To those who wonder about the 'natural' sexual behaviour of the creatures claimed to be the invention of YHWH, may I recommend Paul Bagemihl's book, Biological Exuberance: Animal homosexuality and natural diversity.
The book is really a meta-study of the natural sexual behaviour of some 400 animal species, in the that the author has read the research of many zoologists and incorporates and refrences their notes in the book. At the end of the comments on different species, you can find the reference to field notes if you wish to study the behaviour.
Here's Amazon's remarks concerning the book:
And indeed it must have been, since most scientists have thus far studiously avoided the topic of widespread homosexual behavior in the animal kingdom--sometimes in the face of undeniable evidence. Bagemihl begins with an overview of same-sex activity in animals, carefully defining courtship patterns, affectionate behaviors, sexual techniques, mating and pair-bonding, and same-sex parenting. He firmly dispels the prevailing notion that homosexuality is uniquely human and only occurs in "unnatural" circumstances. As far as the nature-versus-nurture argument--it's obviously both, he concludes. An overview of biologists' discomfort with their own observations of animal homosexuality over 200 years would be truly hilarious if it didn't reflect a tendency of humans (and only humans) to respond with aggression and hostility to same-sex behavior in our own species. In fact, Bagemihl reports, scientists have sometimes been afraid to report their observations for fear of recrimination from a hidebound (and homophobic) academia. Scientists' use of anthropomorphizing vocabulary such as insulting, unfortunate, and inappropriate to describe same-sex matings shows a decided lack of objectivity on the part of naturalists.
Astounding as it sounds, a number of scientists have actually argued that when a female Bonobo wraps her legs around another female ... while emitting screams of enjoyment, this is actually "greeting" behavior, or "appeasement" behavior ... almost anything, it seems, besides pleasurable sexual behavior.
Throw this book into the middle of a crowd of wildlife biologists and watch them scatter. But Bagemihl doesn't let the scientific community's discomfort deny him the opportunity to show "the love that dare not bark its name" in all its feathery, furry, toothy diversity. The second half of this hefty tome is filled with an exhaustive array of species that exhibit homosexuality, complete with photos and detailed scientific illustrations of the behaviors described. Biological Exuberance is a well-researched, thoroughly scientific, and erudite look at a purposefully neglected frontier of zoology. --Therese Littleton.
