Harold Child Bryant, The Common Ground Squirrels of California (1912)

“ Ground squirrels have relatively large ears and eyes, longer tails, and the cheek pouches do not open externally ; most of them are larger in size, diurnal, and forage for food above ground. The burrow of the pocket gopher can be distinguished by a mound of earth surrounding the entrance, and by the fact that the opening is nearly always kept plugged full of earth. The burrow of the ground squirrel on the other hand is usually open, with the excavated earth thrown out on one side of the entrance only. ”

“ These ground squirrels usually live in colonies, their burrows often being connected for a considerable distance. Food in the shape of grain, seeds, and fruit is stored for the winter season. The call note is a single loud whistle. The warning note is a similar short whistle followed by two or three chattering trills. Young, numbering from five to ten, are usually born in March and April. This ground squirrel has been found infected with bubonic plague, and several cases of human plague have been traced to a bite of one of these animals. ”

“ Pour in the poisoned starch over the barley and stir rapidly until the poison is evenly distributed; then allow the grain to dry. When dry it will keep indefinitely without deterioration. By this method a coating of poison is formed on the outside of the grain, which acts much more quickly than if the grain is boiled or soaked in the poison. Squirrels are also readily killed by carrying such coated grain in their cheek pouches while storing food for future use. ”

“ The other, the ground squirrel (Citellus sp., Ammospermophilus sp., Callospermophilus sp.) is especially destructive to grain, but it is also destructive to nuts and fruit. The established fact that the California ground squirrel is instrumental in spreading bubonic plague has made these animals of more than ordinary economic importance.
These two principal rodent pests are easily distinguished by their general appearance, size, habits, and burrows. The pocket gophers have very short ears, small eyes, short tails, and cheek pouches which open externally ”

“ A small striped form belonging to another genus (Ammospermophilus) is found to a limited extent in the San Joaquin Valley, and a variety of the same species in the rocky places in the deserts and foothills bordering the deserts. ”

“ Where the area is extensive the poison may first be used, because of its cheapness, and this followed in the proper season with the carbon bisulfid to clean up those that escape the poison.
Small areas may be freed from squirrels, but these are likely to be quickly reinvested again from the neighboring territory. It is often important, therefore, for the people of a district to unite in a coöperative campaign and free large areas from the squirrel pest.

“ These forms are known as the Nelson ground squirrel and the Antelope ground squirrel. Neither are abundant enough to be of great economic importance. Golden-mantled ground squirrels (Callospermophilus sp.) , more often called red-headed chipmunks, are mountain species and seldom give trouble (Fig. 2) .
CONTROL OF GROUND SQUIRRELS.
H. J. .
There are two methods of destroying ground squirrels: first, by means of poisoned grain, and, second, by the liberation of carbon bisulfid in their burrows. ”
