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°45'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 concentration at the boundary between the north and central section. It had a moderately long tail. Red Phalarope Phalarope sp. Phalaropus fulicarius - 11 4 15 While three-fourths of the phalaropes were recorded from the south section 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 concentration as previously noted. The bird appeared gray below, and was tentatively identified as an Arctic. (No mammals were recorded from the Grid.) TABLE 1.
