July 12 Amchitka Island, Alaska
not see forward. His side vision was also restricted
by the pontoons which are placed to either side of the
copter. He did improve his vision by opening
the side door (right side) which was always the
landward side since our flight was primarily over
water just off shore & slightly above the elevation of
cliffs & sea stacks.
Our observing procedure changed partway along
until we reached
the route. From take off, the mtns, we flew
at a rather high speed. Although I saw 6 nests
(5 unplotted, 1 in Makarius Bay) I could not follow
the unfamiliar topography on both map & ground
fast enough to plot the nests & also record their
contents. Consequently I only recorded contents of
nests plus number of adults seen along the route.
One additional factor effected my efficiency. I was
using the small map segments 3M copied from
those of Leroy Bowl & these do not provide sufficient
perspective to keep oriented without constant turning
back & forth from one map to the next. Bob
had the larger maps below where he had more
room, but seeing as he had a poorer view, he
couldn't use them. He had seen only 2 nests
while I had seen 6 from my better vantage
point. On the other hand his count of adults
was similar to mine. We landed before reaching
the mtns proper & discussed possible changes in
