R.B. Hamilton 1965 Lemmus trimucronatus June 16 Lemmings were abundant in the area N of Wolschlag slough. They could be seen everywhere scouring from the exposed grass to cover under the snow. In one area I estimated as being less than 0,1 2000 Twenty lemmings were seen. The Lemmings seemed to be rooting in the ground when they were not disturbed. Once a large lemming was observed chasing another one. One of the lemmings was uttering a twittering note. A lemming was observed flushing a Pectoral Sandpiper by running where the sandpiper was standing. No predator was observed taking a lemming during my walk. June 17 In the Britton area Lemmings are not overly conspicuous. There is not much snow present for them to scromper under. Many lemmings were seen, nevertheless. June 18 Along Beach Ridge Lemmings were very abundant. They were seen on the bare patches, grubbing for shizom.s. when they were disturbed they would go under the snow. On several occasions one lemming was seen chasing another lemming. June 19 In the Britton area Lemmings do not seem too abundant. However there is a large population of only 2-3 juncos present so the population is probably high. Jun. 20 Not many Lemmings were seen. June 21 The number of Lemmings visible in the area seem to have increased somewhat. Several times Lemmings were seen chasing each other.
