Ship Survey of Santa Cruz, Santa Rosa, and San Miguel Islands (cont'd) Surf Scoters, 9 Red Phalaropes, 45+ Western Gulls, Herring Gulls, 600 Bonaparte's Gulls, 1 Pigeon Guillemot in winter plumage, a Xantus Murrelet and 6 alcid sp. Off Santa Rosa over 300 Sooty Shearwaters passed in a steady stream. There were sightings of a Brandt's Cormorant, 9 Red Phalaropes, Western and Herring Gulls, 8 Bonaparte's Gulls and 1 Pigeon Guillemot. Approaching San Miguel, Sooty Shearwaters streamed by with over 1,000 counted. Three Black-footed Albatross, 6 Pelagic Cormorants, 10 Pigeon Guillemots, and 2 unidentified jaegers. Prince Islet, San Miguel, supported at least 800 cormorants and 250 Western Gulls. On the return trip to the Santa Cruz anchorage, we cruised the north side of Santa Rosa and Santa Cruz where over 5,000 Sooty Shearwaters were counted.

San Nicolas Island 5 - 7 April 1968 Itinerary: Arrive: San Nicolas Island 1630 5 April, via Mercer Airlines. Depart: San Nicolas Island 1430 7 April, via M/V Sioux City. Introduction: The short stay on the island was devoted to work on two animals, the Western Gull (Larus occidentalis) and Northern Elephant Seals (Mirounga angustirostris). The gulls are of interest as we will later do a complete study on their ecology, and the Mirounga were surveyed in order to obtain data on the success of the tagging of this species on 4-5 March this year.
