, then raise their young as single mothers - or in collaboration with other females, as family units headed by two women.  The closest human counterparts to real-life "mamma grizzlies" are lesbian couples, with kids - not exactly Christian O'Donnell.
Consequently, many grizzly mammas raise their young as single parents - unless (as many do) they team up with another female for co-operative parenting.
The two mothers become inseparable companions, travelling and feeding together throughout the summer and fall seasons as they share in the parenting of their cubs.. ....... A bonded pair jointly defends their food, and the two females also protect one another and their offspring (including protecting them from attack by grizzly males). The cubs regard both females as their parents, following and responding to either mother equally; bonded females occasionally also nurse each other's cubs. If one female dies, her companion usually adopts her cubs and rears them as her own.
Sexual activity is not always exclusively for procreation and not always between opposite-sex partners; the partners in procreation are usually opposite-sex (not always - some lizards reproduce from female pairs), but the parties in biological parenting and child-rearing are not always the same; and there are instances where same-sex parents have clear advantages over the alternatives, especially where the alternative is not "one mom and one pop", but a single mother, as in the case of the Grizzlies.

There are thousands of animal species that are known to have homosexual relationships, some even more frequently than heterosexual relationships (for example bighorn rams, female bonobo chimps and male giraffe). Many other animal species, especially birds, form same-sex parenting couples, by adoption or surrogacy. In human societies, there are likewise numerous examples where standard practices include same-sex relationships in addition to opposite sex-marriage - and the evidence from research is that just as in the animal kingdom, same-sex couples are at least as capable of good parenting, and sometimes even better, than opposite - sex couples.

Some Albatross Same- sex Parents

A key part of the argument against homoerotic relationships, fundamental to the Catholic Magisterium, to the religious opposition more generally, and to the supporters of so-called “traditional” marriage, is that same sex relationships are somehow “unnatural”, “against natural law”. This claim is entirely without foundation. What these groups have in common, apart from their conclusion, is a total disregard for the evidence.  Some research into the Laysan albatross neatly illustrates this.  The disregard of the need for evidence does not only apply to claims for natural law: exactly the same charge can be made against Vatican claims that "homosexuals" are motivated solely by  -indulgence, and that homosexual "acts" lead one away from God - claims that likewise do not stand up to scrutiny. For now, though, I am concerned only about the problem as it applies to the argument from natural law
All albatrosses are large birds nesting in isolated colonies free from natural predators, which makes them easy to study (the birds are trusting and allow researchers to get up real close and personal). Much of their behaviour is well-known. For instance, in one colony at Kaena Point, Hawaii, there are about 120 breeding pairs, who gather for mating every November. They form long-term partnerships, and after copulation, lay a single egg, which they incubate in shifts, taking turns to leave the nests for weeks at a time to feed at sea. They form long-lasting, often life- long pairs, and were praised by former US first lady Laura Bush for their commitment to each other, and the example they offered as icons of monogamy. The obvious assumption that these monogamous pairs represent one male and one female in a neat nuclear family, though, turns out to be false. One third of the pairs are female couples, some of whom had nested together every year since right back to the start of data collection – 19 years.
Ornithologist Lindsay C Young  has been studying this albatross colony since 2003, as part of her doctoral dissertation.  She says that the discovery of so many female pairs forced her to question assumptions she didn’t even know she was making.  This in itself was something of a breakthrough: observations of same sex behaviour or relationships in the animal world are not new, but too often in the past, biologists have simply ignored them, or attempted to explain these observations as aberrations.
Joan Roughgarden quotes one notable scholar who claimed in 2000, at the end of a long and distinguished career,  that  “When animals have access to members of the the opposite sex, homosexuality is virtually unknown in nature, with some rare exceptions in primates”.
But just the previous year, Bruce Bagemihl had published a book reviewing published academic research into over three hundred vertebrate species which engage in same-sex courtship and genital contact. In some of these, homosexual activity is even more frequent than heterosexual intercourse.
In the case of the albatrosses though, the female pairs Young studied displayed same-sex relationships – not same-sex activity. They were female couples, conscientious parents, and engaged in just about all the activities together that other couples do – except for physical sexual intercourse. Instead, they would find a male albatross purely for copulation so that they could produce a fertilized egg.
As female pairs, these couples were physically capable of producing twice the number of eggs that other pairs could. Each bird is capable of producing only one egg each year, and so most nests hold only one egg. Yet obrsevers have frequently noted  that some nests contain two eggs, in what the biologists call a “supernormal clutch”. Early attempts at explanations speculated that perhaps some individual brds were after all capable of laying two eggs, or that some inexperienced younger females were inadvertently “dumping” their eggs in the wrong nests.. Harvey Fisher, he researcher who proposed this dumping hypothesis in 1968, after seven years of daily observations, justified his conclusion in part with the observation that “after all, promiscuity, polygamy and polyandry are unknown in this species”.
It simply had not occurred to anyone to consider that the nest might hold two females.
That was until Brenda Zaun, a biologist studying Laysan albatrosses forty years later, observed that year after year, it was the same nests which yielded double eggs. When she sent feathers from a sample of the two-egg breeding pairs and sent them to Lindsay Young  for laboratory DNA sex testing, Young simply disbelieved the finding that every brd was female, and assumed she had erred in the testing procedure.
She repeated the tests, and got the same result.. To be sure, she then went back to the field and sexed every bird in the colony, and found that 39 of 125 nests were of female – female couples: 19 where double eggs ahd been seen, and an additional 20 with single eggs.
This example is not about “lesbian” birds, or about avian “homosexual” intercourse. However, it does illustrate how easily even professional observers have in the past mistakenly applied heterosexist assumptions to their observations, which have led to completely false assumptions. Testing these assumptions against evidence leads to  very different conclusions.
The albatross female couples also illustrate how in the natural world, procreation and pair –bonding can be quite distinct. Albatross pairs, including female couples are monogamous, mutually devoted couples and careful parents: but in some cases, the physical act of copulation is only about fertilizing an egg and nothing more.
Although these albatrosses do not show signs of sexual activity by the female couples, many other species do. Bagemihl listed over three hundred such species in 1999, Joan Roughgarden and, Vasey and Sommer, have since listed many more, across all branches of the animal kingdom.  The evidence is clear: in the animal kingdom, same sex relationships and homoerotic sexual activity are no less “natural” than left-handedness.
This does not in itself make homosexuality morally “right”, but it does show that “natural law” cannot be used to argue that they are wrong. On sexual ethics, the “law of nature” is simply neutral.

