DeBumelich 1964 237 March 10 on board "Golden Bean", Cocos Is. to San Diego, Calif. went out from 7:45 to 9. Beautiful clear, calm weather and a fair number of birds around considering the last few days. Saw 2 Oceanodorus castus (before 8 and 1 between 8 + 8:30 as well as a dark-phase and 3 light-phase Puffinus pacificus. Shortly before these appeared a small, red chocolate-brown shearwater, black beaked, crossed in front of the bow; the wings were held much straighter than in the P. pacificus. The dark bird was either P. griseus or P. tenuirostris, prob. the latter. Between 8:30 and 9 saw 2 more light phase wedge-tail shearwaters. Weather permits twice for emergency drills on board. The birds were passing by singly or in 2s, no groups, and fairly evenly spaced at first. Went to sleep between 9 and 10, then out to 11:30. Between 10 and 10:30 saw 5 (3 in a group, 2 solitary) O. castus, 2 solitary dark-phase and 2 solitary, light-phase Wedge-tail Shearwaters. They have all had the light bar on the greater secondary coverts and all have had this slow wing beat and arched carpals f as noted on the trip down. The other secondary coverts are light-tipped, and the head is dark to the throat (includes thermal region), the color blending. All birds seen were flying along, effortlessly passing the ships. A Sooty Tern passed the ship at this time also. Occ. see something trailing water
