The overall linear density of Sooty Terns increased two fold (from 
.95 birds/mile to 2.02) over the Sept.-Oct. survey. This coincides with 
the initiation of breeding on a number of the islands in the Phoenix group. 
On December 7 over 3,000 birds were recorded in large flocks north 
of ^nderbury. These flocks were of a peculiar nature in that the birds 
were in most cases circling at very exaggerated heights; up to 800-9000 
feet in some cases. The flocks had the appearance of a swirl over an 
island before initial egglaying. The same type of flocking behavior has 
been seen in the vicinity of McKean Island. 
An immature Sooty Tern, banded as a local on Sand/Johgston in 
July, 1966 (no. 9U3-23575) was collected November 13 at 11 57' N., 
175 U9 1 W., some 900 miles southwest of Johnston Atoll.
