Xerus: Fascinating Ground Squirrel of Africa
Introduction:
Sometimes called the ground squirrel, this animal is a marvel of adaptation. They are highly resourceful and nimble when it comes to foraging and surviving in the harshest environments on earth. Being social animals, they live in highly organised colonies that exhibit remarkable behaviour, thereby enhancing their chances of survival. Their peculiar traits, high intellects, and role in nature make Xeruses an example of God’s immense creativity.
Amazing Facts:
- Sun Protection: The bushy tail enables them to cover themselves from the scorching heat in desert regions.
- Burrow Architects: It is not just some hole dug on the ground; xerus burrows have intricate designs that provide shelter as well as protect against extreme temperatures and other predators.
- Efficient Water Use: Xeruses get most of their water from food which saves them from thirst especially during dry seasons.
- Social Creatures: These creatures usually exist in colonies comprising up to twenty members which safeguard each other against any harm.
- Super Fast: These ground squirrels are extremely fast, they can run up to 15 miles per hour to escape from predators.
- Sound the Alarm: Xeruses communicate with their tails and voice calls to warn others of approaching danger.
- A Variety of Diets: They fall back on eating seeds, fruits, insects, and at times small vertebrates because they are omnivorous.
Habitat and Diet:
Habitat:
Native to Africa, they live in dry environments like:
- Deserts: Arid regions such as Kalahari and Namib deserts are home for them.
- Savannas: They also reside in grasslands and open woodlands.
- Rocky Terrain: They love rocky areas where they can find cover or vantage points.
Diet:
They are opportunistic feeders, consuming a wide range of foods to sustain themselves.
- Seeds/Nuts: Seeds primarily form part of their staple diet, which is usually available all over where they live.
- Fruits: Fruits make up some of their diets whenever xeruses have access to them.
- Insects: These can be ants, termites, or other small invertebrates that they feed on.
- Small Vertebrates: The occasional prey of small reptiles or mammals is xeruses to meet their protein needs.
Appearance:
They are medium-sized rodents with a sleek and agile build, perfectly suited to their environment. Important traits include:
- Coat: Ranging from sandy brown to grey, their fur is short and coarse so as to help them blend into the environment.
- Tails: It trails behind in a tufted manner for balance, communication, and shade.
- Length: On average, the body length measures 9-12 inches, with tails contributing an extra 7-10 inches.
- Eyes: dark eyes that are big enough that they can spot predators easily using this vision advantage.
- Paws: With strong curved claws, they can dig burrows and search for food effectively.
Species and Subspecies of Xeruses:
They belong to the genus Xerus, which has four main species:
- Cape ground squirrel: Endemic to southern Africa, especially the Kalahari desert areas.
- Striped ground squirrel: Occurring throughout western & central Africa; notable for its distinctive dorsal stripes.
- Mountain Ground Squirrel: Found in rocky areas of southern Africa and well adapted to low temperatures.
- Unstriped Ground Squirrel: Lives in eastern Africa with fur that is devoid of stripes.
Predators and Threats:
Natural Predators:
The various natural predators that they face in their habitats include:
- Birds of Prey: Eagles, Hawks, and Owls are all known for hunting these species too.
- Carnivores: Jackals, foxes, and wildcats are some common enemies.
- Snakes: Pythons and Cobras can be a major threat, especially when it comes to young squirrels.
Threats:
To counter these threats, They rely on several strategies:
- Burrow Safety: They run into their holes when danger strikes.
- Vigilance: Constant scanning of their surroundings helps them detect predators early enough.
- Group Defence: Alarm calls as well as tail displays are used by members to fend off predators together.
Mating and Reproduction:
The fascinating reproductive cycle of this animal enables preservation of its kind.
- Breeding Season: Mating takes place within specific seasons commonly occurring after rains when food is plentiful.
- Gestation: The female gestation period lasts only for about 48 days.
- Litter Size: They give birth to one to three young per litter.
- Parental Care: Young ones are nursed by females in underground burrows for warmth and safety.
How do they Communicate?
They are highly social animals with complex communication methods, including:
- Vocalisations: Different sounds such as chirping, squeaking, and growling indicate warning signals or calls for mating.
- Tail Movements: Their tails speak of aggression, alertness, or submission through position and movement.
- Body Language: Their mood and intention can be seen from postures and movements they make.
Religious and Cultural Significance:
They play a vital role in their ecosystems and hold cultural importance.
- Ecosystem Engineers: They cultivate the soil through their burrowing action, promoting plant growth and housing other organisms inside the pores created in the ground, as well as other animals that seek refuge there.
- Seed Dispersers: They eat seeds, planting some of them elsewhere, hence contributing towards the regeneration of vegetation cover.
- Cultural Symbolism: Some African cultures consider xeruses as an emblem of adaptability or resourcefulness.
Movies featuring Xeruses:
Xeruses may not have the popularity of some other animals, but they are sometimes seen in nature documentaries and educational programs that showcase their unique behaviours and adaptations as well. These includes,
- The Lion King (1994): The colourful Pride Lands, although it does not exactly showcase a xerus, does include other small mammals that comprise the beauty of African fauna.
- Madagascar (2005): The animated movie does revolve around zoo creatures, but animals like rodents and other such smaller fauna add to the quirks that come with the island’s wildlife.
- Planet Earth II (2016): This documentary series exhibits various animals living in the desert, xerus being one of them, in its episode called ‘The Deserts’ along with their methods of coping in extreme conditions.
- The Wild (2006): Set in Africa, this animated film includes small mammals such as the xerus as part of the rich wildlife diversity in Africa.
