The single individual was sighted about UO miles E of Johnston 
Island on 23 August* On 1$ August a compact flock of 30+ birds 
tentatively identified as belonging to this species was observed at 
reasonably close range approximately 70 miles S-SS Johnston* None was 
seen last month* 
Pale-footed Shearwater A»0 B*0 Ol 
The single individual was observed about U5 miles SW of Kaula on 
25 August# The bird was apparently feeding with Wedge-tails in a large 
1 
mixed feeding flock# None was recorded last month* 
White-necked Petrel A*0 B*2 0166 
Practically all birds (99/0 were observed during the period 22-21* August 
north of the Grid area# Last month only a few individuals were noted north 
of the Grid, although large numbers (188) were recorded within the Grid# 
There apparently has been a pronounced movement to the north and west; the 
greatest concentrations were found to the east and north of the Line Islands 
in Hay and June# The numbers appear to drop quite abruptly near the m a i n 
islands where Wedge-tails are extremely abundant# This might indicate 
'9 
competition for food between the two species, but it is possible that the 
movement northward is still in progress# Numbers of the cervicalis race 
| were low this month in contrast to last month# However, only hO% of the 
t 
total observed this month were identified to race#
