Grid 2, NAKL, Barrow, Alaska
16 June On the Barrow tower at last! I've spent the last two days inside working
on Atkaskool Tryngity notes.. This am @ 0830 went to Grid 2 in
order to work on Celidris melanotos. Remain on G-2 out/ 1430, then
walked to Gy, then back to NAKL @ 1630. Weather spectacular.
32°@ 0500 (up @ 0300 to finish notes). Light NW wind. 8 clouds.
The melanotos scene, however, was a big disappointment, with few
PP and fewer PP on the grid and elsewhere. See melanotos sp acct.
17 June Up at 0930 and on Grid2 by 0445. See melanotos sp account- Weather
belong - almost no wind and until 1100 no clouds. Temp 34°-38°F. I censured the
grid through the day from 0445-1330, then returned to camp. The morning
began with a bit of drama as I found 3 different jaegers eating 3 different
shorebirds: 1 S. pomarinus eating either a C. melanotos or a C. bairdii (it flew
off with its prey) and 2 S. parasiticus, one with a C. pusilla and the other a
C. melanotos. Yesterday we watched a S. parasiticus eat a C. calpinna. Today
McLaffing saw an S. parasiticus catch and eat a P. fulicarius. It's not a safe place to
be a shorebird on the tundra. Two nests found yesterday on Grid2 were torn
around by jaegers in the intervening time: that of an Arctia acuta and a
Calcarius. It looks as if the jaegers are turning to birds. I should note that the
lemmings picture is rather spotty: a few places have dreary, complete grazing, spread over
0.25 ha or more. But most coting involve a few square m, at most a radius of
5m. Winter nests are spotted throughout the tundra. Thus there were lemmings
around but they have crashed from whatever density they attained. The jaeger scene
reflects that: at least one pair of S. parasiticus is defending near Grids 1 & 2, but
there is also a S. pomarinus defending also. Further, there seems to be a single
light-phase S. pomarinus defending a small area on Grid 7. Finally, Asofleummus
continues to abound. One or two hunted near Grid2 all day long.
