SMITHSONIAN GRID ONLY 
This report is based on the collections and observations made within 
the Smithsonian Grid during late August, 196f>« A total of six days (16-21 
91 I 
August) were completed covering a total of 658 linear miles and 75«5 hours 
of diurnal observations* 
The Smithsonian team consisted of Richard Crossin (Biologist in charge)* 
Ken Amerman, Dayle Husted, Brian Harrington, and Jeff Tordoff# Excellent 
cooperation was received from the officers and crew of the U.S.N.S. SHEARWATER# 
Normal grid procedure was interrupted on the morning of 21 August 
(6th day in the grid) when it became necessary to take one of the crew 
members of the SHEARWATER to Johnston Island# The westernmost leg of the 
grid remained to be run (see map)# Diurnal observations were made while 
in the grid area during the remainder of the 21st while enroute to Johnston 
* 
and are included in the total observations. 
The total number of birds seen (8U9) was considerably lower than last 
month# Sooty Terns made up approximately $0% of the total# Petrels, espec¬ 
ially the small Pterodroma , were considerably fewer than last month. 
Relatively few flocks were encountered (13) and these were generally small# 
Sooty Terns were especially wary and would split away from a feeding flock 
% 
and practically vanish whenever the ship approached* Only two were collected 
during the grid cruise.
