JPMayers 1976 Journal 46 TRANSECTS 6-10, Barrow 9 August (cmt'l) Sign of such movements evaporated - well not quite all, but the decrease was remarkable. Nonetheless I still saw small groups of moulators juveniles moving east, and juvenile red phalaropes moving toward the coast. TRANSECT SUMMARY 1-5 50ha 6-10 210 minutes 50ha C. alpina C. alpina a 37 .74 j 5 .10 C. melanotus ♂ 2 .04 j 6 .12 Micropalama himantopus j 2 .04 Ph. fulicarius ♂ 1 .02 ♀ 19 .38 Stercorarius 5 .10 Calcarius l. 48 .96 Pluvialis dominica C. alpina a 58 1.16 j 7 .14 C. bairdii a 1 .02 j 0 0 C. melanotus ♂ 0 0 j 16 .32 Ph. fulicarius ♂ 1 .02 ♀ 0 0 j 17 .34 Stercorarius pomorius 5 .10 Calcarius lapponicus 42 .84 Dunlins are very dense, but quite patchily distributed. Most were on transect 8. If today's broad habitat use continues the dunlins will all be in low wet areas by the time the next sample is taken - they are appearing in what used to be pure pebbled habitat along transect 10, 8, 7, 6 etc. GRID 2- 10 August 0850-1115 censused grid 2. temp ~33° 100% clouds, light W wind. C. alpina a 51 j 2 C. bairdii j 1 C. indudator ♂ 1 ♀ 1 j 2 Ph. fulicarius ♂ 8 ♀ 0 j 14 Stercorarius pom a 9 j 2 Calcarius 19 Not only are there a plihood of alpina, but they are distributed almost exactly the opposite of their distribution 10 days ago: very few today were in the Carex-Poa mesic polygons, instead being in the low wet areas in the upper reaches of the
