The newborn black howler monkey at Cleveland Metroparks Zoo seems so small and so quiet right now. But once the pint-sized primate grows up, it’ll be among the loudest animals on the planet.

Second in volume only to the blue whale, the black howler monkey is the loudest animal on earth, emitting yells that can be heard up to two miles away. The Zoo’s newest howler monkey was born on May 28 to mother Springer and father Oz, who had their first offspring together about a year ago.

Their baby, whose sex has yet to be determined, clings to its mother 24 hours a day and likely will do so for a few more months before venturing out alone. It has blondish brown hair matching Springer’s, and will stay that way if it’s a female or turn dark black over time if it’s a male.

Black howler monkeys are endangered in their native Latin American rainforests because of hunting and habitat destruction. Their loud howling is most prevalent early in the morning and late at night, and troops in the wild use it to gauge their distance from other howler monkeys they might be competing with for food or territory.

While only able to squeak so far, the infant howler monkey at the Zoo is doing well and is on display in the Primate, Cat & Aquatics Building daily.
