Sooty Tern 
1 
August 12 — Pacific Ocean, Grid Area off Johnston Island 
1253. One Sooty Sighted flying at about 75 feed. It kept trying to fly into 
the wind, but was constantly pushed back after about 30 seconds. It tried about 
4 times then gave up and flew headed SW before the wind. The wind was blowing 
at 15 knots at this time. 
1333. One Sooty being blown SW before the wind which is still at 15 knots. This 
bird tried about 3-4 times to turn back into the wind, but like the last bird could only 
stay for about 30 seconds each time. 
1429. Flock of 10 Sooty Terns drifting generally to NW, wind has died down. 
1* 25 f up. 
1440. Flock of 20 Sooties l f 5 T up headed E into wind. 
1443. 1 S headed N joined flock moving to E. 
1451. Flock of 14 W headed W 5-10* up. The wind is now at 10 knots. 
Evidently these birds prefer the E direction (which is generally toward 
Johnston Island) but can only make it when the wind is belcw 15 knots. 10 knots 
appears to slow them down and keep them low but they can still fly into it.
