There’s something I’ve always found mesmerizing about watching animals in the wild.

They have the most incredible instincts, honed from countless generations of survival against constant threats.

Animals have a keen sense of danger. They know immediately when something doesn’t feel right, and they act on it without hesitation.

I saw an incredible example of this last year when I was visiting a remote wildlife reservation in Zimbabwe.

It was late in the afternoon on a hot summer day, and my friends and I were ensconced in a hidden observation bunker situated on the edge of a water hole.

The animals all began to arrive, one species at a time, to cool off before nightfall. First the elephants. Then Rhinos. Zebras. Giraffes. Baboons.

It was a playful mood; all the animals seemed to be enjoying the water, when without warning, there was a stillness. The gazelles froze. The zebras’ ears perked.

Something wasn’t right. A smell. A sound. Something.
