February 1965 BCF Brown Booby Twelve of the 13 birds seen in February were within sight of Oahu. The thirteenth was seen at 16°N 154° W, 200 miles from nearest land. All were adults. Red-footed Booby All but one of the 106 birds seen in February were adult birds, and were within sight of Oahu. The exception was an immature, seen at the same location as the exceptional Brown Booby. The two birds appeared about five minutes apart but stayed in the vicinity of the ship long enough to fly off together. Great Frigatebird A negligible decrease from 19 birds in January to 15 in February was recorded. The species tended to have a more northerly distribution this month. Sooty Tern A 34% decrease from 2354 in January to 1796 in February may possibly be of significance. As in previous months greatest concentrations were observed in the southeastern corner and around the high Hawaiian Islands. Except in these two areas, fewer larger flocks were recorded. Many immature birds were seen in the south, but all northern birds were adults. Noddy Tern Of 167 birds seen in February, eleven were seen in a flock just over 100 miles south of Oahu. The remainder were seen within sight of Oahu.
