Longhurst 1939 Citellus grammurus Aug. 12 Baker Cr., 6600 ft., White Pine Co., Nevada young. 5 were shot with a .22 rifle as they were too wild to approach with a shotgun. 2 of 3? Two of the ? were adult and had by the appearance of their mammary glands only recently weaned their young. When the old ones sighted us they would give a series of shrill squeaks spaced at regular intervals 10-15 sec. apart. Their squeeks those of the Calif. ground squirrel, but were not quite so loud and a little higher pitched. One old one was noted to travel about 40 yds. across the rocks and climb a Pinus monophylla and descend with a fresh out cone which it carried back among the rocks. The squirrels were most active in the early morning about an hr. after sunup. As they day grew warmer they retired to their holes and by about 6:00 A.M. only a few adults were seen moving about from time to time.
