Cetaceans of the Channel Islands National Marine Sanctuary / prepared for National Oceanic and Atmospheric Administration, Channel Islands National Marine Sanctuary and NOAA, National Marine Fisheries Service by Stephen Leatherwood, Brent S. Stewart, Pieter A. Folkens. Whales California Channel .r.^'WiF 1 ii.*. Shore observers at San Miguel Island report frequent observations of groups of humpbacks, mostly northbound whales, from late June through September. These groups often include females and young of the year. At this time of year, humpbacks often approach very close to the kelp beds, as did a single animal off the south shore of San Nicolas Island in July 1984. Aerial and vessel surveys of the SCB conducted for the Naval Ocean Systems Center, (1968-1978), and for the Bureau of Land Management, (1975-1978) resulted in 33 observations of humpback whales, distributed by season as follows: qtr 1 (7); qtr 2 (7); qtr 3 (10); qtr 4 (9). Aerial and shipboard observers working in the SCB since 1978 have noted concentrations of humpbacks off the three largest of the northern islands including at least one occurrence each quarter near Adams Cove, San Miguel Island. Further, observations of feeding, often evidenced by large flocks of feeding birds, in March, May, June, July, August, September, November and December, dem- onstrate that not all humpbacks are simply passing through the area. One can only speculate whether the component(s) of the popula- tion using the SCB, particularly waters of the CINMS, will increase proportionate to the growing population overall. Eastern Pacific humpbacks are known to feed on anchovies, krill, pelagic crabs, sardines, cod and even salmon in different parts of their range. In other areas where humpback whales and net fisheries overlap, humpbacks are frequently entrapped or entangled, in wiers, nets, traps and fishing rigging. During Christmas week 1984 personnel from the Santa Barbara Musuem of Natural History found two humpb
