Holmes, R 1939 Plectrophenax nivalis 4. 15 june Barrow, Alaska Several pairs are building nests around the base. One is located under the roof of the Narta shop. Another is on a stack of tires behind a shed about 30 yards behind ABL. The nest was composed of straw, sticks, grass and mud. No eggs had been laid by this morning. The mud appeared to be stuck on the pieces of grass and it was probably not put there intentionally. At 1330, there were still no eggs in the nest. Also, none at 2200. 17 june Barrow, Alaska The nest in the stack of tires contained 2 eggs at 1100. The pair were not present nor near the nest at this time. 18 june Barrow, Alaska The above nest contained 3 eggs at 1000. 19 june Barrow, Alaska The nest contained 4 eggs at 1200. These birds are still seen frequently in pairs and nesting may not be completely underway yet. However, most pairs probably have begun their nesting. The males can be heard singing throughout the tundra at all times during the day.
