Drones reveal Antarctic whale 'acrobatics'
The use of drones to capture footage of humpback whales in the Antarctic Peninsula has provided valuable insights into the feeding behavior and conservation of these majestic creatures. The footage revealed a humpback whale using its four-metre-long fin to create a net of bubbles to trap krill, a technique known as 'bubble-netting'. This unique feeding behavior can only be observed in detail from the air, highlighting the importance of drone cameras in studying whale behavior. In addition, the aerial view provided by drones has shed light on the recovery of whale populations in areas where they were previously hunted to near extinction. For example, drone footage off the coast of South Georgia showed the first footage of a mother-calf pair of southern right whales, indicating that these populations are slowly recovering. However, drones have also revealed concerning trends, such as the shrinking of some whale populations, possibly due to climate change affecting their food supplies. The use of drones has opened up new avenues for researchers to monitor and understand the behavior and conservation of whales.
