Black-and-Gold Howler Monkey

Named for their vocalizations, howler monkeys are heard most often around sunrise. This “dawn chorus” sounds much more like a low roaring than howling, and it announces the howlers’ position as a means to avoiding conflict with other groups. Their call can be heard more than 3 miles away.

  • We provide support for planting trees for wildlife like Howler monkeys in Colombia.

Where to See Them Inside the Zoo

Walking under the “lodge” deck in South America’s Pantanal, the first animals guests will encounter are a family of howler monkeys that occasionally burst into a cacophony of the loud vocalizations, which give them their distinctive name. The dimorphic monkeys – males are black, females are brown – rarely come down from the trees they live in and use their strong prehensile tail as a fifth limb, allowing them greater versatility when climbing.
