13 July Barrow, Alaska - The adults seemed to be out of each
other and no clutches were seen although birds seldom
came into close contact. The chicks froze at my approach
and were difficult to see. They would not move even
when disturbed with my foot. Nest 9 contained 3
eggs.
14 July Nests 10 and that near USC+55 with eggs. A group
of 5 found in the ponds W of line 2+3 and 2 seen
in Central Beach. Still hear a little parachuting as
the coming molt of individuals is less evident due to
feather growth. There are several pairs obviously
nesting on gasoline Ridge S of hills BTT, but we
were unable to find any nests.
15 July The bride on nest 3 sitting. Not many seen
during the day but a piece of egg shell was found
near line 5T on Pitelka's census plot in the evening.
16 July One of the nests found 10 July smashed by the silver
not checked. Saltated birds seen along Elson bayou
but not elsewhere. From the egg contents this nest
above was not a very old one, and Nest 3 eggs found. The
nest appeared to have been stepped upon.
17 July Adults in the area where found 13 July and two
young were seen. The chicks are much stronger now
and when approached they get up and run; they can
move! The adults seem as inclined to brood as earlier
and the chicks look larger but not much plumage change.
19 July Nest 3 hatched, 3 young ready to leave the nest and
1 adult in the area.
