ACS/LA GRAY WHALE CENSUS AND BEHAVIOR PROJECT Updated: 23 JAN 2008 Spotters also detail migratory behaviors observed, including breaching, spyhopping, rolling, courtship, apparent nursing, possible feeding, and interaction with kelp and with other marine mammals. Participants also note possible human impacts on gray whales, including boat interactions, possible harassment incidents, and entanglements. In addition, we identify and record behaviors of any other marine mammals that utilize these waters, including common dolphin, Pacific bottlenose dolphin, Pacific white-sided dolphin, Risso's dolphin, northern right whale dolphin, killer whales, false killer whales, pilot whales, Dall's porpoise, sperm whales, minke whales, humpback whales, blue whales, fin whales, California sea lions, harbor seals, northern elephant seals, and southern sea otters. When possible, attempts are made to cross-check and augment notes on individually identifiable cetaceans with photos and behavior data collected from commercial and private whalewatching boats.
