Threshold foraging behavior of baleen whales
The authors conducted hydroacoustic surveys for capelin Mallotus villosus in Witless Bay, Newfoundland, on 61 days during the summers of 1983-1985. On 32 of these days they observed a total of 129 baleen whales, including 93 humpback Megaptera novaeangliae, 31 minke Balaenoptera acutorostrata and fi...
