Drones: An ally in the sky to help save elephants

They say an elephant never forgets—and it turns out they can learn to adapt to drones. Once seen as a source of alarm, drones are now proving to be surprisingly elephant-friendly and a valuable research tool. Previously, the use of drones in elephant conservation has mostly relied on their power to disturb: elephants reliably run from them, making them a useful tool to drive elephants from croplands.
