JP Myers 1976 Journal Grids 2+3, NARL, Barrow Alaska 8 August (cant) Again today I am impressed by the soldier sinkh in detail foraging near. On grid 3 they were foraging over the entire area, as indicated by their record position on the grid. One group, in the upper units, was associating with Phuialis as before. They were in the upland areas. Others were along the 'ridge' slope in the southern region, an area which has been benefit of birds for some time (Larus melanotus). Finally they were in the mixed polygon-pool region, foraging both on the polygons and in the pool edges. I was able to get micro points on them, Larus melanotus + Larus fulicarius. By mid-afternoon, during the census of grid 2, the wind had picked up considerably + the sky cleared somewhat. Of some relevance to shorebirds was the presence of 2 adult and 2 Nycticorax chicks (see boxes on data sheet). They were using the high polygon area where a flock of Phuialis + alpina [illegible] had been during the previous two censuses. This group was not there today. To what extent are the Nycticorax working against shorebirds - now I have 4 cases of places where Nycticorax apparently discouraged shorebird presence: transect 1 at an area around nest during first half of season; Grid 3 when jaegers were killed + Nycticorax moved in; transect 2 last census when Nycticorax had expanded range + chicks apparently moved, as I note this. Although this is almost impossible to substantiate without a fairly vigorous program, the arguments make sense. They also wrecked a certain havoc with my seasonal's in s-bird densities. Flock of Branta canadensis flying over today; a possible Falco rusticolus - an obvious, large + swift falcon in poor light over the road. Barrow Spit 9 August During the evening I took a Hevie whaler ~ 3 km out the spit from NARL, going as far as Whalebone Cove. Very cold - temp ~30° - snow + strong w wind. The wind has piled ice up along the Chuckchi shore. See trip list for birds. 10 August Transects (3,5) The snow which was falling intermittently last night remained, so that at 7 this a.m. there was snow over the tundra - not more than .25 cm, but a fairly continuous layer lay at 7 = 28°F; by 1400 it had risen to 32°F. Snow cover off by 1230. Strong
