JPM Myers 1977 Journal Prudhoe Bay, North Slope, Alaska 20 July (cont'd) But a heavy fraction also lost to avian predators. Low density: over 100 or so ha they found 8 meter mats, [illegible], C. calceolus, C. fulicarius, a few more of other spp. I am somewhat skeptical of the accuracy of these densities. With reference to Prudhoe Bay, Fauson tells me that melanotars do NOT vary in density to any great extent, at least over the last few years (1971 on). West Dock → Pt. Storkeuson Dew line 21 July 0900→1700 in field between Pt. Storkeuson and West Dock, scouting the habitat w/Dave Shoford. Weather began ominously in a sense, quite pleasantly + thickly threatening for mosquitos. But acold breeze and midday fog kept them down, and proved only slightly chilling for us. We traversed a diverse array of habitats, ranging from coastal salt marsh to lowland Cares pond/lakeside heavy on Arctophyllum and Cryphonium angustifolium to dry creekside ridge and upland Tundra. As I discovered in late June, [illegible] Pat Webber's description of this area as a Barrow analog is appropriate. But blooming Dryas kept me aware of the fact that we weren't at Barrow. Here the Dryas and Papaver are much more widespread in wetness regimes than at Barrow, growing much between moist tundra, as well as higher ridges. As yesterday, the general theme of the outing was absence, but not as stark as yesterday. Thin was probably a result of our never spending extended, uninterrupted periods in pure upland tundra. But not entirely, because even three birds could be found (P. dominica, C. alpina, C. lapponicus). We went through one very extensive lowland mosaic of ponds, lakes, + Carex marsh, ~1500 m NW of the west dock parking lot. This area had relatively high densities of expected species - C. melandrus, C. alpina, C. pumila, Ph. fulicarius, Cavia s+a, Somateria spectabilis. Very low polygonization here, except a high % surface water even across thin salt in a dry seam. To my surprise there also were Pluvialis squatarola - a flock of 5, and P. dominica - several small groups that represents [illegible] flock of P. squatarola I've ever seen on the north slope. Also explored a large salt marsh extending inland several hundred meters, bordered on the upland side by a wide swath of what it interrupts to be salt-burned normal tundra (a blackish mass of dead moss Carex?). Saw perhaps 2 Calegivis in all of that much - no shorebirds. From these there passed into a flat polygon region similar to Barrow draining moist meadow. Few pajaritos graced the land. Only within about 700 m of Pt. Storkeuson Dew line, just after crossing a Puccinella sloop,
