Sign of such movements evaporated - well not quite all, but the decrease was remarkable.
Nonetheless I still saw small groups of moulators juveniles moving east, and juvenile red
phalaropes moving toward the coast.

Dunlins are very dense, but quite patchily distributed. Most were on transect 8. If today's
broad habitat use continues the dunlins will all be in low wet areas by the time
the next sample is taken - they are appearing in what used to be pure
pebbled habitat along transect 10, 8, 7, 6 etc.

Not only are there a plihood of alpina, but they are distributed almost exactly the
opposite of their distribution 10 days ago: very few today were in the Carex-Poa
mesic polygons, instead being in the low wet areas in the upper reaches of the
