Usually, howler monkeys have a single dominant male, with multiple adult females and babies in smaller groups. [13] In larger groups, the howler monkeys' group composition can vary. [ 13 ] In a 2009 study by Lucas M. Aguiar, Gabriela Ludwig, and Fernando C. Passos, in the Upper Paraná River of southern Brazil, the black and gold howler groups ...
The mantled howler's appearance is similar to other howler monkeys of the genus Alouatta except for coloration.
