The sprawling, semi-arid savannah of the fictional "Kalo Game Reserve" in East Africa. A research station run by Dr. Lena Neema, a behavioral ecologist, and Dr. James Tembo, a wildlife veterinarian.

They treat Kip with a single long-acting cobalt bolus (a slow-release pill placed in the rumen) and a Vitamin B12 injection. Within 48 hours, Kip is grooming, rejoining the herd, and standing alert. The head-rubbing ceases.

She recalls a forgotten paper: "Geophagy and micronutrient cycling in ungulates." Termite mounds are rich in minerals. But why only young males? And why the head-rubbing?

Kip becomes the station’s mascot, often found lounging near the lab, watching new veterinary interns arrive. And Lena teaches them the moral of the story: Before you treat the disease, understand the behavior. And before you judge the behavior, listen to the landscape.

But why the termite mound? Termites concentrate cobalt from deep underground, bringing it to the surface in their mounds. And why young males? Young male impalas are at the bottom of the social hierarchy. They’re often pushed to the edges of the best grazing lands—lands depleted of cobalt due to overgrazing.
