R.B. Hamilton 1965 Journal June 17 Barrow Alaska afternoon we went to the same area and again made observations on shore-bird feeding. The birds were displaying more in the afternoon than in the morning. Dunlin were observed giving airial displays. A White-rumped Sandpiper was seen giving a ground display. A nest of a Pomarine Jaeger was found which contained one egg. Sanderling were still feeding on the area in large numbers. By 1900 the temperature had dropped to 28°F. Much of the snow has melted in some parts of the Britton area. Even the troughs of the raised polygons are melted in some areas. June 18 The day is overcast. The temperature was about 31°F in the morning and 36°F in the afternoon. The wind is from the NE but at less velocity than previous days. In the morning I took about a 1 hr. walk in the Barrel area S of ARL. Sandpipers were giving flight displays repeatedly. Two nests cups were found and were probably being used for ground display by shorebirds. A Knot was seen flying over, headed N. In the afternoon I took a 3 hr. walk along Brook Ridge and back to the lab. The bird population on the ridge seems small. White-rumped Sandpipers were seen displaying there, however. Two jaegers were seen copulating. Lemmings were abundant and a Red Fox was seen on the way back.
