One orange-streamered bird was coliectecJ from a largo feeding, 
flock about 22 miles RTl^ of Johnst''’n Atoll. This bird was an adult. 
It was banded 21, April 1966 as a nesting t)ird. Observation of tuin 
flock of Uooty ferns was difficult as Ih'^ birds fir^w directly into 
the sun. 
One immature bird was collected 275 miles E.N.l^/. of Johnston Atxrll.

in the large feeding flocks 20 miles of Johnston Atoll. 
(irey-backed Tern 
( Sterna lunata ) 
One Grey-back was observed. More may have been in some of the flocks 
but because of strong winds and poor light they were not distinguishable 
from dooty Terns. 
Tairy Tern 
(Gy<^is alba) 
!*elative large numbers of Eairy ferns were observed from Oalni 
to Johnston Atoll a total of W' terns. Most of these birds were ir’o\H ng 
in a northwesterly direction and vie re feeding as they w/ent. I fe^A 
that this movement corresponds with a relative absence of hairy Tf.‘rrs 
on Mi iway Atoll. These birds may have been out fending around ‘^A iway 
and been caught by strong winds and blown south or soutiieast about 
the last week in December and are row tryingto return to their 
Islands. On the return trip to Oatiu only about one half as many birds 
were observed.
