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.

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:
