Researchers Use Drones to Reveal How Turbulent Tidal Flows Affect Seabirds' Foraging Behaviors

Turbulence caused by natural coastal features and manmade ocean systems has a significant impact on seabird foraging behavior, according to new studies.

He continued, " "The drone gave us a bird's eye view, helping us to follow the terns' extremely dispersed foraging activity and their close interaction with specific flow features. Powerful tidal currents produce upwelling boils and swirling vortices, which can carry possible prey (such as small fish) to the water surface and catch them there. As a result, these physical mechanisms provide terns with foraging opportunities."
