JP Muyes 1976 Journal GRID 2 Barrow, Alaska 8 June (Cont'd) booting, cloving, displaying almost continuously. See melanotos apparent. FAP arrived in pm. 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. One short-tailed weasel, plus areas of dense weasel tracks, at (30) GRID TOTALS 25 ha. 3 hr Arenaria intermus 4 (2 pros displaying) Calidris alba 1 (feeding) C. alpina 67 (pairs unpairing partly or wholly on grid) [illegible] C. brachyura 1 C. melanotos 8 4 C. pusilla 2 (one pair) Limnodromus scolopaceus 7 (one pair + 5 flankers) Stercorarius pomarinus Larus hyperboreus 2 Phalacrocorax fulicarius 0 9 Calcarius lapponicus 8 9 After censusing, I tracked a Stercorarius (6/9/76-3) for 50 minutes, with several notable lacunae in the data.