Same-Sex Parents, Furred and Feathered.

There have been an increasing number of research studies which show that as parents,  same sex couples are at least as good as opposite sex- couples. As a gay father and grandfather myself, I don’t really need to be told this by modern research: I first learnt of the evidence decades ago, from a family friend who was then a child welfare social worker, and is today a top authority on the subject. I also have the best of all possible authority, the experience of my own family. My daughter is very clear on the subject: she is on record as saying “Gay Parents? I recommend them”. She has told me that when she says a young child with two dads, her immediate response is - “Lucky child”. Still, it’s good to see the evidence getting a more public hearing. and reaching the mainstream.

I was interested though, to find that in this, as in so many other areas, of human sexuality, the same pattern is found in many species of animals and birds.

Two Dads, with Kids
Homosexuality in animals has been known since ancient times, but still fails to penetrate the public consciousness. Nevertheless, researchers are now starting to publicize the abundant evidence for same sex coupling, pair bonding, and parenting. (And contrary to the protestations of Focus on the Family, NOM, et al, these do not always go together, not in humans, not in animals.) The nature and variety of the forms that animal parenting can take is breathtaking, with all the variations found in human society, and more (some of the animal practices would land humans in jail. “Nature” is not all sweet and lovable).

How do same sex couples find their next generation? In many of the same ways humans do, but excluding the turkey baster and in vitro fertilization. Quite often, they were in the same position I was – offspring resulted from an earlier, opposite-sex partnership. For females, Laysan's Albatross and many other birds may use sperm donors, finding an obliging male to copulate with, for the sole purpose of fertilizing their eggs. Male couples may find surrogate mothers: Black Swan male couples may hook up with a female in a menage a trois – then boot her out after the eggs have been laid. Adoption is also common: many species have same sex couples that take on orphaned or lost youngsters. Some couples are rather more cavalier though, and simply kidnap their youngsters – quite literally, in this case. (Don’t try this if you’re human, though.) Just as in human society, some youngsters biological parents who either can’t or won’t raise them themselves – and they may dump them on same sex couples to raise, in nest parasitism.

Are they good parents? Quite often, not only as good, but better. There are many reasons for this. In birds, quite often it is not true that children “need” a mom and a pop. Many species (such as Warthogs, Red foxes and Sage Grouse) are raised by just one parent. When they get two parents, even of the same sex, that is immediately a bonus – they get double the parenting right off. Often, they get better, more spacious homes. Some female bird couples (Greater Rheas, Canada Geese) build what amount to double nests to hold two clutches – but where only one clutch has been fertilized, bingo: a double size home for a standard size family. Some male couples get bigger nests because only the male does the nest-building. Two males = two builders, and again, a bigger home. Other male couples get not so much a bigger home, as a bigger lot. Black Swans use their superior combined size and strength as two males to grab bigger or better territories – and thus better feeding grounds. Mammal youngsters sometimes get better feeding, simply by having to moms to nurse them: some females will suckle their partners’ young - grizzly bear mamma pairs may both nurse and protect each other's young. Then there are the family variations not usually seen in humans. If two parents are better than one, how about three, or even four? Grizzly bears are often raised by female pairs – and sometimes by female trio (The familiar term "gay bears" takes on a whole new meaning).

