J.P. Myers 1977 Journal Prudhoe Bay, N. Slope, Alaska 19 July Bridge toward Drill site #9. Large herd of caribou (mostly 80-50+ animals) adjacent to road. The Sag River basin where we crossed was devoid of birds + uninviting, a mass of gravel worked over by man + river. Also largely barren with the sand dunes between docks #1 and the Sag River Delta. Beautiful flowers (yet to be identified) but who birds. We passed over a large - 100m stretch of wet Carex aquatilis, Eriophorum russeolum, E. angustifolium low center polygon with many few birds. Only by the margin of a large lake where there any foraging shorebirds - 5 melanotos ?, ~10 Arenaria, several (5-10) xema), a broody Phalaropus lobatus ? , a Ph. foliarius ?. In the dunes we saw almost no birds. Did spook up 8 Pluvialis dominica but they took flight (if they indeed were on the ground) before we saw them. A flock of melanotos passed over calling mixed flock of Somateria, mostly speckled but probably molligani and 1 possible fischii. Out in the ocean flew some rafts of Changuia, a few Aythya (87 manitu plus one possible 9 affinis). Also birds looking like possibly Albatita Melanitta. But poor visual visibility of most of the ducks prevented positive ID. Spernophilus cat composite flowers. 20 July walked ~3 mi SW from S end of Big Lake, near Trans Hand 5, after leaving car at 0800, returning 1400. Much of route was incredibly devoid of bird life, but several pockets of activity were apparent. Weather 40-45°F, 100% clear w/ a low fog hanging off to the North. Light wind from NE growing through morning but never above 15mph. Temperature + wind remained low enough to keep even the horrendous mosquitoes down; although occasionally they rose to the occasion of our visit; particularly before 1100. Habitat: largely upland tundra mixed w/ frost boil habitat. (Climbed 2 pingos, also wandered about in midst of a nice lake system with...a mosaic of water bodies ranging from 50 to 200 m diameter (or long axis). It was in this complex of water + low tundra that we saw almost all the birds seen during the morning: geese (A.a.), tider, and all shorebirds: P. Squat, P. Petronius, C. alpina - some 60 chicks, C. pusilla (1 pair mobbing by lake shore), C. melanotos - 5 or so broody ?q, less than 30 in several flocks of evenly mixed (?8-?)q, C. hirundinops - (mobbed by Laddut), Limnodromus 5 - 2 small flocks of 10 or so, Ph. lobatus 45
