R. DeBenedictis 1964 11 Jan on board Golden Bear off Channel Islands, Calif. by 12:50, 3?, (ad, 2 imm) KiHiwakes, 1 Black- footed Albatros following the boat. The gulls, which seemed to have dropped off, were back but all are Hearings, except 1 or 2 Calif. by 1:00 2 imm + 3-5(?) KiHiwakes went by, Most still going N. About 1:05 went up a group of 6-8 immos. all together + 2 or so separate, and by 1:10 albatros was gone: 1-2 more KiHiwakes + 1 Peifferius (grisens type) From 12:05 + 1:10 ( hours observation): 54 KiHiwakes; 1 Alcicd, 3 Fulmar, 1 Pefferius, 1 Bonaparte Gull; 15-25 Larus sp. (argentatus type). Stayed out until about 2. From above 1:30 on ran in to large #s of KiHiwakes, up to 20 in sight at once, and probably about a total of 50. almost all (c. 95%) were immatures, just flying slowly by. The large groups were feeding on the water, not much competition for food and none of the gyralism that New gulls showed in S.F. Bay. All quiet. The large groups were not severely moving, but most of the single birds were doing? North. Saw one more dark Fulmar, and by 2 P.M three Black foote (1 white-veiled Phase, 2 all dark phase) were following its boat. The gulls stay with the boat for a while, then drop back to feed & come on again. The
