SPECIES ACCOUNTS 
WEDGE-TAILED SHEARWATER (137 + 9 nocturnal) 
Numbers were somewhat higher than last month. This species can be expected 
to increase in the grid area as the current breeding cycle of southern pop¬ 
ulations moves to a close. 100 7. of the birds recorded to color phase were 
dark. 
SOOTY/SLENDER-BILLED SHEARWATER (20 + 2 nocturnal) 
Similar to last month* practically all sightings were of single birds moving 
in N or NW directions. One Sooty Shearwater was collected at night. Nor¬ 
mally, neither of these species venture near the ship at any time. If the 
spring and fall migrations of the past year are at all typical, a heavy fall 
migration southward and a sparse northward spring migration can be postulated 
through the southern grid area. 
AUDUBON*S SHEARWATER (20 nocturnal) 
Curiously, this species was not encountered during diurnal observations but 
was present every night. Three specimens were collected. The recording and 
collecting of such forms only at night demonstrates the importance of noctur¬ 
nal drift stations whereby collecting can be performed throughout the entire 
observation period. 
KSRKAPEC PETREL (1) 
This species has been recorded irregularly in low numbers since last fall. 
No specimens have yet been collected within the grid. 
M)TTLED PETREL (1) 
The sparse northward spring migration of this species appears to be over. A
