J P Myers 1976 Journal 26 FRANSECTS 6-10, Barrow, Alaska 6 July 0900 started out along the transect line, and was immediately interrupted by the quirk. #6 was dead, with very few birds along it, or so it seemed. No displaying activity until I reached the beginning of #7, after which there were sporadic P. melanotus hosts for the remainder of the morning. Weather absurd - almost windless, 10% clouds increasing to 50%. 400+. It was short sleeve weather at Barrow. While #6 was quaking, the others, particularly 8 and 10, were hopping. P. fullicarius present in strength. Totals are below, including those from transects 1-5, which Strawberry sampled yesterday and today TRANSECT SUMMARY 266 minutes per hectare 1-5 # density 6-10 205 minutes # density Polysticta skelkeri 1 .02 Pluvialis dominica 5 .1 Pluvialis dominica 0 0 Calpina 14 .28 C. algina 20 .4 C. bairdii 1 .02 C. mawvi 2 .04 C. melanotus 22 .44 C. melanotus 4 44 .88 C. melanotus 18 .36 C. pusilla 3 .06 Ph. fullicarius 15 .30 Areuaria i 1 .02 Areuaria 21 .01 Ph. fullicarius 16 .32 Stercorarius 2 .04 Ph. fullicarius 2 45 .90 Calcarius 22 .44 Calcarius 16 .32 Plectrophenax 3 .06 Nyctea 1 .02 Plectrophenax 1 .02 Drying of the tundra continues unabated - even stretch of the vent marsh along the upper end of transect 9 is dry in places. Potentilla is blooming in a few locations along the high polygons running through which #9 passes as it transfers from mucky polygonized areas to the marsh. I also found a small area by the end of #10 where Saxifraga oppositifolia subsp. Smalliana is in bloom, as well as Rumex just beginning - 7 July During the morning I cursed grid 3 - 0900-1200. Light NE wind, 34°, 95% clouds (a high fog). Again, the aspect of the GRID is markedly different from during the mutton period - I was attacked by 3rd phalarope as well as Scolopax, P. semipalmus, and P. melanotus as they carried chicks. Phalaropus displayed very infrequently, particularly in the upper section of the GRID, and the fact it may be that this is concurrent in his ways. Actually more than one P. migrans as I saw one border flight and a supplantation.
