Bat-eared fox. |
The bat-eared fox is an African
species of fox who is found living across the savannahs of the southern and
eastern parts of the continent. It is so called because of its very large ears
which are up to an impressive 12cm (4.7 inches) in size and full of blood
vessels to clear the heat and keep cool. These big ears also give the fox
really good hearing.
This African fox is small and cute,
weighing only up to 5kgs, and measuring 55cm in length including both its and
body while its bushy tail adds on 23 - 34cm. Their small faces are very
characteristic with a racoon-like ‘’face mask’’ black in colour and muzzles
short and pointed. Bat-eared foxes have short legs and strong paws adapted for
digging their dens.
Their fur is a yellowish-brown to sandy grey colour, with their bellies being lightest in colour and the fur around their eyes, muzzle, back of ears, legs and tips of their tails darker. Wild animals such as hyenas and birds of prey hunt them down for food while humans hunt them for their fur.

Habitat
There are two species of bat-eared
foxes that roam East and southern Africa. One lives from Ethiopia and South Sudan
to Tanzania, the other is found from southern Zambia and Angola to South Africa
as well as extending to Mozambique and Zimbabwe. Bat-eared foxes are native to
10 countries on the African continent and their homes range in size from 0.3 to
3.5 km2.
Bat-eared foxes prefer areas of
bare ground with low shrubs and short grasses to live and forage for their
food. However they do venture into areas of thick shrubs and tall grasses to hide
out when feeling threatened.
They raise their baby foxes in dens
they dug out themselves as protection from extreme weather. Bat-eared foxes
also enjoy relaxing under acacia trees in South Africa during the day, seeking
shade and protection from the harsh African sun.
Behaviour
Bat-eared foxes live in breeding pairs or family groups of up to 15
individuals which include mating pairs with their young. Being highly social
animals they are often groom one another, play together and sleep in their protective
groups. They use visual displays such as facial expressions, ear and tail
posture as a means to communicate among each other. These foxes will also call
out to one another making a shrill cry.
Males are called ‘dogs’ and females are
referred to as ‘vixens’ while their young are called ‘kits’, ‘cubs’ or ‘pups’. The
males are the guards of the groups and make for great fathers as they groom and
play with the youngsters while the mother searches for food for her family.

These African foxes are mostly
nocturnal but sometimes are out and about during the day, this depends on their
location of the time of the year. They prefer to feed under the cover of nightfall,
emerging from their underground dens at dusk, to feast in their groups.
Diet
Bat-eared foxes have a mostly insectivorous
diet, eating grasshoppers and termites, although sometimes birds, eggs,
rodents, lizards, reptiles and wild berries found in their surroundings. Their
diet consists of an extraordinary number of 1.15 million termites a year which
is in total 80% of their diets. They seldom drink water as they gain most of
the moisture needed form their food.
They have extremely pointed teeth
with which to quickly and efficiently chew their food and which in turn helps
to digest their meals. Their teeth are also small and they have up to 8 extra
molars which grind the hard casings of the insects they chomp down.

Reproduction
These foxy animals form monogamous
pairs and breed each year having a litter of three to six. After carrying their
developing young for 6 - 70 days, she gives birth to the litter in the safety
of their den. Both mother and father take responsibility for the litter, by taking
care and protecting their youngsters.
Just 9 days after birth the young
cubs open their eyes and from 17 days of age they begin to explore the outside
world leaving the den for adventure. At 1 month old the litter begins to wean
off from their mother but continue to suckle until 3 or 4 months old. Young
bat-eared foxes are considered fully grown when they reach 5 to 6 months old
and are ready to form their own family when just 9 months old.
Most young foxes leave their family
groups or parents to form with another group or make a pair although some
females do remain with their native group.
Sadly the mortality rate in litters
are high and often the entire litter born does not survive. This is due to
several factors such as the fact that the mother only has four nipples while
sometimes giving birth of up to 6 cubs and the danger of predators grabbing the
young.
Did you know?
They have up to 48 teeth, more than
any other non-marsupial mammal.
Bat-eared foxes are hunted by birds
of prey, jackals and sadly humans for their fur.
