TEENS 
Sooty Terns increased#' in number as we proceeded from Oahu to the grid. 
Over six times as many as last #uly were recorded in this protion of the 
crui 
Large numbers, including many immatures, were again encountered south 
of Lisianski. Just east of Oahu one bird was observed sitting on the water 
for over thirty seconds. It then flew from the water and joined others 
which were flying along. 
Gray-backed ~JTe rns, Noddy terns and Fairy Terns combined made up 
approximately 9 percent of all terns observed. Most of these were 
encountered through the Leeward Islands. The two species of Noddy 
Terns (H&wiian and Common) usually were encountered in ’respective 1 
flocks or forming mixed flocks. In comparison, the Fairy Tern was 
often observed singly or in tv/os and tended to range faz’ther from land 
than did either of the Noddies. 
TKOPICBIEDS 
The Ned-trailed Tropicbird outnumbered the White-tailed by over 
three to one throughout the at-sea area. Red-flailed Tropicbirds were 
also more likely to be seen at farther distances from islands. Both 
species appear to be attracted to the ship moreso than aUh'other species 
in the area. 
BOOBIES 
Red-Mooted Boobies were approximately four times as numerous as 
either the Blue-iced or the Brown . Most individuals were seen through 
the Leeward chain from the 22nd through the 24th. All others, except 
for a few Red-^poots at sea, were within the Lisianski-Laysan complex. 
All species were found in much greater numbers than last July. 
FRIGATSBIRDS 
Frigatebird numbers were over twice as great as last July. Usually 
individuals were seen, but occasionally two or more ’would follow a 
large mixed feeding flock. 
Frigatebirds were seen to attack Boobies
