TSAVO WEST NATIONAL PARK, Kenya—When it comes to darting elephants from helicopters and fitting heavy GPS tracking collars around their massive necks, “a lot of things can go wrong,” David Daballen says. “An elephant can fall on its chest. Imagine, a six-ton animal just sitting on its chest—they crush their lungs.”
As dawn breaks, Daballen, who works with Save the Elephants, is leading a collaring team of a couple dozen people, including nine Kenya Wildlife Service rangers dressed in camouflage and brandishing rifles. They are equipped with a Cessna, a helicopter, and a caravan of Toyota Land Cruisers and other SUVs.
The Cessna, circling overhead, spots an elephant and radios the team. Within seconds the chopper swoops in low, disappearing behind the bushes and trees. A moment later it swoops upward, and the vehicles race toward the spot. Lying on his right side is a bull. His skin is brown and rough, with pokey black hairs.
The team sets immediately to work unrolling the collar onto the elephant’s neck and attempting to tug it underneath. Someone pours water on the animal’s side to keep him cool. Another puts a small stick into the tip of his trunk to keep the airway open.
After struggling 20 minutes to get the collar on, Daballen uses a socket wrench to tighten the two ends together. The job done, a man injects an antidote to wake the animal up, and the team hurries to their vehicles. Everyone is silent as they watch the bull rise. He stands, looks toward the vehicles, then he turns and walks swiftly in the opposite direction.
The bull was the first of 10 elephants the team tranquilized over a week to fit with tracking collars. Their mission: to see how well Tsavo’s estimated 12,000 savanna elephants traverse a new rail line that has recently split their habitat in two. It is the first time in history, Daballen’s organization believes, that elephants are being collared specifically to study how they interact with human infrastructure.
