Blandford's fox

Features

Geographic Range

Vulpes cana , Blanford's fox, is found from Israel throughout the mountainous regions of the middle east to Afghanistan. The range of this species likely covers all the middle-eastern countries, although populations may be discontinuous. They are known from Iran, Pakistan, Afghanistan, Turkistan (Kazakhstan), Israel, Oman, United Arab Emirates, and Saudi Arabia, and are expected to occur throughout a wider range, including Eritrea, Sudan, and Yemen.

Habitat

Vulpes cana is found in semi-arid steppes and mountains. This species prefers areas with steep, rocky slopes, cliffs, and canyons. Historically, Blanford's foxes were considered to avoid hot lowlands as well as cooler uplands. However, they have been observed near the Dead Sea in Israel, where they are found in cultivated areas where melons, Russian chives, and seedless grapes are grown. Blanford's foxes occur up to elevations of about 2000 meters. The most important habitat feature for Blanford's foxes seems to be the presence of dry creek beds. Dens are chosen in areas with large rock piles.

Physical Description

Blandford's foxes are small foxes with large ears and long, bushy tails with long, dark guard hairs. They range in mass from 1.5 to 3 kg, and in head to tail length from 70 to 90 cm (tail mean length is 323 mm, body mean length is 426 mm. Males and females are similar in appearance. The snout is slender. Vulpes cana has cat-like movements and appearance. Coloration is black, brown, or grey, and is sometimes blotchy. The flanks are lighter than the back, which has a black stripe running down it, and the underside is yellow. The tip of the tail is usually dark but can be white. Males have 3 to 6% longer forelegs and bodies than females.

Development

See Reproduction.

Reproduction

Vulpes cana is monogamous.

Blanford's foxes typically mate from December to February. They are strictly monogamous. The gestation period is 50 to 60 days, after which the female gives birth to a litter of 1 to 3 kits. The altricial young are nursed for 30 to 45 days. Young become sexually mature between 8 and 12 months of age.

Females nurse their young for 30 to 45 days. Young are dependent on their mothers until they can forage on their own. Foxes have relatively altricial young, and usually give birth to them in a secluded den, where they can develop under the care of their mother. Because the mating system of Blandford's foxes is monogamous, and breeding pairs maintain minimally overlapping ranges, the male may also be considered to provide some care to the offspring, even if only in the form of maintaining an area from which food is supplied. Males have been observed grooming juveniles. Young remain in their natal range until the October or November in the year of their birth.

Lifespan/Longevity

Average lifespan of Blandford's foxes is 4 to 5 years, and does not exceed 10 years in the wild. Old age and rabies are the primary recorded causes of mortality.

Behavior

Blanford's foxes are strictly nocturnal, solitary hunters. They do not exhibit a change in their daily activity with season. They generally become active soon after dusk and are active throughout the night.

In Israel Blanford's foxes occur at population densities up to 2 per square kilometer. They are one of the few fox species to regularly climb, scaling cliffs with ease. Their especially long tail is used as a counter balance when jumping and climbing.

Home Range

Foraging home range averaged 1.1 square kilometers, plus or minus 0.7 square kilometers. Monogamous pairs occupy territories of 1.6 square kilometers, with little overlap between territories.

Communication and Perception

Like other canids , Blanford's foxes have keen eyesight, sense of smell, and hearing. They communicate with chemical cues and with vocalizations.

Food Habits

Blanford's foxes are omnivorous, eating mostly insects and fruit. Prey includes insects such as beetles, locusts, grasshopper, ants, and termites. Primary wild fruits eaten are two species of caperbush ( Capparis cartilaginea and Capparis spinosa ), Phoenix dactylifera , Ochradenus baccatus , Fagonia mollis , and Graminea species. Fecal samples have up to 10% vertebrate remains as well. In Pakistan they have been recorded eating agricultural crops, including melons, grapes, and Russian olives.

Blanford's foxes hunt alone the majority of time. Even mated pairs tend to forage independently. They rarely cache food.

Blanford's foxes seem to rarely drink water, meeting their water needs through the foods they eat.

Predation

The main predator of these foxes is humans, although one case of a Blanford's fox being killed by a red fox ( Vulpes vulpes ) has been recorded. Blanford's foxes are not hard to catch, showing little fear of traps or humans.

Ecosystem Roles

Blanford's foxes help to control rapidly growing small mammal populations by preying on mammals such as rodents. They may have a similar effect on insect populations. Because they are frugivorous, they likely play some role in dispersing seeds.

Economic Importance for Humans: Positive

The pelts of Blanford's foxes are valuable and they are hunted. Because of their diet, this species probably controls rodent and insect populations which might have a negative impact on crops.

  • Positive Impacts
  • body parts are source of valuable material
  • controls pest population

Economic Importance for Humans: Negative

Blanford's foxes cause domestic crop damage in some areas.

  • Negative Impacts
  • crop pest

Conservation Status

Trapping and hunting have caused a large decline in the numbers of these foxes. They are protected throughout Israel, as the majority of their habitat is in protected areas. Development in other parts of their range may pose a risk to populations.

Other Comments

Mitochondrial DNA evidence suggests that Blanford's foxes and fennec foxes are sister taxa.

Living on the ground.

desert or dunes

in deserts low (less than 30 cm per year) and unpredictable rainfall results in landscapes dominated by plants and animals adapted to aridity. Vegetation is typically sparse, though spectacular blooms may occur following rain. Deserts can be cold or warm and daily temperates typically fluctuate. In dune areas vegetation is also sparse and conditions are dry. This is because sand does not hold water well so little is available to plants. In dunes near seas and oceans this is compounded by the influence of salt in the air and soil. Salt limits the ability of plants to take up water through their roots.

tropical savanna and grassland

A terrestrial biome. Savannas are grasslands with scattered individual trees that do not form a closed canopy. Extensive savannas are found in parts of subtropical and tropical Africa and South America, and in Australia.
