Individual, age and sex-specific information is contained in yellow-bellied marmot alarm calls
Individuals produce distinctive vocalizations that may contain considerable potential information about a signaller. Simply finding significant covariation between call structure and some individual attribute does not itself mean that there has been selection on callers to produce individually distinctive calls, nor on receivers to discriminate between them. Moreover, acoustic variation may deg...
متن کاملYellow-bellied marmot and golden-mantled ground squirrel responses to heterospecific alarm calls
When two species have predators in common, animals might be able to obtain important information about predation risk from the alarm calls produced by the other species. The behavioural responses of adult yellow-bellied marmots, Marmota flaviventris, and golden-mantled ground squirrels, Spermophilus lateralis, to conspecific and heterospecific alarm calls were studied to determine whether inter...
متن کاملYellow-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 کاملAlarm 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, ...
متن کاملHornbills can distinguish between primate alarm calls.
Some mammals distinguish between and respond appropriately to the alarm calls of other mammal and bird species. However, the ability of birds to distinguish between mammal alarm calls has not been investigated. Diana monkeys (Cercopithecus diana) produce different alarm calls to two predators: crowned eagles (Stephanoaetus coronatus) and leopards (Panthera pardus). Yellow-casqued hornbills (Cer...
