I think that Ive been mostly offwiki for most of the last day including being away from any Internet connection for almost all of the last eight hours   Do for example veterinary textbooks really talk about animals having sexual intercourse a bit of a euphemism by the way intercourse means something like transaction or interaction and sexual intercourse was meant to be a genteel and vague substitute for more direct terms like rutting rather than copulating or mating  That seems unlikely to me  IMO sexual intercourse is used exclusively to describe human copulation or nearly exclusively  if were comparing humans to nonhumans we might well use the human term for all  When describing nonhumans were often more direct I have no objection to having separate articles about human and nonhuman copulation for WPSIZE reasons if nothing else
