Feeding characteristics and prey profitability in five herring-feeding killer whales ( Orcinus orca ) in northern Norway
This study used multisensory data tags with integrated 4K video to investigate feeding behavior and prey profitability in five adult male killer whales ( Orcinus orca ) at herring wintering grounds in Norway, in 2016 and 2017. Video recorded two killer whales engaged in carousel feeding, and two eng...
