Drones are now being used to study bird songs

While companies like Amazon, Flirtey, and Zipline continue to use drones for deliveries, a group of ornithologists at Gettysburg College in Pennsylvania have studied a different way to use unmanned aerial vehicles (UAVs).
By suspending a “simple, lightweight recorder” below a DJI Phantom 2 quadcopter drone, Gettysburg College environmental studies professor Andrew Wilson and two undergraduate students studied songbirds and published their results in The Auk: Ornithological Advances.
