The size of the home range of southern flying squirrels varies greatly. [14] Average home range estimates are 2.45 hectares, [14] 9.0 hectares, [15] and 16.0 hectares [12] for adult males, 1.95 hectares, [14] 3.9 hectares, [15] and 7.2 hectares [12] for adult females, and 0.61 hectares for juveniles. [14] Significant overlap exists among the ...
This ground squirrel's home range is two to three acres (0.8 to 1.2 ha). Late in life, naturalist John James Audubon made a final expedition to the western plains in search of four-footed mammals. These striped ground squirrels would be tempting prey for many birds, especially hawks and owls.
Subadult males had spring home ranges of about 27 acres (11 hectares), and adult females had somewhat larger summer home ranges than adult males. [17] Patton reported the ranges of three squirrels as 10, 30, and 60 acres (4.0, 12.2, and 24.4 ha) in Arizona. [18] Hall reported the home range of an adult female as 29 acres (12 hectares). [19]
Western gray squirrel's range The western gray squirrel ( Sciurus griseus ) is a tree squirrel found along the western coast of the United States and Mexico.

The American red squirrel is variously known as the pine squirrel or piney squirrel, North American red squirrel, chickaree, boomer, or simply red squirrel. The squirrel is a small, 200–250 g (7.1–8.8 oz), diurnal mammal that defends a year-round exclusive territory.
In North Dakota, males have an average home range of 24 hectares (59 acres) and females 9 ha (22 acres), although the home ranges of individual squirrels do overlap, and population densities can range from 1.3 to 2.5 per hectare (0.53 to 1.01/acre). In the winter, several individuals can share the same burrow.
