Certhia murina 27 June. Meade River Coal Mine, 150°25'W, 70°29'N. 4 eggs near the large lake. Saw only 1-2 in the upland polygonal areas. One seen along the river banks. 28 June All nests on the plot O.K. A pair seems to be interested in the area by the dig out on the coal mine and 1-2 pairs between the mine and decrease plot along the river. The pair between on the plot in this region seems to have moved out. 29 June Several swans inland on the boulder, noted only at the outlet of intiogue creek at the 2nd lake and along the shelf on the lake to the south, where at least 100 pairs were present. One was feeding on a clump of weed and nesting in the marble lake bottom. 30 June The nests on the census plot seem to be O.K., but the birds were little in evidence in the A.M. There were two birds chasing insects on the Certhia murina - Certhia plots opposite the M lake by the census plot in the morning. In the afternoon I went back and quickly found two birds feeding. When I went to check them, they flew to a second spot, and I noticed that now 5 birds were together, plus a C. murina. They ran about actively pecking for insects. I got down and looked, and quickly found several mosquitoes, which appear to be here when the wind blows. When I went to look for the Tumblins, I thus flushed a group of 9 birds +2-3
