area on September 2k (see Table //6). 
Bristle-thighed Curlew AO B»1 CO DO 
(Numenius tahitiensis ) Number Collected «1 
Five minutes after sunset on September 10, a line of 20 birds , 
probably this species were seen flying high in a southerly direction. This 
maybe the only such sighting of this nature. Three smaller birds 
accompanying the line of Curlews may have been Golden Plovers. The other 
bird recorded was taken as a specimen. 
Sooty Tern A=1^9 B*1007 C-113U D*271 
( Sterna fuscata ) Number Collected *1 
Sooty Tern breeding cycles throughout the study area were generally 
either just finishing or just starting. Concentrations near islands were 
not high and for the most part Sooty Terns were low in numbers and concentra¬ 
tion at sea. The notable exceptionwae several feeding flocks in the 3>°N 
area. On September lh an immense feeding flock was observed atU°27*N; 17l45>li C W.
