Maned wolves (Chrysocyon brachyurus) are usually very quiet animals, but on occasion they will make a noise called a "roar-bark." It begins at 0:50.
That is quite an interesting sound, isn't it! The roar-bark is one of only three vocalizations they make, the other two being a grown and high-pitched whine. Maned wolves, also sometimes called "stilted foxes," are fascinating animals. The "wolf" and "fox" descriptors are misnomers because the maned wolf is actually an more distant offshoot of the Canidae family and not closely related to either wolves or foxes. Nearly a meter in height, they are omnivores and their diet consists mainly of a fruit called "wolf apples" ( ). They also feed on small animals and are known to occasionally take free-range chickens. They are native to Brazil, though their territory once reached into several neighboring countries. In captivity, they do best in opposite-sex pairings. Young are born very dark and will lighten with age. They are Near Threatened on the IUCN Red List.
