Right now (mid-July) is prime time to shoot Belding's and Townsend's ground squirrels in the western high desert (Eastern Oregon, Idaho, high NorCal). Most alfalfa fields are cut or being cut, so they are fully exposed. The juveniles are out of their holes trying to get fat for hibernation in August/September. Check with your farmer friends to see if they've finished baling (equipment off the fields) before you head out. And wherever there are ground squirrels, there are badgers as well, so bring a centerfire rifle as well.
