November 29 - December 2 
and 
December 7“l4, 1965 
Introduction - Non Grid 
A total of 1748 birds of 26 species were recorded in 113 hours of 
diurnal observation covering $62 miles during the periods 29 November - 
2 December and 7“l4 December. 
All species groups except Terns showed a decrease in numbers over 
November. The largest drop appeared in the Shearwater-Petrels, primarily 
due to a reduction in Slenderbilled Shearwaters at the conclusion of the 
fall migration. Sooty Terns, the main component of the Tern group, did 
show a decrease but this was offset by increases in Fairy Terns and 
Common Noddies. 
Flocks totalled 57* More than half of these were of Slenderbilled 
Shearwaters between Oahu and the grid. The remainder was mostly mixed 
flocks south of the Leeward Hawaiian islands from French Frigate Shoals 
to Oahu; none were 'observed from the grid to Laysan.
