Close Encounters: Reading Wildlife on Expedition

Marcus Osei · May 20, 2025 · 7 min read

The lioness was watching us for eleven minutes before anyone in the vehicle noticed her.

She was in the shade of a croton thicket, fifteen meters from the track, lying flat with her chin on her forepaws. The grass between us was short — we were not hidden from each other. She had simply decided we were uninteresting. She was waiting for the zebra herd that had moved through the area ten minutes before us.

I watched her watch the zebra. The group watched her. Nobody spoke.

This is what safari actually is: the patient reading of a landscape that is conducting its own business regardless of your presence.

The Binocular Habit

Most people use binoculars reactively — they see an animal, then pick up the glass. The better approach is preventive scanning.

In the Serengeti, every ten minutes, I do a full 360 scan of the visible terrain: tree lines, grass margins, waterhole edges, the raised termite mounds that large cats use as observation posts. What I’m looking for is not animal shapes but behavioral anomalies.

A vulture circling is old news. A vulture descending steeply, wings set, losing altitude fast, is information — there is a kill within 500 meters that the vulture has just decided to commit to.

A herd of zebra grazing is background. A herd of zebra with heads up, feet still, all facing the same direction, is something actively reading a threat.

The landscape speaks continuously. You learn its grammar through repetition.

The Elephant Question

Every first-time safari guest eventually asks: How do you know if an elephant is dangerous?

The honest answer is: you learn the difference between a demonstration and a charge.

A demonstration is noise. The ears spread, the trunk curls, the elephant may take a step or two forward. This is communication: you are too close and I am registering my displeasure. The appropriate response is to stop, reduce your visual profile (get down in the vehicle), and wait. Most demonstrations end with the elephant turning away.

A true charge is different. Ears flat. Trunk straight down or tucked. No noise — or a low rumble you feel more than hear. Full speed.

In twelve years, I have witnessed three true charges. In each case, the vehicle was in an inappropriate position — between a mother and calf, or blocking an established path. The response was to move immediately and fast.

The key detail: we were in vehicles. On foot encounters with elephants require an experienced walking guide and are conducted differently. The distances involved are larger. The decision tree is different.

On Ethical Distance

There is an invisible line in wildlife photography — the point at which your presence changes the animal’s behavior.

If the animal looks at you, that is fine. If the animal moves because of you, you have crossed the line.

The responsibility for staying on the right side of that line belongs to the guide, not the photographer. I have ended photo opportunities many times because the pressure from multiple vehicles was beginning to push an animal. It is not a popular decision. It is the right one.

An animal on the Serengeti that associates vehicles with disturbance changes its behavior permanently. The next group will have a worse experience. The group after that, worse still. The calculus is long.

We are asking the wilderness to remain wild enough to be worth visiting. That requires something from us in return.

The Encounter That Changed How I Guide

Eight years ago I had a group on the crater floor at Ngorongoro. Late afternoon. A black rhino — rare, typically solitary, usually invisible — came around a euphorbias stand and stood forty meters from our vehicle.

The rhino stood. We sat. Nothing moved. I turned off the engine.

For four minutes, the rhino looked at the vehicle. Then it turned slowly and walked back into the scrub. Gone.

On the way out, one of the guests — a pediatric surgeon from Cape Town — said: “In forty years of living, I have never felt so completely irrelevant. That was the best thing that has ever happened to me.”

I understood exactly what she meant. The rhino did not need us. It was not performing for us. It simply passed through a shared moment and returned to its own world.

That is the encounter worth traveling for. Not the dramatic kill, not the number of species ticked off a list — the moment when you realize you are a guest in someone else’s home.
