JPMyeus 1978 Journal NARL, Barrow, North Slope Borough, Atkasook, Alaska 8 June 0700-1215 and 1500-1730 censusd grid 2. Another exceedingly warm day with the Temperature well above freezing throughout, after storky with a morning frost. Sky clear + air almost unstill. Snow cover on grid 2 down to under 20% as an average, although a few units still have 40% or so. Bird activity is intense, particularly among Caloceris, and Calidris alpina, and Calidris minutula as well as Phalaropus fulicarius. In all of them, birds, are very active. Floaters are conspicuous, and introduce difficulty into the censusing procedure. Among the territorial species, particularly floaters are tolerated to a certain degree even if the midday display activity. Thus pairs of quiet dunlin may or may not be localized breeders as yet. The laps are uphill in the throes of nest building. This spring has been another unusual season (-alas but what is usual) with the almost daily fluctuations between hot + cold temperatures. First a warm period in mid-May, then a cold one in late May. A few warm days in the last day or so of May followed by plummeting temps for a 3 day period. And now this lovely weather which has persisted now for 5 days + melted most of the snow. Atkasook on the Meade River, North Slope Borough, Alaska 9 June 1000 (weather) Atkasook and NARL Census 780. Flight revealed that snow melt is largely complete at Atkasook, but progressively less so toward the coast. At Barrow the overall average is ~20-30%. At Atkasook, after some troubles with the crew because of a broken durn generator + other deheating issues, Ben Vogel + I went out to begin placing our recent sticky board transects. Placed 12 boards along Transect A, which runs up bird transect #2. See 1978 Inventory/Transect Observation for a description of the habitats sampled. By the way, I should mention that the river here broken again a marine performance, according to everyone here. It flooded so that our breeding bird plot was under 7' of water as river water coursed down an overflow channel running into Butterfly Creek. There are marine icebergs everywhere up on shore. Birdwise the place is calmer than I expected. Low densities of melanderi, relatively low numbers of
