12 Nov. cont
usually small flocks of from 2 to 5 birds would fly over
the reef together. ~ This happened repeatedly during
the hours from 1030 to 1300 with the Red-feet, and is
probably correlated also with wind direction, which was
from the South today.
The Brown Boobies took a different pattern, flying
over the West or inside beach along the Scaevola,
flying alon the beach, over south point, and then
continuing along the inside of the reef until they dis-
appeared from sight near Sand Island. Do all the species
have their own route? This can b e checked. Is the
route correlated with the wind or rather stereotyped
and independent of wind direction? There is probably
a general pattern overlaying a wide degree of individual
variety - time will tell.
After dark 5 Wedge-tails (Imm.) flew into the side
of the building near our quarters - prob. attached to
the light. The young wedge-tails are all losing down,
several of todays study chicks had no quills alive, and
tonight increased activity of the young is noted. Most
will probably be gone very quickly now.
Copulations were seen in the Black Gooney for the
first time. Several pairs now have nests - shallow
scrapes in the sand lined with plucked, green Scaevola
leaves. Laysans continue to arrive, but no displaying
is yet evident.
13 Nov. The shorebird count occupied a good part of the
morning. I had the shore, and counted 31 Golden Plover,
78 Ruddy Turnstones, 10 Wandering Tattler, 7 Sanderlings,
1 Bristle-thighed Curlew, 43 Common Noddy Terns, 18
Laysans. and close to 150 Black-footed Albatross.
Also on the beach were 17 Seals, the tags of 8 of
them were read. One seal had a broken tag. No. 208
has new pelage, and is very clean and shiny looking in
a deep grey, rather than brown, that she has. Other
tags were 333, 214, 276, 342, 231, 202, and 249.
I banded a mist netted Ruddy Turnstone, finishing
another string of 2 bands - 642-00300. Two Sooty Storm
Petrels were found in the study area 2 where Bob found
them several days ago. One bird we had banded 9 days
ago - x612-005bxx 642-00292. The other was and unbanded
bird.
