GRID 3, BARROW, Alaska
9 June
10:30-1200; 14:30-1600 censused GRID 3 - 25 ha. SNOW COVER - 58% over
entire grid, with variance (100 50x50m units estimated visually) from 10-80%. Weather was
cold - ~34°, with a light NE wind and 100% overcast. The jaeger scene on the grid is difficult to
interpret. What appears to be happening over the entire area (along Gaswell Road) is that a flock of
jaegers appeared into an area have moved in, and they are slowly moving their focal point as the snow
clears in new areas. Glorious gulls and short-eared owls move with them, at least to a certain
extent. Thurs-3 June the concentration was on the small extension of Beach Ridge cutting across
as Well - about the first area cleared. Then 4-5 June they appeared on the Bunker area
(“even the” this mucked [illegible] at the same time as the previous spot). Now there is a small
group - ~6 using the central area of GRID 3. At first I took them for a very dense array of
lunular birds, as 4 of them are dispersed in tight pairs, but and they were calling and
arguing. But it was their spacing behavior bore no special relationship to fixed points
in space - in fact it was sporadic at best. Nonetheless, Adjacent to the grid - particularly
along Beach Ridge to the E., and Village Ridge to the S., lunular pairs are doing their flying.

in the data.
