Windscapes shape seabird instantaneous energy costs but adult behavior buffers impact on offspring
International audience Background: Windscapes affect energy costs for flying animals, but animals can adjust their behavior to accommodate wind-induced energy costs. Theory predicts that flying animals should decrease air speed to compensate for increased tailwind speed and increase air speed to com...
