The tejón, also known as the white-nosed coati (Nasua narica), is a unique and intriguing mammal native to the Americas. With its long snout, bushy tail, and intelligent eyes, the tejones are often mistaken for a raccoon, though it belongs to the same family, Procyonidae.
This adaptable creature thrives in forests, grasslands, and even mountainous regions, making it one of the most widespread mammals in its range. Despite its distinctive appearance, the tejón remains relatively unknown to many outside its native habitats.
This article examines this remarkable animal’s biology, behavior, habitat, diet, and conservation. Whether you’re a wildlife enthusiast or simply curious about the animal kingdom, this exploration of the tejón will provide fascinating insights into its role in nature and its survival strategies.
Physical Characteristics
The tejón possesses several unique features that help it navigate diverse environments. Its elongated snout is highly sensitive and helps it locate food buried underground. Its clawed front paws allow it to dig and manipulate objects skillfully.
Here are some key physical traits of the tejón:
- Size: Adults range between 33 to 69 cm (13 to 27 inches) in body length. The tail adds 30 to 60 cm (12 to 24 inches).
- Weight: Males are significantly larger than females, weighing between 4.4 to 18 pounds (2 to 8 kg), while females range from 3.1 to 9 pounds (1.4 to 4.1 kg).
- Fur color: Their fur varies from reddish-brown to dark brown or black, with lighter tones on the underside.
- Distinctive markings: They have a white facial mask and a white patch on their snout, which gives them the name “white-nosed coati.”
- Tail: The tejón’s long, bushy tail is often held upright and is used for balance when climbing.
Unlike raccoons, which are nocturnal, tejones are diurnal, meaning they are active during the day. Their excellent climbing skills make them well-suited for both tree-dwelling and ground foraging.
Social Behavior and Communication
Tejones have a complex social structure, particularly among females and juveniles. Unlike many solitary mammals, tejones form large social groups, sometimes consisting of up to 25 individuals.
Group Dynamics
- Females and young tejones live in groups called bands, cooperating in foraging and protecting their young.
- Adult males, however, are typically solitary, only joining groups during the mating season. Because of this, they are sometimes called “solitary boars.”
Communication
Tejones communicate using a range of vocalizations, body movements, and scent markings. Some of their vocal signals include:
- Chirping and whistling to maintain contact within the group.
- Snorts and grunts when foraging or playing.
- High-pitched alarm calls to warn others of approaching predators.
Their scent glands near their tails help mark territory and strengthen social bonds.
Diet and Foraging Habits
Tejones are omnivorous, meaning they eat both plant and animal matter. Their diet changes depending on seasonal availability, making them adaptable to different environments.
What Do Tejones Eat?
Their diet includes:
- Insects and invertebrates – Tejones use their long snouts to sniff out beetles, spiders, and larvae hidden in the soil.
- Fruits and berries consume various fruits, including bananas, figs, and mangoes.
- Small vertebrates – Occasionally, they hunt lizards, birds, and rodents.
- Eggs – They raid bird nests for eggs, an excellent protein source.
Because of their diverse diet, tones are essential in controlling insect populations and spreading seeds, helping maintain ecological balance.
Reproduction and Life Cycle of the White-Nosed Coati
Mating Season and Reproductive Behavior
The mating season for white-nosed coatis typically occurs during the late spring or early summer. During this time, solitary males, known as “coatimundis,” seek out female groups, called bands, which consist of adult females and their young. The dominant male within the group mates with multiple females.
Males attract potential mates through vocalizations and scent-marking, and they often engage in courtship behaviors like grooming and following the females closely. However, once mating is complete, males are driven away from the group to prevent potential aggression toward offspring.
Gestation Period and Birth of Offspring
After mating, a female coati experiences a gestation period of approximately 75 to 77 days. As birth approaches, she separates from the group and builds a nest high in the trees or in dense vegetation to keep her young safe from predators.
A typical litter consists of two to six babies, called kits or pups, which are born blind and completely dependent on their mother. During the first few weeks, the mother stays with her offspring, nursing and protecting them from threats.
Growth Stages and When Juveniles Become Independent
At around three weeks old, the young coatis begin to open their eyes and show early mobility. By the time they are four to five weeks old, the mother returns to the band with her kits, where they are welcomed and raised in a communal setting with the help of other females.
The juveniles become fully weaned at about four months of age but continue learning essential survival skills from their mother and other group members. They spend their first year in the band, gradually gaining independence.
By the time they reach two years old, most males leave or are expelled from the group to live a solitary life, while females remain within the band and contribute to the group’s social structure. White-nosed coatis typically reach sexual maturity at two to three years old, beginning the cycle again.
This fascinating reproductive process ensures the survival of coati populations while maintaining the balance within their ecosystems.
Foraging Techniques
Tejones are expert foragers who use their strong smell to locate food. They:
- Dig through the soil to find hidden insects.
- Climb trees to pick ripe fruit.
- Use their dexterous paws to grab small prey.
Their adaptability allows them to thrive in environments where food sources change with the seasons.
Habitat and Geographic Distribution
Tejones are highly adaptable mammals and can survive in various habitats across North, Central, and South America.
Where Do Tejones Live?
Their range extends from the southern United States (Texas and Arizona) to Colombia, Ecuador, and Venezuela. They thrive in:
- Tropical rainforests
- Dry forests
- Grasslands and savannas
- Mountainous regions up to 3,000 meters (9,800 feet) above sea level
Interaction with Humans
In some areas, jones has adapted to living near human settlements, especially in Mexico and Central America. Tourists often encounter them in eco-reserves and national parks, where they have become accustomed to human presence.
While they may seem friendly, feeding wild tones can be harmful, disrupting their natural foraging behaviors.
Predators and Survival Strategies
Despite their agility, tejones face threats from natural predators and human activities.
Natural Predators
Tejones are preyed upon by:
- Jaguars and pumas – Large cats are their primary predators in the wild.
- Snakes – Some large snakes, like boas, may prey on juvenile tejones.
- Birds of prey – Hawks and eagles target young tejones.
To defend themselves, jones rely on:
- Speed and agility – They can quickly escape into trees.
- Group defense – Bands of tejones work together to scare off predators.
- Vocal warnings – Alarm calls alert others of nearby threats.
Conservation Status
The white-nosed coat is listed as Least Concern by the International Union for Conservation of Nature (IUCN). However, certain populations are at risk due to:
- Deforestation – Habitat destruction limits their food supply.
- Hunting – In some regions, jones are hunted for their meat or captured for the exotic pet trade.
- Human encroachment – Expanding cities and agriculture reduce their natural habitat.
Conservation Efforts
To protect tones, conservationists emphasize:
- Preserving natural forests to maintain their ecosystems.
- Educational programs to prevent illegal hunting and pet trade.
- National parks and wildlife reserves where tejones can thrive undisturbed.
Their adaptability gives them a strong survival advantage, but continued conservation efforts are crucial for long-term population stability.
Conclusion
The tejón, or white-nosed coati, is an intelligent, social, and resourceful mammal that plays a vital role in its ecosystem. Every aspect of its life, from its group dynamics to its omnivorous diet, showcases its adaptability.
Despite habitat loss and hunting threats, tejones thrive across their native range. Through conservation efforts and responsible eco-tourism, these fascinating creatures can continue to roam the forests and grasslands for generations to come.
Next time you’re in Central or South America, watch for these curious, bushy-tailed foragers—they might be sniffing around for their next meal!
