What is the primary diet that dictates the location of weasels across North America?
Answer
Small rodents
The survival and territorial location of weasels are intrinsically linked to the steady supply of their primary food source, which consists exclusively of small rodents. This necessity means that even if other ecological factors seem favorable, a weasel will not establish a territory or remain long in an area if the population density of creatures like mice, voles, or ground squirrels is insufficient to support their daily caloric needs. This dietary requirement heavily influences their habitat selection, pushing them towards environments where these small mammals thrive, such as fields, grasslands, or areas near rodent burrows.
