Storm Petrels. The extreme north end of the northern section (25 miles of 
observations) and the southern section surveyed were low-density areas. 
The density increased in the southern part of the north section and remained 
high through the central section. On both sides of the 33°^5’N parallel 
which separates the north and central section, fairly high numbers of Storm 
Petrels were found associated with Velella (Windsailers) concentrations. 
Red-billed Tropicbird Phaethon aethereus - 1 
This is the second and northernmost record for this species in the Grid 
area. The bird was observed investigating flotsam in the Velella concen¬ 
tration at the boundary between the north and central section. It had a 
moderately long tail. 
Red Phalarope Phalaropus fulicarius - 11 
Phalarope sp. ^ 
15 
While three-fourths of the phalaropes were recorded from the south sec¬ 
tion and none from the north section this should not necessarily be taken 
as a function of latitude. Rather, I feel, the apparent relative densities 
are due more to the distance from land. The southern section was surveyed 
at around 200 miles from land whereas the north and central sections were 
100 (or less) miles from land. I suspect all phalaropes seen were reds. 
Pomarine Jaeger Stercorarius pomarinus - 1 
An adult bird was recorded flying north in the central section. 
Sterna sp. 1 
The single bird seen heading north was in the same Velella concentra¬ 
tion as previously noted. The bird appeared gray below, and was ten¬ 
tatively identified as an Arctic. 
(No mammals were recorded from the Grid.)
