Summary: | The author made observations of the distribution of sea birds, plankton, and baleen whales in the Bering Sea during a 1955 expedition on the R/V NERPA. The high coincidence of all three in time and space results from the plankton (Calanus plumchrus, C. cristatus, and Thysanoessa raschii) forming a common food for birds and whales. Concentrations of marine birds (principally Puffinus griseus, P. tenuirostris, Diomedea immutabilis, and D. nigripes) are prime indicators to whalers of plankton masses and feeding baleen whales.
