Lehner, P. 1964 Oct. 7 last crossing International Date Line Oct. 8 up at 5:45 A.M.; besides crossing the Date Line we also gained 1 hour last night, at 7:00 A.M. a Red-tailed Tropicbird approached the ship, circled and then flew about 300 yards off the port side where it fed; I observed it making 3 dives from a height of about 80-100 ft. - it did not drop straight down but side-slipped like a goose, possibly controll its fall to intercept a moving fish; a plankton sample was taken with the sled at 5:25 P.M.; it rained during the period the sample was being taken; late afternoon Huber shot a Cook's Petrel - I think he was more amazed at hitting the bird than the bird was at being shot.
