AB  - To understand foraging strategies and behavioral flexibility in wild animals, it 
      is important to evaluate the physiological costs imposed by foraging efforts and 
      how these costs affect foraging and provisioning behavior. Oxidative stress is a 
      possible physiological indicator associated with foraging behavior in wild 
      seabirds, and may also affect their reproductive performance. However, no 
      previous study has simultaneously recorded foraging behavior and the associated 
      oxidative stress in wild seabirds. Using an integrative approach based on 
      oxidative stress measurements and bio-logging techniques (i.e., the use of 
      animal-borne sensors), we determined the relationships between foraging behavior 
      and oxidative stress in chick-rearing streaked shearwaters Calonectris leucomelas 
      in 2018 and 2019. To quantify their oxidative stress, we measured reactive oxygen 
      metabolites (d-ROMs) and biological antioxidant potential (BAP) in their plasma. 
      We found that the d-ROMs levels were positively related to the maximum distance 
      from the colony and the number of takeoffs, especially in 2019 when shearwaters 
      flew further to forage. In 2018, when they flew relatively short distances, the 
      BAP levels were positively related to the levels of their physical activity 
      (overall dynamic body acceleration; ODBA). We conclude that longer and less 
      successful foraging may lead to increase oxidative stress, while successful 
      foraging may mitigate the oxidative stress of foraging by providing dietary 
      antioxidants. Our results highlight that the combined data from bio-logging and 
      oxidative stress measurements aid in evaluating the underlying physiological 
      costs of foraging behavior in wild animals.
