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.
