PELAGIC SURVEY REPORT 
This report covers 111 hours, and 916 miles of diurnal observation 
between Oahu and the Smithsonian Grid I, during the periods of December 1-7, 
and December 13-17. A total of 1,223 birds of 20 species were recorded 
and U specimens of 2 species were collected. A special track was followed 
around Johnston Island to determine bird population to the northeast of 
the atoll. Nocturnal observations were held in this area (see table £) 
and bird density was very low. The Smithsonian observation party included 
Brian Harrington (BIC), Walter Bulmer, Janies Lewis, and Frank Smith.. 
The main concentration of birds was found from Oahu to about 300 
miles 8.W. of the island. In this area large feeding flocks of shearwater- 
petrels and terns were observed on the trip down but not on the return. 
This phenomenon agrees with last years finding and it is presumed that terns 
and shearwater-petrels move through this area possibly heading southeast. 
In general bird populations were down from last month and were similar 
to those of last December. 
ANNOTATED SPECIES LIST 
BIRD 
Black-footed Albatross 
(Diomedea nigripes ) 
Three birds followed the ship as it left Oahu. No others were 
observed. 
Wedge-tailed Shearwater 
( Puffinus pacificus ) 
Wedge-tails were found in feeding flocks from December 1 to 5. After 
this time, most sightings were immature birds that showed up around sunrise. 
The flocks southwest of Oahu were probably immatures leaving their Hawaiian 
breeding grounds and moving casually southeasterly.
