Jr Myers 1976 Journal GRID 4, Barrow, Alaska 25 August (cnt’d) Dunliners are actually quite abundant now, and all juveniles. As reflected in the transect and grid data, they occur in hummocky pond areas, along the water’s edge, in Salix emergens, Carex aquatilis (stand 21), and out in the centers of ponds. Foraging style is classic dunlin sewing-machine motion. Nunavak Bay, 10 km SW of Barrow, Alaska 26 August 0700 three-wheelers) down to Nunavak Bay. Weather clear but windy, 39°, fogging up by 1100. Drove 2 km beyond the mouth of Nunavak, spent 1 hr walking about the ponds on the tundra, and then returned, arriving at NARL by 1100. Route down is mostly gravel road, through Barrow, and then along the Chukchi shore after reaching Nunavak. Passes through low wet tundra just beyond Barrow but then enters high bluffs by the shore. South of Nunavak it is to high rolling tundra, rather dry, cut by ravines and small drainages. Steeper slopes covered with Salix viminalis, while the intervening areas are covered with a Carex association similar to Carex-Poa or perhaps the Carex with fruticose lichens (#5). Polygonum present but not excessive. Few birds on the tundra — mostly Limnodromus scolopaceus juveniles wheeling overhead, and several flights of Calidris melanotos. # Up to 50 C. alpina, almost all (but 4) juveniles, most on the shore. Very few phalaropes on the shore, but a large flock (120°) Sterna paradisaea at the mouth of Nunavak, plunge- living and feeding. Few birds off shore, mostly foraging terns, heavily clumped. One pod of whales, probably grey. Barrow Spit 27 August 0930-1200 censused a series of transects along Barrow spit for Peter Connors. 39° moderate ENE, high fog. Remarkably, I counted 37 red phalaropes along 5 transects, and estimated there to be 100-200 on the entire spit. Thus within the last few days, the population of red phalaropes has dropped from 1800-2000 to the low level recorded today. Dunlin juveniles were the most abundant shorebird, although not very, with somewhere between 100-200 present. Suddy Turnstone and Sandling roughly the same abundance as dunlin. Several hundred (300?) arctic terns. 1 Rissa. No Xema. For the last
