For the Björk single, see Alarm Call.

Concerning animals, an alarm call refers to various vocalizations that they emit in response to danger. Many primates and birds have elaborate alarm calls for warning other animals of the same species about approaching predators. For example, the blackbird’s characteristic alarm call is a familiar sound in many gardens. Different calls may be used for predators on the ground or from the air. Often, the animals can tell which member of the group is making the call, so that they can disregard those of little reliability.
