Black 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.
