Core Event
On July 30, a pair of capybaras—the world’s largest rodents—wandered into the reception area of the Legislative Assembly of Mato Grosso in Cuiabá, Brazil. Security turnstiles halted their progress, and building staff guided the animals back toward the nearby park. The incursion caused no injuries or damage to the facility, according to reports from the Associated Press and United Press International.
Background & Context
Capybaras are native to South America, semi-aquatic rodents that thrive near fresh water, rivers, lakes, and wetlands. Weighing up to 80 kg (175 lb), they are highly social and often seen grazing on grass, corn, beans, and carrots. The assembly building sits adjacent to Parque das Águas, which hosts a resident capybara population. Staff note that a fountain in front of the building provides a regular water source, prompting the animals to cross the street and linger near the legislature, especially at dusk.
