Alarm Calls
Animals commonly vocalize when threatened by a predator. These signals, usually termed alarm calls (from old Italian all arme ‘to arms’ on the approach of an enemy), have continued to bewilder and fascinate for a number of reasons, the first of which is mainly practical. In animal research, it is often difficult to break down the continuous behavioral stream into discrete and meaningful units, ...

15 صفحه اولYellow-bellied marmots discriminate between the alarm calls of individuals and are more responsive to calls from juveniles
Unlike individually distinctive territorial calls, contact calls, or calls that aid in the recognition of young by their parents, the function or functions of individually distinctive alarm calls (vocalizations produced in response to predators) is not immediately apparent. Yellow-bellied marmots, Marmota flaviventris, grounddwelling sciurid rodents, produce individually distinctive alarm calls...
متن کاملWild Birds Learn to Eavesdrop on Heterospecific Alarm Calls
Many vertebrates gain critical information about danger by eavesdropping on other species' alarm calls [1], providing an excellent context in which to study information flow among species in animal communities [2-4]. A fundamental but unresolved question is how individuals recognize other species' alarm calls. Although individuals respond to heterospecific calls that are acoustically similar to...
متن کاملEastern chipmunks increase their perception of predation risk in response to titmouse alarm calls
Vocally signaling a predator’s presence through alarm calls creates public information regarding risk in the environment. If having this information confers an advantage, eavesdropping behavior, the use of information in signals by individuals other than the primary target, is expected to evolve. Thus, eavesdropping for information on predation risk to avoid predators may be common. We describe...
