aeRODYNAMICS AND HYDRODYNAMICS OF THE ‘HOVERING’ FLIGHT OF WILSON’S STORM PETREL

Wilson’s storm petrel (Oceanites oceanicus) characteristically feeds by’ hovering’ over the water surface, but its technique for this is unlike that ofother flying vertebrates. The kinematics and aerodynamics of this ‘ hovering’flight were investigated to determine the possible sources of lift
