Abstract

The Franklin ground squirrel (Spermophils franklinii) is common in central Nebraska in low-lying areas of silty soil overgrown with Bromzls inermix, which provides concealment and nest material for the squirrels.The burrows range from simple to complex in structure but seldom vary in depth (17 inches) and diameter (31/4 inches). Emergence from hibernation in 1969 and 1970 was in early May and, thereafter, the daily activity occurred predominantly about 4 and 7 hours after sunrise and 5 hours prior to sunset. Weather conditions did not seem to affect the daiIy life patterns of S. Iranklinii.
