Black Howler Monkey

Only the adult males of this species are black; the females range from golden brown to olive brown, and infants are born blonde. They are named for their vocalizations, 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.
