quadrant of the grid. 
Sooty Tern (U0$) 
This spedes showed approximately the same decrease from July as the 
Wedge-tailed Shearwater (16%), while also comprising a nearly identical 
percentage of the total birds (U8£) both months. Distribution was also 
nearly identical to the Wedgetails this month, with none being recorded on 
the first day and a steady daily increase from east to west thereafter up 
to the point of departure from the usual grid route. Of the total, 1*00 
were contained in 11 flocks. Nearly half of these (185) occurred in three 
flocks on the northwest leg August 20, in the closest area to Johnston 
Island covered in daylight. Other flocks were distributed randomly. 
Common Noddy Tern (1) 
This species occurs irregularly in the grid area, always in low 
numbers. The single individual was seen on 16 August in the eastern 
quadrant of the grid. 
Fairy Tern (11) 
Four sightings were of isolated birds. The remainder were in mixed 
flocks, usually in pairs. All but two were found in the vicinity of the 
northwest—southeast axis of the grid, 150-180 miles from Johnston Island. 
None were observed in the grid last month.
