Impact of changing wind conditions on foraging and incubation success in male and female wandering albatrosses
International audience 1.Wind is an important climatic factor for flying animals as by affecting their locomotion, it can deeply impact their life-history characteristics. 2.In the context of globally changing wind patterns, we investigated the mechanisms underlying recently reported increase in bod...
