However, the fact that really made it all special was the revelation that the mating call of a male tapir is not, as I had speculated, some variant on "Gronk, baby," but could be approximated by saying "Eeeka-eeka!" in a high squeaky voice. (Go on, try it. I won't tell. I said it a few dozen times myself. It must've sounded like I was watching tapir art films in here or something.)
This is not something I had known, or indeed, had ever hoped to know, but of course, as soon as I learned it, I couldn't resist the urge to share the haunting and majestic booty-call of the tapir with everyone I know.
