section alone being void. Over 70 percent of the Red Phalaropes were
recorded in a five-mile stretch in section "T". These flocks were not
noted in association with slicks as had been the regular phenomenon in
previous observations in this area. A handful of small flocks of Reds
and the single Northern were seen on slicks in sections "Y" and "W".
Sightings of individuals in the western areas were partly of individuals
heading south. The increase of birds at this time of year may possibly
indicate that the south-bound fall migration is much more delayed than
previously thought.
Bonaparte's Gull
Larus philadelphia
Both adults and immatures are presently moving south at some distance
from the coast. The species was common in the nongrid area to the north
and appeared in low numbers on the easternmost edge of the Grid. Two
immatures were collected and it would appear that immatures venture
farther offshore than do adults.

# observed in each section
The high numbers recorded in section "T" are somewhat artificial.
Thirty-three birds followed the ship onto the Grid from the coastal non-
gird leg to the north. Twenty-five birds appeared on the 8th just as a
westbound freighter passed seven miles astern of the survey vessel. The
ship following tendency which evidently is exaggerated at this time of year
no doubt plays an important part in distributing Herring Gulls out into
the pelagic zone. Three of the 58 birds in section "T" were adults
(5 percent), the remaining immatures were about three-fourths 1st winter
birds and one-fourth 2nd winter birds. Of the birds in the rest of the
Grid four of 13 (30 percent) were adults. No birds were recorded in the
southern third.
Tern sp.
Arctic (?) Tern
A group of four unidentified sterna was observed heading east in
section "W". A single bird heading south at sunset in section "X" appeared
to be gray below and probably was indeed an Arctic. The date 6 November
is very late for this typically early migrating species.
Cassin's (?) Auklet
Two small (all dark?) alcids were pursued from the skiff in section
"Z".
