NARL, Barrow, Alaska
22 June (cont'd)
Have been maneuvering in a bitter fight with operations management. They have flown only once since (3 June - to take me back to Alaska). At first it was a blatant refusal, + for the last several days the chief pilot Larry Walls has been 'sick'. A classic work slowdown. All the science projects (all being not very many this year) are suffering. So I chartered a Cape Smythe flight for the afternoon of the 23rd.
Back to the grid. Compared to what I have been seeing on Grid 4 these last few days this area is slow, at least for nulcaeter and folicaeus, barodit + Pluvialis, however all quite dense. I estimate ~0.2 territories/ha for Bairdii, and ~0.15 for Pluvialis. These data are all in our grid books. Both figures are the highest I've ever recorded, although little cleaner highs. See tomorrow's summary.
23 June This spring at NARL - the shorebird/passerine scene.
Pluvialis dominica - see note in Journal of 14 June and 22 June. A high year for Pluvialis. They are an all habitat, uplands and lowlands. While we have not banded birds I will venture that there are quite a few floaters around also, including $. I suggest this because of the # of both sexes seen flying about, being chased out of territories, etc. Pluvialis are nesting abundantly even on Grid 4 - although the transect data may show some preference for uplands [the strong case for all previous years.
Charadrius semipalmatus - A o' has been displaying regularly over the lab. Unfortunately, a construction company did in Britton Ponds, our usual Ch.s. breeding site. They put up a camp that deprives us of a guaranteed sighting every day. But they are around.
Arrecaria cyanea - nothing unusual happening this year. There are the usual 2-3 pairs on Grids 1 and 2.
Calidris melanotos - contradictory data, spectacularly so. In the 1st week
