    Behavioural responses of humpback whales to food-related chemical stimuli 
    Bouchard, Bertrand; Barnagaud, Jean-Yves; Poupard, Marion; Glotin, Hervé; Gauffier, Pauline; Torres Ortiz, Sara; Lisney, Thomas J.; Campagna, Sylvie; Rasmussen, Marianne; Célérier, Aurélie (Public Library of Science (PLoS), 2019-02-26)
    Baleen whales face the challenge of finding patchily distributed food in the open ocean. Their relatively well-developed olfactory structures suggest that they could identify the specific odours given off by planktonic prey such as krill aggregations. ...

    Do foraging methods in winter affect morphology during growth in juvenile snow geese? 
    Jónsson, Jón Einar; Afton, Alan D. (Wiley-Blackwell, 2016-10-05)
    Physical exertion during growth can affect ultimate size and density of skeletal structures. Such changes from different exercise regimes may explain morphological differences between groups, such as those exhibited by lesser snow geese (Chen caerulescens ...

    Gannets are not attracted to fishing vessels in Iceland—potential influence of a discard ban and food availability 
    Clark, Bethany L; Vigfúsdóttir, Freydís; Jessopp, Mark J; Burgos, Julian M; Bodey, Thomas W; Votier, Stephen C (Oxford University Press (OUP), 2019-12-04)
    Fisheries produce large amounts of waste, providing food subsidies for scavengers. Discards influence seabird movement, demography and community structure, but little is known about seabird-fishery interactions where discarding is banned. Here, we ...

    Leave or stay? Video-logger revealed foraging efficiency of humpback whales under temporal change in prey density 
    Akiyama, Yu; Akamatsu, Tomonari; Rasmussen, Marianne; Iversen, Maria R.; Iwata, Takashi; Goto, Yusuke; Aoki, Kagari; Sato, Katsufumi (Public Library of Science (PLoS), 2019-02-05)
    Central place foraging theory (CPF) has been used to predict the optimal patch residence time for air-breathing marine predators in response to patch quality. Humpback whales (Megaptera novaeangliae) forage on densely aggregated prey, which may induce ...
