Pelagic Survey Honolulu to San Francisco 18-28 April 1966 Observations were conducted by R.L. DeLong between Oahu and San Francisco from 18 to 28 April 1966. Nine hundred and twenty miles were covered during 101.9 hours of diurnal observation. A total of 578 birds was observed. Weather was favorable until late on the 25th. A gale was then encountered and seas were heavy until we reached the coast. There was little northward migration of Procellarids. The 67 Sooty Shearwaters seen between Oahu and the Coast probably represent late spring migrants. Small numbers of Sabine Gulls, Arctic Terns, and Pomarine Jaegers in migration were observed.
