The Bugio (Alouatta guariba), also known as Guariba, Barbado, Roncador or Macaco-uivador is among the largest Neotropical primates, with length of 30 to 75 centimeters. The Bugio is the species of monkey that inhabits the Atlantic Forest, from southern Bahia to South Brazil. Their coat colors range from red, red brown, brown and dark brown. The males are red-orange and the females and young are dark brown. The Bugio is recognized for his loud cry to communicate, as if each individual was saying, “I’m here.” It is usually heard when other groups are seen approaching or invading the territory of the other individual.
