Calcaeus hypoxicus -7 16 June Meade River Coal Mine, 15°025'W, 70°24'N, Alaska Very little in evidence during the afternoon. Found a nest with 5 eggs on the SW side of a burrow under a willow or a polygon trough margin. The next on the census plot had 6 eggs, and this & here was the only one I saw the entire census period, except the 2 between Phil's transect and the 1/4 stake, as last time, and couldn't find 1/2 the 5s that were here before. 17 June Found a 5 egg nest on a high polygon ridge under a willow to of the village. L.H.L. activity. 18 June Found two 5 egg nests on the village flats. Both on polygon troughs under Eriophorum tufts, one under willow, one not. Both nests used feather weed. Several other 5s seen here. 19 June The 2 still incubating, and gives a distraction display when I approach. One other I seen on the plot and only a few males. Essentially no song any longer. Yesterday saw group of 35's in the village fleets and today saw 28's, prob. both non- breeding, near the census plot, together. I now suspect few birds actually nesting on the plot, but why? 20 June A small group of birds by the village bent the large assemblage of 3s are gone. Found a 5 and a 4 egg nest near the far end of Pitelka's Trough at Lake Ikkamaknak, with wide Eriophorum tufts on polygon troughs (near the top). Little song.
