Facts

  • Males and females are sexually dimorphic; adult males are black, adult females and juveniles are a golden tan color
  • Howler monkeys are the loudest primates in the Americas
  • Males do most of the howling. They can be heard 1.8 miles away in the forest, and 3 miles away over water.
  • The hyoid bone in their throat is modified and forms a bony box called a corniculum. The corniculum is an egg-shaped pouch that acts as an amplifying chamber, enabling these monkeys to out- howl all other land animals.
  • Loud howls, grunts, roars and barks they use to defend territory
  • They are arboreal, diurnal, and have a prehensile tail.
  • Troop sizes range from 3 to 19. Troops commonly have 1 to 3 adult males and 2 to 7 adult females.
