[11][13][14] Near the northern limit of the southern flying squirrels distribution, home range increases in size as mast-producing trees become more dispersed. [8] Additionally, they often aggregate together in dens, especially as seasonal temperatures decline[18][19] in order to conserve energy. [11] Male home ranges contain more food as they have been associated with a higher than expected number of large red oaks and white oaks, whereas female home ranges contained lower food resources and more abundant nesting sites possibly to avoid contact with other squirrels while raising the young. I saw 2 (maybe 3) in about 3 hours there in June 2014. home range varies between one and one hundred acres, depending on season and food availability. (2011). Range. (1968).
