pressure system in and to the west of the OPAREA dominated the weather
for the first three days giving moderate to light northerly winds and
cloudless skies. A weak low on 3 November brought in thick low clouds
and occasional fog banks but little wind, and the seas became flat to
glassy. Seas and winds remained very light as a high pressure cell
moved in from the south and dominated the OPAREA from the 4th to the
7th producing light southerly winds and partly cloudy to clear skies.
A brief cold front passed through the area on the 8th but was not
severe and conditions remained excellent. Slick areas were noted
almost every day particularly in the south central areas, where logs
and floating debris were also noted. The slick areas previously noted
on the east end of the northernmost leg were not in evidence, although
the typically associated Red Phalarope flocks were seen.
Eastern Grid Survey #16
Over 846 miles and 86.8 hours of diurnal observations 843 birds
of 28 species were recorded. Ten birds of at least 4 species were re-
corded over 20 miles of nocturnal watch. Forty-eight birds of 8 species
and 1 turtle were collected. Eight sera samples were taken (see Summary
TABLES).

The influx of the expected wintering birds has not progressed rapidly
since the previous survey. Black-legged Kittiwakes have yet to appear
and alcids were represented by only one sighting. Fulmars have increased
only slowly. Herring Gulls appear to be increasing gradually in the north
and northeast. Red-tailed Tropicbirds from (probably) the Hawaiian post-
breeding dispersion were present in moderate numbers. Surprisingly high
numbers of three major Grid species; Red Phalarope, Leach's Storm Petrel,
and Sooty Shearwaters all point to a secondary general migration peak in
progress during the survey. Accidental landbirds are still significantly
present in the northeast half of the Grid area. Oceanographic features
