Of course, to determine whether it was gay sex is monumental to prove. You can't ask them if they're involved in gay sex, and any activity observed is open to interpretation as to what they were doing.
But left-wing, liberal scientists had no problem declaring it as gay sex to prove that it occurs in the wild and is considered normal but there is no way to prove it.
My question to you is, how do you know there aren't any gay animals?
I have seen probably a dozen young bulls hop up on another young bull. Never have I seen one insert his penis into the other ones anus. I considered this more of young guys dry humping each other for a moment. Never to ejaculation either. This wasn’t a repeated effort. Just a one time jump amongst the hundreds of young bulls out on the ranch.
So if I had to make a bet II would say there is no such thing as gay animals who are living in their normal terrain.
