Vervet monkeys alarmed by crowned eagle

A male adult vervet monkey responds to the presence of a calling crowned eagle that is perched in a nearby tree. The vervet gives an alarm call while watching the eagle intently. After the crowned eagle flies away a monkey takes up a sentry position to keep watch from a tree while two juvenile monkeys watch and forage from dense bush below.
