The Buenos Aires Zoo was an 45-acre (18 ha) zoo in the Palermo district of Buenos Aires, Argentina. The zoo contained 89 species of mammals, 49 species of reptiles and 175 species of birds, with a total of over 2,500 animals. The institution's goals are to conserve species, produce research and to educate the public. In June 2016 the city formed a bias about the zoo's cruelty. They had to close the 140-year-old zoo and relocate most of the animals to nature reserves, including Temaikèn. The zoo property will be converted into an ecopark.
