Sooty Tern 
Sooty Terns were observed mainly during the first five days of the 
trip. Their greatest density was on the 5th of June, when we were 
passing to the south of Sand-Johnston. The Sooty Terns not in flocks 
in this area, appeared to be either heading away from the island or 
towards it. Most of the terns seen were in feeding flocks which were 
feeding on small flying fish, small half beaks(?) and small needle 
fish (?) which were abundant in the area. All of the Sooty Terns seen 
in this area, as well as all others seen on this trip, were adults. 
All of them had short tails which indicates they were probably past 
breeding. 
On the 5th of June, 66 adult Sooty Terns observed to definitely 
have orange streamers. Most of the streamers were new and showed up 
very well. Some of the streamers were old and faded out. These did 
not show up except at close range. There were probably many more streamers 
birds in the area, but they were not observed because of the streamers 
being old and faded or the distance was too great. 
No more definite Sooty Terns were seen in the daytime until the 
2Uth of June when we were west of Eniwetok Atoll, heading for Guam. 
At 1500 on the 9th of June, UOO tern species were sighted flying high 
towards a rain squall. In all probability, these birds were Sooty 
Terns unless there is some other tern that will travel as high as these. 
At present, I am not familiar with any. On the 2Uth of June, 5 adult 
Sooty Terns were observed® These birds were travelling in no particular 
direction. These birds were all adult and they had short tails. 
On the night of June 9th and 10th, Sooty Terns were heard and seen 
around the ship. This was the night before Majuro Atoll was visited. 
No Sooty Terns were seen on this atoll. 
Caution must be used in this area when identifying terns by sound 
at night. There is at least one call of the Black-naped Tern that is 
very similar to one of the night calls of the Sooty Tern. 
Common Noddy Tern 
Common Noddy Terns were seen almost entirely around the islands. 
Numbers of these birds increased the further west we went. The greatest 
density observed was on the 13th of June when we were around Kwajalein 
Atoll. On this day, lli98 birds were seen. Most of these birds were 
seen in flocks, either feeding or sitting on the water. On Majuro, 
Kwajalein, Eniwetok and Guam, the Common Noddy Tern appeared to be one 
of the predominent species present. 
On the 5th ©f June, when we were near Sand-Johnston, 62. ef this 
species were seen. Three of them were orange-streamered. Two had new 
streamers and one had an old one. The old, faded streamer showed up 
fairly well on this species due to its dark body.
