More than 220 bird species have been registered here, among others significant
populations of jacutinga (Pipile jacutinga) a bird that lives mainly from the fruit of the
juçara palm tree (Euterpe edulis).
Carlos Botelho also protects the endemic spider monkey
(Brachyteles arachnoides) or muriqui, the largest primate in the Americas.
From a total population of 1.200 species living in Brazil,
approximately 600 to 800 can be found within the border of the park. This and other
endangered species as the Jaguar (Panthera Onça) are evidence of the high degree of conservation of this conservation unit.
