Pelagic Survey 
Honolulu to San Francisco 
18-28 April 1966 
Observations were conducted by R.L. DeLong between Oahu and San 
Francisco from l8 to 28 April'11966. 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, ^mall numbers of Sabine Gulls, Arctic Terns, 
and Pomarine Jaegers in migration were observed.
