January 9--Pacific Ocean, 7th day out Oahu, Grid Area 1 seen at 0545 this morning. January 15--Pacific Ocean, 13th day out Oahu, Johnston I. at 0230 1 bird at 0653 flying south 50-100'. January 17--Pacific Ocean, 15th day out Oahu, ca. 2 days NE Johnston Two feeding flocks observed today, 1st flock at 1329 had 50+ Sooties, 8 Fairy Terns and 1 Masked Booby. This flock was feeding in the middles of a heavy rain squall. No flying fish were observed. The second flock at 1400 had 20 Sooties, 1 Fairy Tern, and 2 Wedge-tails. This flock was feeding at edge of a rain squall (same one as above) but was sometimes out of it and sometimes inside it. As above no flying fish were observed. Watching two birds flying together in light rain both were flying low over the water. They began a series of movements as follows: Abruptly they would pull slightly up in the air and hesitate for a few seconds. While hesitating they would fluff out their feathers and shake their whole body at the same time. This was done 3 times by one bird and 2 times by the other. Since it was raining lightly and this act was repeated it would seem as if appeared to the observer that they were bathing rather than shaking off excess water. January 18--Pacific Ocean, 16th day out, ca. 100 miles SW Oahu 157 birds seen today. 3 feeding flocks, 1 of 85+ birds and one of 26+ birds and one of 25+ birds One non-feeding group of 15+ birds.
