The issue with finding homosexual behaviour in animals is that it’s never exclusive. Homosexual animals tend to be bisexual at best, and can often be chalked up to erroneous mating.
A lot of these studies are used to validate human homosexuality and harm the “it’s unnatural!” argument touted by conservatives. However using a Call to Nature is fallacious, and could be used to validate all number of animal behaviour.
Never is a strong word when that’s just not true
An animal model of spontaneous exclusive homosexuality has however been described in sheep. About 8% of the males in a population studied in the western United States were shown to mate exclusively with other males, even when the choice was given between a male or female partner (Perkins and Roselli, 2007; Roselli et al., 2011b).
I’m guessing most animal behaviorists have priorities other than watching who is fucking whom. Unless we’re talking long-term bonding pairs, which are much easier to observe, but those are not the norm in the animal kingdom.
No, the world and by extension science are just full of homophobia and strict, phantastical, expectations of what sexuality should look like.
