Calcarius lapponicus (3)
was located on the W. side of Honey Bucket. The nest was located
in the side of a wheel track. Pitelka and I found a third nest
4 eggs, between the road and the East side of South Salt Lagoon.
20 June
Found two more nests today #6, #7, each with 5 eggs,
on the Beach Bridge. The nests were about 40 m. apart. I
also marked an older nest #8 with 5 eggs. This female
was reluctant to leave. I had to touch her with my pencil
before she jumped out of the nest.
21 June
Noticed a group of three males feeding peacefully together.
25 June
The first young of the year hatched in nest #1. Of the 6 eggs
5 had hatched and the 6th had just come out of the shell.
The two shell halves were still - the nest. (22:00).
26 June
Found nest (#9) with 4 eggs in it on the Britton Area.
27 June
Found nest (#10) with 4 small young (all dry) and eyes closed S. of
Imikpuk.
The parties of 8 and 9 long spurs are becoming more frequent.
They seem to move about in small flocks. Saw one such flock
of 30-39 feeding together in the grass of a high polygon.
