"Citellus townsendii" 3 mi. W and 1 mi. N Kennewick, 375 ft., Benton Co., Washington May 16, 1940. A colony of these Ground Squirrels are in a 10 acre field near the river. The ground is a level piece with a few scattered rose wild rose bushes growing on it, and some grass. The rancher nearby grazes his sheep on the area and keeps the grass rather short. When the colony was first seen about eight or nine squirrels were seen standing up near their burrows. after trapping, with rat traps, about 20 of these animals, none were seen standing in the field. The squirrels taken were very fat and I believe the adults were ready for aestivation. Some of the burrows appeared to be inactive and possibly some of the adults have already hibernated. Some of the area all squirrels seen on this side of the river are in this colony. We have covered a good deal of country setting Laphor traps but no squirrels take burrows were noted except in this one locality.
