this supplies more evidence that the season is late. The females
while Pitelka shot yesterday showed only early stages of brood-
pitch development and I believe only one out of 6 had laid egg.
On the W. shore of Elson hagoon I found a nest with one egg
in it. Of the three birds Pitelka shot there, two had oviphased
follicles, and One had laid an egg, the other had a large egg,
lacking the final calcareous shell in the oviduct.
11 June
Found a nest with 3 eggs in it W of Honey Bucket hagoon. The
nest I found on 9 June, partially lined had no eggs yet.
Along the N. shore of Ukpik though I flashed a female of her
nest of 4 eggs. The fluttered low than the grass for some 20 m.
12 June
Saw a male picking up bits of grass while he walked very
energetically and in a "frustrated" manner with his tail
spread and pressed down and his wings held partly open away
from his body. After walking about one to 1½ meters he flew up
about 10 meters high and uttered his flight song, causing his
pieces of straw to fall to the ground. After a while he repeated
this performance, again taking the straws with him into
the air and dropping them. The male was alone when he
displayed as noted above.
13 June
The nest which appeared completed on June 9, contained
3 eggs.
14 June
Found three more nests today; all in the drum area. One
with 6, 1 ad 4 eggs. The one with 6 eggs is nest #5
16 June
Found one nest with 4 eggs. The nest was in a collapsed lemming
tunnel and thus had a roof over it. A second nest with 4 eggs
