The nests are used year-round by most Abert's squirrels for nightly shelter, [27] although females often move the litter to a larger nest when the young are 3 to 6 weeks old. [5] In winter, pairs of Abert's squirrels, usually an adult female and one subadult (presumed) offspring, use the same nest for shelter. [5]
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).

Single wolves or mated pairs typically have higher success rates in hunting than do large packs; single wolves have occasionally been observed to kill large prey such as moose, bison and muskoxen unaided. [1] [2] This contrasts with the commonly held belief that larger packs benefit from cooperative hunting to bring down large game. [2]
