Gull sp.) 
One unidentified small gull was collected within the grid on 7 
March. 
Sooty Tern ( Sterna fuscata ) 
This month showed a substantial increase in the numbers of this 
species. Of the 2,430 individuals identified, somewhat less than 
two percent were found within the grid, while 61 percent were near 
the Johnston-Sand Atoll. This represents, however, an increas e in 
abundance within the grid after a complete absence of the species for 
two months. One flying immature bird was collected just nothheast of 
the Johnston-Sand Atoll. This possible indicates the presence of birds 
« * 
that had bred to the south of our area, perhaps Christmas Island. 
Seven Specimens were collected. 
G rey-backed Tern ( Sterna lunata ) 
Eleven individuals were identified about 400 miles southwest of 
Oahu. Most of these birds were mixed in with feeding flocks of Sooty 
Terns.
