Belding's ground squirrels do not keep food in caches. Instead they store fat reserves. [4] [7] As such, the ground squirrels may eat a great amount of food before hibernation. They must spend as much as 40% of the summer eating. [7] When eating, the ground squirrel feeds itself with its front paws while standing on its back paws. [7]
Tree squirrels undergo a complete head-to-tail molt in the spring and a rump-to-head molt in the fall. Tail hair is replaced only in the spring. Nesting mothers will use their tail hair to line birthing nests. Western gray squirrels eat berries, nuts, a variety of seeds, and the eggs of small birds.
They can weigh from 280 to 738 g (9.9 to 26.0 oz). [7] The tail is relatively bushy for a ground squirrel, and at a quick glance, the squirrel might be mistaken for a fox squirrel. [8] As is typical for ground squirrels, California ground squirrels live in burrows, which they excavate themselves. Some burrows are occupied communally, but each ...
An unexpected shift in squirrel behavior. Smith and her colleagues observed the squirrels’ meat-eating behavior during a study period from June 10 to July 30.

[1] The squirrel was first described in 1886 by Frank Stephens of San Diego. [2] It is listed as a threatened species under the California Endangered Species Act, but not under the federal Endangered Species Act.
