Because the response of California ground squirrels to different baits varies with changes in the location , time , and mode of bait application , a solid understanding of ground squirrel foraging behavior is necessary for the development of effective , reduced risk baiting strategies . It has been...
Post the squirrel stands on its hind legs with its back erect or semi-erect and forelimbs off the ground. At least three surveys were conducted for each female during gestation, at least three during lactation, and at least two during the post-emergence period. Focal animals were observed fo...

However, previous behavioral observations suggest round-tailed ground squirrels have a clustered matrilineal structure with a suite of social behaviors, suggesting that they may represent a unique outlier in ground squirrel sociality models. Within the population of round-tailed ground squirrels at the ...
Scent-marking is a frequent behaviour of highly social ground squirrels and might play an important role in their social dynamics. Female Columbian ground squirrels exhibit considerable scent-marking during the reproductive period. We examined how gestating and lactating females responded to jugal gland ...
