January 1965 - BCF cruise Red-tailed Tropicbird This species remained at its low winter level in the area; eight birds were seen. Five of these were at the extreme southern end of the area. White-tailed Tropicbird Numbers declined to 9 from 17 in December. These were distributed widely in the middle and northerly parts of the area; none were seen in the south. Blue-faced Booby Three were seen in January, all between 14°N and 16°N. All were sub-adult birds. A small number of birds apparently come regularly to the southern part of the area during the winter months. Red-footed Booby All 22 Red-footed Boobies seen in January were adult white phase birds. All were within 50 miles of Oahu. Brown Booby The four birds seen in January were all within sight of Oahu. All were adults. Great Frigatebird Ten of the 19 birds seen in January were observed within sight of Oahu. Most of the remaining birds were observed in the southern part of the area. Sooty Tern Numbers of this species rose sharply from 566 in December to 2354 in January concurrent with the start of breeding activity in the Oahu area. Two density centers were apparent; one within 200 miles of the high Hawaiian Islands, and a second at the southern end of the area.
