Although spotted hyenas are notoriously difficult to sex, my students and I are typically very good at determining the sex of hyenas using a variety of subtle morphological cues as they move around or engage in “greeting ceremonies” with one another. However, every once in a while a hyena fools us, and an individual believed to be a male for two or three years one day shows up nursing cubs at the den! None of us had ever been able to sex Dionysus with complete certainty, even though this animal will be 2 years old in a few weeks. We had all thus been looking forward to darting Dionysus because we expected this animal would be easy to sex once we could examine it very closely. However, this time, even after the animal fell asleep and we rolled it over so we could examine its genitalia, we continued to get mixed messages.
