Capybaras graze on a variety of grasses, aquatic plants, and even fruits and bark from trees. Their large, continuously growing incisors are perfectly suited for their diet, allowing them to efficiently consume and break down plant matter.
Behavior
Social structure of the lesser capybara
Lesser capybaras are highly social creatures, often inhabiting their habitats in small groups called “troops” or “harems.” These groups are typically led by a dominant male who ensures the safety and well-being of the troop. Lesser capybaras use vocalizations and various body postures to communicate and establish social hierarchies within their groups. They also have a remarkable ability to navigate steep terrain, making them well-suited for their mountainous habitats.
Social structure of the capybara
Capybaras are known for their incredibly social nature and form large social groups called “herds” or “capybara communities.” These herds can consist of several individuals, ranging from a few to over 100 capybaras. Within these herds, complex social hierarchies are established, with dominant males and females leading the group. Capybaras communicate through a variety of vocalizations, scent markings, and physical displays to maintain social cohesion and ensure group dynamics.
Reproduction
Breeding behavior of the lesser capybara
During the breeding season, the dominant male in a troop of lesser capybaras will mate with multiple females. After a gestation period of approximately 140 to 150 days, the female will give birth to a litter of usually two or three young, known as pups. The pups are born fully furred and with eyes open, ready to explore their surroundings. They are nurtured and protected by the mother and the other members of the troop until they are independent enough to fend for themselves.
Breeding behavior of the capybara
Capybaras also have a similar breeding pattern, but due to their larger herds, the breeding dynamics are more complex. Dominant males will mate with multiple females, resulting in the birth of litters ranging from one to eight pups. The pups are precocial, meaning they are relatively mature and independent at birth compared to many other mammals. They will nurse and receive care from the mother and other herd members until they are capable of accompanying the herd on various activities.
