About Vulpes chama (A.Smith, 1833)
Common Name and Taxonomic Grouping
Vulpes chama, also called the Cape fox, is a small canid.
Body and Tail Length
Excluding the tail, its body length is usually between 45 and 62 cm (17.5 to 24.5 in), while its tail measures 30 to 40 cm (12 to 15.5 in).
Shoulder Height and Weight
It stands 30 to 35 cm (12 to 14 in) tall at the shoulder, and weighs between 2.5 and 4.5 kg (5.5 to 9.9 lb).
Skull Morphology
Its skull is very similar to that of Vulpes bengalensis, though the cranium of V. chama is slightly wider and its maxillary region is slightly shorter.
Head Features
It has relatively large, pointed ears and a small, pointed muzzle.
Fur Coloration of Head and Ears
Its fur is silvery-gray, with tawny color on the back of the ears; white hairs appear around the center of the outer ear (pinna).
Neck, Side and Underpart Coloration
The neck and sides are lighter in color, and the underparts range from pale tawny to pale buff.
Facial Markings
The head is dull red, the lower jaw is dark brown, and there are white markings on the throat.
Leg Coloration
The legs are more tawny than the rest of the body.
Tail Appearance
The tail is dense and bushy, and can be silvery, pale fawn, or buff with a brown or black tip, or dull yellow.
Tail Markings
The tail tip is always black, and there is a dark spot over the caudal gland.
Underfur Characteristics
The fur is soft, made up of a thick, wavy underfur that is around 25 mm (1 in) long.
Guard Hair Characteristics
The underfur is covered by a dense layer of guard hair that is less than 40 mm (1.6 in) thick.
Molting Period
Molting happens during the wet season, from October to November.
Sexual Dimorphism
V. chama shows little to no sexual dimorphism.
Genus Distribution Distinction
It is the only species in the genus Vulpes that lives in Africa south of the equator.
Habitat Types
It primarily lives in arid and semi-arid areas, but it can also be found in areas with higher rainfall and denser vegetation, such as the fynbos biome of the western Cape Province of South Africa.
Northern Distribution Range
It is widespread across the central and western regions of southern Africa, ranging as far north as 15 ° N in south-western Angola.
Distribution in Southern Africa Mainlands
It is widespread in Zimbabwe, Botswana, and South Africa, where it occurs across most of the Western and Northern Cape provinces, the Eastern Cape (excluding its southeastern side), the Free State, western and northwestern KwaZulu-Natal, and the North-West province.
Distribution in Lesotho
It also occurs in Lesotho, a high mountainous region.
Breeding Season Timing
Its breeding season falls in July and August, which is winter in the southern hemisphere.
Mating Pair Bonding
Monogamous pairs may form during this time, but the duration of pair bonds and whether they persist from year to year is not well understood.
Adult Pair Interactions
Paired adults generally only interact during the mating season, though they do perform greeting behaviors including mouth sniffing, nuzzling, and body slamming.
Gestation and Litter Size
Female Cape foxes have a gestation period of 51 to 53 days, and give birth to litters of 1 to 6 cubs (also called kits).
Newborn Cub Weight
Cubs typically weigh between 50 and 100 g (1.8 to 3.5 oz) at birth.
Cub Den Usage
Cubs are reared underground in burrows, and stay close to the den until they are about four months old.
Den Sharing Behavior
Multiple females may simultaneously share the same den.
Weaning and Foraging Onset
Cubs are weaned at around six to eight weeks of age, but do not start foraging until they are four months old.
Cub Daytime Behavior
They often play outside the den during daylight hours.
Parental Care Behavior
Both parents care for the young; the male provides food for the female for at least 1–2 weeks after birth.
Cub Independence and Dispersal Timing
Cubs typically become independent at between 5 and 11.5 months of age, when they disperse, usually in June or July.
Dispersal Distance
Juveniles may disperse 7–22 km (4.3–13.7 mi) from their natal den, while females may stay within their natal range.
Subadult Food Stealing Behavior
Some subadult Cape foxes steal food that the parents bring to the cubs at the den.
Family Group Structure
A family group usually consists of the parents and their offspring, but different family groups sometimes mix while feeding.
Multiple Litter Behavior
Multiple litters in a single female are possible and have been observed; however, when a female is expecting another litter, she usually chases the cubs from her previous litter out of the den.
Growth and Maturity Timing
Cape foxes reach full size within about a year, and both females and males reach sexual maturity at 9 months old.
Life Expectancy
The Cape fox has a life expectancy of about six years, and can live up to 10 years.
