movement of alpina continuing today. Also display activity + chowing, which appears to have
concentrated in vicinity of airstrip. Nevertheless many of the birds that appear [illegible] remain
only momentarily. Flight direction strongly to E, some N. The net movement is clearest
in alpina of all the shorebirds, and approaches the consisting of Stictracris pomarinus.

Carex bigelowii partially buried under wind blown sand downwind from a large riverbank blowout.
