The National Zoo has a new addition at the Small Mammal House.

A black howler monkey was born March 22 to first-time parents Chula, the mom, and Pele, the dad.

Zookeepers are watching the new family from a distance but report that the baby seems bright, alert and active. Scientists have not gotten close enough to tell if the new monkey is a boy or a girl.

Howler monkeys get their name because they have a unique voice box that allows the rumbling, growling sound they make to travel up to three miles even through dense forest.

Visitors to the zoo can see the howler monkey family in the Small Mammal House. To see more pictures of the zoo’s new addition, as well as other new zoo babies from around the world, go to
