Lee Arnold 1937 Ammospermophilus leucurus Henry Creek, mi. S Gandy, Millard Co., Utah. June 13 imm.♀ in back of Mr. Parker's house. These were in the act of raiding his grain store. According to Mr. Parker, the ranchman, they were constantly making trips back and forth from their holes under the corral fence to the grain house. Those shot had their cheek pockets distended with oats. Although there was a large sack of poisoned barley in the storehouse the Ammos. would not seem to touch it. Because of this the rancher was quite baffled as to how to control the squirrels. I tried to help him by telling him various means of control. The squirrels were quite tame. They would allow me to approach within several feet of them. At one time I sat and watched them from a vantage point near the main route from corral to feed house. They would approach cautiously — watching me all of the time until about halfway between the two places. Then they would run rapidly the remaining distance as if they knew that it would be foolish to attempt to retrace their steps after venturing as far as they had.
