Vigilance, Sentinels, and Alarm Calls

Abstract

Vigilance is attentive behavior directed at an animal’s surroundings to detect or monitor perceived dangers. Sentinels are individuals in a social group that scan the surroundings while groupmates are engaged in other activities nearby. Alarm calls are vocalizations given by animals in response to perceived danger from predators.
