If a tick bites an infected mouse, that tick will then also be a carrier of Lyme, therefore a reduction of mice in an area can mean a reduction in Lyme disease-carrying ticks. Rodents, like mice, can be carriers of the bacteria that cause Lyme disease. They can also regulate populations of rodents, which aids in the reduction of Lyme disease within the landscape. As highly mobile animals, red foxes act as dispersal agents for many plants. Red foxes can greatly enhance the ecosystems they inhabit. Benefits of Red Foxes to Nature and Society Ecological Red foxes reach sexual maturity within the end of their first year. By September or October, the young foxes disperse to find their own home ranges. Parental care continues until the juvenile foxes reach adult size at 6–7 months of age. At three weeks of age, the kits can begin to walk and may emerge from the den (Figure 3). ![]() Kits begin eating solid foods after being weaned from their mother’s milk between 8–10 weeks after birth. During rearing, the vixen stays in the den and tends to the kits while the male fox gathers food and returns it to the den for his mate and offspring. In suburban areas, foxes commonly den under backyard porches and decks. They may also burrow under fallen trees or use large tree cavities. Foxes will dig dens in loose soil or sand, often expanding burrows used by other smaller mammals. In the spring before the vixen gives birth, the mated pair selects a den location for rearing the kits. Litter size is thought to be directly correlated with the availability of food, with most litters ranging from 3 to 7 kits, which are born in early to mid-Spring. The breeding season in New Jersey and other temperate regions occurs during January and February. Unpaired foxes seek out a mate in mid to late fall. Where food resources are plentiful, a single male fox (dog) may maintain a larger territory and mate with multiple females ( vixen). Most red foxes are monogamous and maintain a breeding relationship for life. Life Historyįigure 3: Red fox kits exploring outside the den. When available, fruit can make up a significant portion of a fox’s diet. In addition to live prey, red foxes also consume eggs of birds and reptiles, and they are opportunistic scavengers of human resources, such as food waste and agricultural products. Their relatively large ears allow them to hear and capture prey hidden deep within leaf litter, thick vegetation, or even snow. Red foxes are capable hunters of both small mammals (i.e. Their diet can vary significantly across seasons depending upon food availability. Red foxes are omnivorous, feeding on a wide variety of animals and plants. Territorial behavior includes scent marking and using excrement to denote territory boundaries. Males can be territorial, particularly when resource availability is low, such as during winter months. Red fox home range sizes vary drastically depending on habitat type and resource availability, but they typically range from 2 to 8 square miles. This advantage has allowed for long range expansions across North America over the past 200+ years. In fact, red foxes are capable of dwelling in almost any setting with adequate food resources. Though they are native to the old growth forests of Europe and North America, red foxes are now found in most habitat types, including significantly human-modified landscapes (Figure 2). Red foxes have nonretractable claws much like their canid cousin, the domestic dog. Other fur phases are more common in colder regions of North America and include black, silver, and a cross-phase in which the fox exhibits dark greyish-brown fur with a darker cross pattern across its shoulders. The most common within New Jersey is the signature bright red to orange coat with a white underside. North American red foxes can exhibit one of four coloration patterns ( phases). Males tend to be approximately 10% larger than females. Red foxes are larger than grey foxes but smaller than eastern coyotes, weighing an average of 7–15 lbs. Red foxes are typically bright red to yellowish-red in color and always have black legs, black-tipped ears, and a white-tipped tail (Figure 1). These species are often misidentified due to their similar ‘doglike’ appearance and color variations, as well as the low-light conditions of the dusk to dawn ( crepuscular) hours in which they are typically seen. There are three wild Canidae species that occur in the eastern United States: red fox, gray fox ( Urocyon cinereoargenteus), and eastern coyote ( Canis latrans). Red foxes belong to the taxonomic family Canidae, which includes foxes, wolves, coyotes, jackals, and dogs. ![]() Figure 1: Typical coloration of a red fox, exhibiting the black ear tips and feet, with white tipped tail.
