Journal Brudhoe Bay, Alaska 20 July (Cont'd) a few broody Phyllocarvus plus a small group (3) evidently not broody. Essentially our trip was who birds - even Calcanius - for the first 2-5 hours as we trudged over upland tussock tundra, and past an occasional small pond or low polygon area. In a few places Golden Flowers or Black Bellies made their presence known. One flight of melanotis - ~20 birds moved E. We climbed a pinga - [illegible] flowering Dryas (past peak), Astragalus umbellifer, Papaver Macouni, a few flowering Oxymatry quinculent Oxypolis. Several Calcanius foraged around this pinga. As we sat on the pinga a herd of 4 q Rangifer plus ~20 q moved by; the q had one young with them and they kept going past us rapidly. The qst moved along and in fact seemed somewhat curious. Antlers on qst quite large but still velvety, foraging on Salix in the low center polygon centers. From the pinga to the SW we were able to see an extensive mosaic of ponds + lakes with thin isthmuses connecting them. Already before the pinga we had seen that array from Lake shore Humeau nothing, culde near the 1st lake line we hit just before the pinga that had been broody phalacrocorax. So we treked on down to the pond/lake/isthmus mosaic. It was a neat little shorebird center, with all the species listed above. Each margin of Archibelia had one or 2 phalacrocorax of either species. Scattered small groups of pectorals, breeding both broody and not broody, limnocorous. But curiously we found C. alpina and C. pusilla in only one place, the alpina on the lower side of a pinga and the alpina nearby (pinga 30 m from lake shore). Both were broody. Larus hyperboreus with one downy chick. Caria arctica probably upland. Anser allifrons w/grow. Walking back through the mosaic we passed through an area of low but regular numbers (i.e. 1 q melanotis every 100-300 m etc). Then suddenly we stumbled in to another center - 19 melanotis, 2 pairs of alpina, 15 chimaerops, 1 Puviali dominian, 2 juvenile pusilla, 1 Phalacrocorax. Habitat was not strikingly different from other small ponds in the mosaic, but the birds were markedly concentrated there. EVENING - talked w/ Wayne Hansen. His hostility seemed reduced this time. Learned that security likely to become more strict. Avoid Joe Morgan at Arco's bent strategy to make access inquiries at management level above turning on oilfield. Birds are inaudibly perceptible - a breeding Limosa fedoa at Franklin Bluffa. I want to see their photographs. High nest mortality there, an order of 70%, mostly due to July 3-4 storm.
