The Island foxes scavenge for food during the early evening, although their lifestyle allows them to be up and about anytime in a 24-hour day. The foxes live in troops that range in number, and it directly correlates to the size of the territory they inhabit. Other factors of territory size include the average age of the foxes in the troop as well as which gender holds the majority in number. The foxes generally communicate via sight, smell, and hearing, as they use scents to mark their territory and barking and yipping to alert one another. The foxes vary in comfortability around the human race, as they react to the acceptance of their presence near and around human habitats. Their behavior around potential threats is always in the interest of self-preservation, so tendencies of foxes around more hostile human cities and towns are to be generally more timid and evasive, and vice versa in areas such as campgrounds where interaction is a common occurrence.
