Edward William Nelson, Wild Animals of North America
“ The vivacity and hearty enjoyment of life by the occupants of a prairie-dog “town” is most entertaining to an observer. With the first peep of the sun above the horizon they are out on the mounds at the entrances of their burrows, first sitting erect on their hind feet and looking sharply about for any prowling enemy. If all is well they begin to run about from one hole to another, as though to pass the compliments of the day, and scatter through the adjacent grassy feeding ground. ”
