A female fox, or vixen, is most active when much of the human world sleeps. This factual account follows Vixen through winter and on into spring as she hunts, meets with her mate, escapes chasing dogs, and explores abandoned burrows of other animals. Vixen stays in her den more and more as spring nears, her mate bringing food. In late spring, when she emerges to hunt, she is followed out of her den by four kits. The kits learn from their parents through the summer and by fall are ready to set off on their own. The drama is unforced and genuine in a lyrical narrative that never anthropomorphizes its subjects. Realistic pastel paintings convey both the wildness of the foxes and their proximity to humans. A note provides more information about the red fox. (Ages 6-9)
