De Benedicti 1964 242 March 12 on board "Vortlem Ben", Coco Is. to San Diego, Calif. Times). From 3:30 to 4 saw only 1 masked Booby, and 6-8 Porpoises which stayed too low in the water [illegible] due to unable to see any of them. The next half hour was a little more wide. After dark a dark phase Wedge-tail shearwater and a Masked Booby went past the bow, it was fairly quiet for a while. (The shearwater may be told by flight only by the wing position + vs. + from the similarity colored, and [illegible] similarly flying dark Sula sula). A school of Porpoises far ahead had many birds over it, which I could not figure out. As we approached they became more and more puzzling, united we were upon the boat. Most of them were Parasitic Jaegers, possibly with 1 or 2 long tails. (not actual cutani) mixed in, and about a third of the remainder were dark and semi-intermediate phase (pale, not white belly) Red-footed Boobies, those flock totaling about 80-100 birds. Additionally there was an adult and aft [illegible] immature Masked Booby (white below, brown above with a faint collar, dark bill + facial skin), a light-phase Wedge-tail Shearwater, and an all dark Puffinus (sp?), plus a dense group of 150+25 and 25-30 scoters (Northern) Phalaropes. The large birds were circling over the porpoises and only the boobies appeared to be diving. The Jaegers were not chasing the Boobies, but may have been working over the Phalaropes, which were
