We are deeply saddened to say goodbye to Storm, our red-capped mangabey, who lived to be 28 years old—among the oldest of his species in the world.
They are very noisy birds and often gabble to each other like geese while feeding. The most important role of vocalization is to keep the flock together. They also perform honking, grunting and growling as adults, and chicks start cheeping several hours before they hatch.
Enjoy more of the Zoo you love with free admission and parking, exclusive hours and events, and so much more. Plus, a portion of every membership goes towards saving wildlife. Membership pays for itself in just two visits!
