H Verbeek 1966 Calidris pusillus (2) Found one more nest with 3 egg (#3) at 21:00. In contrast to the previous two, this one was on flat ground among small clumps of mosses. The nest itself had a few bits of greases in it, but was otherwise quite untidy. It is interesting that all three nests found so far in this area have three eggs - it, the first of which must have been laid on Monday (10 June). The 12th was the first real warm day and during the three days following much snow melted. The nests were built on those places which were exposed before the big melt off 16 June Found another nest with 3 egg at 15:00. (#4). Noticed one bird feeding on a dense mat of pure moss. He was brusquely engaged picking things off the surface of the moss. When I chased him off I noticed, after staring at the moss for a minute or so, tiny, 4mm. long larvae collected some. The bird feeding on this produced feeding observation 218, 249 17 June Nest 4 had four eggs. 19 June Saw two males chasing each other on the edge of their territory. The boundary was apparently formed by the gas line, because when bird A went into territory B, about 5 m. beyond the gasline, the B turned around to chase A. In this manner they flew back and forth, flying as well over as under the pipe. 20 June Found one new nest #5 with 4 egg on the Beach Ridge. The female flushed like a confused ball of vibrating feathers and squeaks and left this up for some 25 m.
