Adults weigh between 4-7kg, depending on sex. They are predominantly black with lighter coloring on their sides and mid-riff. Males have a very distinctive white scrotum which enables easy identification of the species! They have a fur-less face and a patch near the tip of their prehensile tail that is also fur-less and aids their movement through the trees.

At Alturas: Roo is our most recent sanctuary resident and was attacked by capuchins when she was a baby, resulting in her leg having to be amputated. You can see her on one of our four tours a day from Tuesday-Sunday. Howler monkeys are one of the most common primate species we receive at Alturas, and can be brought to us for a range of reasons from attacks by other monkeys to road traffic accidents.
