Oregon State University researchers have found a new way to study Pacific gray whales’ feeding habits using drones. By capturing aerial footage of the whales as they feed, researchers can gain valuable insights into their behaviors and feeding patterns.
The study, led by Dr. Leigh Torres from the Marine Mammal Institute at Oregon State University, utilized drones equipped with cameras to record the whales as they fed on tiny shrimp-like creatures called mysids. The footage allowed researchers to observe how the whales position their bodies while feeding and how they interact with their prey.
The researchers discovered that the whales use a strategy called “skim-feeding,” where they swim with their mouths partially open to catch the mysids. This behavior is crucial for the whales to efficiently feed on the abundant mysids in the waters off the Oregon coast.
The use of drones in this study provides a non-invasive way to monitor the whales’ feeding behavior without disturbing them. This innovative approach allows researchers to gather data that was previously inaccessible, providing a more comprehensive understanding of the feeding habits of Pacific gray whales.
Dr. Torres and her team hope that their research will help inform conservation efforts for the endangered species. By studying how whales feed and interact with their environment, researchers can better assess the threats facing these majestic creatures and develop strategies to protect their habitats.
Overall, the use of drones in studying Pacific gray whales’ feeding habits represents a significant advancement in marine mammal research. By combining technology with traditional fieldwork, researchers are able to unlock new insights into the behavior and ecology of these iconic marine mammals.
