SPMayers 1977 Journal Prudhoe Bay, N.Slope, Alaska 28 July (cont'd) absolutely stupendous juvenile Calidris pusilla movement: Initially 1000's of these burgers, largely by the coast but also inland - this began w/180 C. pusilla juveniles by MANA in a seepage pond by the road, flourishing with a mix of Phalaropus fulicarius adults (~80), Calidris bairdi (6), C. melanotos (7), C. leucura, (adult + juveniles). After Shuford and I censused the area: C. melanotos 7 C. alpina 1 C. pusilla 180 ~ .75 ha C. bairdi 76 C. leucura 3 Ph. lobatus 80 Ph. fulicarius j 5 Calidris lay 10 Motacilla flava 1 But the real surge appeared coastally north of our central camp/impromptu, continuing as far as the Porcupine marshes north of west dock (as far as we went). Flocks of juvenile scapulifrons scattered everywhere, flocks ranging 50+ birds, foraging in Puccinella marsh, foraging on the gravel road top, foraging along lake margins in the coastal vicinity. We placed transects at West Dock within Naeling Island NW ~ 8 km. The pusilla were restricted to the very coastal strip, largely within 500 m. One extraordinary location was along the south bank of the Pot river in an area where salt water had killed an expanse of Carex lawrencei polygons. It was strewn with C. pusilla, many behaving aggressively, actively defending a 1-2 meters in length. Saw some classic calidridin aggressive patterns, including a crowch, wing out, etc. [see spp. accent]. Golden Plover adults are now very conspicuous also - occurring in both upland and lowland habitats but accepted toward upland. Phralis squatarola are also moving in, all adults, exclusively in low wet places. Transect description (3D) - begin near creek sock parking lot + goes west, starting on flat center polygon, out small arm + plunging into a marshy lake basin w/ Arctophila pond, Carex aquatilis, Hyperus tetraphylla, Ranunculus palmeri. Much Salix pulchra on Eip's contracting markedly with all other transects before today except the PAF series (which Skip Weller attributes to acidophilic tendency of Eip: and calcareous nature of most Prudhoe tundra due to aeolian deposits). (32) begin near end of Dan Lake basin + wade abruptly on rim after passing through a lot of barely polygonized marsh. Rimming Salix vahlii. It then goes through a patch of frost boil tundra with noticeably you-mire calcareous