When sexual activity between males, or between females has been professionally observed, it has too frequently been dismissed or explained away as “deviant”, or the result of “accident”, or even as “immoral” behaviour (as in “A Note on an Apparent Lowering of Moral Standards in Lepidoptera”, the title of a published scientific paper. I kid you not.) In many parts of modern Western culture, there has arisen a deeply held assumption, in spite of all the evidence to the contrary, that the only "natural" form of sexuality and family is "one man, one woman". Even when faced with evidence to the contrary,from the animal world or from human anthropology and history, these people dismiss such evidence as "freakish", or unnatural. In their own observations, their hetero normative assumptions distort the evidence. When one animal is observed mounting another, it is simply assumed that the one on top is male, the other female. And so the myth is perpetuated that only opposite sex mounting occurs.

The plain truth is that in nature, sexual diversity is the norm. (It may well be that what is truly “unnatural” is exclusive heterosexuality . Fortunately, several writers over the last decade have begun to expose the way in which these biases have been distorting scientific research and its dissemination. We will be hearing a lot more about animal same sex relationships and parenting in future - which will help to counter the lies and ignorance propagated by the sexual morality brigade.

Bighorn Rams: Macho Homos, Wimpish Heteros

To look at them, bighorn rams are the very image of hypermasculinity. They live on the rugged mountain slopes of Montana and Canada, in an environment that demands strengh, athleticism and stamina. Their appearance is impressive, with large thick horns curling back behind the ear, and they’re big, weighing up to 300 pounds. They exude so much machismo, that their image has been appropriated by numerous as a symbol for many  male athletic teams. And they like their sex – with other males. Those few who don’t, are described by researchers as “effeminate” .

Lovers, maybe?

For bighorn sheep (and also for thinhorns), "natural" sex is same-sex, including elaborate courtship rituals, genital licking, and anal penetration. (Many rams also find a way to "masturbate" - not with their hooves, but by rubbing on the ground.)  In this "homosexual society", almost all rams routinely participate year-round in sexual activity with each other, but heterosexual intercourse is limiting to the rutting season. Even then, not all rams, especially the younger ones, get to participate.

For Bighorn and Thinhorn Sheep, heterosexuality is definitely not "normal".

From “Evolution's Rainbow: Diversity, Gender, and Sexuality in Nature and People ” (Joan Roughgarden):
“The females live separately from the males. The sexes associate only during the breeding season, from mid fall to early winter. A female is receptive for about three days, and will not allow herself outside of these three days.”
This emphatically does not mean that the males endure sexual abstinence for the rest of the year.
The males have been described as `homosexual societies`. Almost all males participate in homosexual courting and copulation. Male-male courtship begins with a stylized approach, followed by genital licking and nuzzling, and often leads to anal intercourse in which one male, usually the larger, mounts the other. The mounted male arches his back, which is identical to how a female arches her back during heterosexual intercourse. The mounting male ahs an erect penis, makes anal penetration, and performs pelvic thrusts leading to ejaculation. 
The few males who do not participate in male sex are described as “effeminate”,. These males are identical tin appearance to other males but behave quite differently. They differ from “normal males” by living with the ewes rather than joining the all-male groups. These males do not dominate females, are less aggressive overall, and adopt a crouching, female urination posture. These males refuse mouning by other males. These nonhomosexual males are considerd “aberrant”, with speculation that that some hormone deficiency must underlie their behaviour. Even though in physical appearance, including body size and horn development, these males are indistinguishable from other males, scientists urge further study of their endocrinological profile.
This case turns the meanings of normal and aberrant upside down. The “normal” macho bighorn has full-fledged anal sex with other males. The “aberrant” male is the one who is straight – the lack of interest in homosexuality is considered pathological. Now, why would being straight be a pathology, requiring a hormonal checkup? According to the researchers, what’s aberrant is that a macho-looking bighorn ram acts feminine! He pees like a female – even worse than being gay.
(Same sex mountings have also been described in several other species of sheep and goats in North America and Europe, and in farm animals).

Exclusive Heterosexuality Unnatural?

"I don't know of any species that is exclusively heterosexual"
- Zurich Zoo tour guide, Myriam Schärz.
The argument that same -sex relationships are supposedly "unnatural" is so fundamental to the homophobes' case, that it needs to be countered at every opportunity. At Bilerico Project, Jesses Monteagudo has a good rundown of just how widespread same sex behaviour is in the animal kingdom. Here are some extracts:
