The production of and responses to alarm calls by adult ground-dwelling squirrels has been widely documented, yet the development of alarm-call behaviours has not been systematically addressed. The responses of free-living Belding's ground squirrels, Spermophilus beldingi, to playbacks of conspecific (three alarm calls and juvenile squeals) and heterospecific (wren song) vocalizations were observed from natal emergence until the age of dispersal. Discrimination of thefive auditory stimuli was… Expand
Development of alarm-call responses in Belding's ground squirrels: the role of dams
TLDR
Two processes of influence, direct and indirect, are proposed to describe the effect of adult behaviours on juvenile development as experiences with adult conspecifics can influence the ontogeny of species-typical behaviours in naive young of many species. Expand
Plasticity of Alarm‐call Response Development in Belding’s Ground Squirrels (Spermophilus beldingi, Sciuridae)
TLDR
Responses of free-living juveniles appeared to be more discriminating than responses of captive juveniles, particularly following playbacks of calls associated with less immediate threats, which suggests that early rearing history has an enduring effect on response repertoires, which may be adaptive if animals continue to inhabit the predator environment in which they developed. Expand
How Rearing History Affects Alarm‐call Responses of Belding’s Ground Squirrels (Spermophilus beldingi, Sciuridae)
TLDR
Sensitivity to early rearing environments may be adaptive for young ground squirrels if it facilitates the development of antipredator behaviour patterns that are appropriate for the local predator environment (e.g openness of habitat, frequency of predators, availability of refuges). Expand
Adaptive differences in response to two types of parental alarm call in altricial nestlings
TLDR
It is found that scrubwren nestlings can distinguish between different types of alarm calls and react more strongly to calls warning of a predator posing greater danger, appropriate to the nestling stage of development. Expand
Age Differences in the Response of California Ground Squirrels (Spermophilus beecheyi) to Conspecific Alarm Calls
Juvenile California ground squirrel responses to adult alarm calls and juvenile alarm calling may be modified during development to achieve adult form. Adult conspecific chatter and whistle alarmExpand
Early auditory experience and the ontogeny of alarm-call discrimination in Belding's ground squirrels (Spermophilus beldingi).
TLDR
Results suggest that before natal emergence, young can discriminate between 2 classes of alarm calls but they may not discriminate these calls from control stimuli, and early discrimination may facilitate the rapid development of post-emergent behavioral alarm-call responses. Expand
The More the Scarier: Adult Richardson’s Ground Squirrels (Spermophilus richardsonii) Assess Response Urgency Via the Number of Alarm Signallers
TLDR
The present results suggest a developmental shift in response-urgency perception in Richardson's ground squirrels, with adult RGS selectively extract information regarding response urgency via discrimination of the number of callers, ignoring less reliable information encoded in the rate of repetitive calls issued by inexperienced juvenile signallers. Expand
Ontogeny of alarm call responses in meerkats, Suricata suricatta: the roles of age, sex and nearby conspecifics
TLDR
It is concluded that young may need experience during early development to associate an alarm call correctly with the type of threat and appropriate response and older group members may also serve as indirect models, perhaps helping young to form this association. Expand

From nestling calls to fledgling silence: adaptive timing of change in response to aerial alarm calls
TLDR
Supporting the authors' prediction, recently fledged white-browed scrubwrens, Sericornis frontalis, fell silent immediately after playback of their parents' aerial alarm call, whereas nestlings continued to calling despite hearing the playback, suggesting that Young scrub wrens are exquisitely adapted to the changing risks faced during development.

Different Functions of "Alarm" Calling for Different Time Scales: a Preliminary Report On Ground Squirrels
TLDR
It is proposed that predator-prey episodes may be understandable from an "epigenetic" perspective; that is, the first alarm calls during an encounter should shift squirrels from an unwarned to a warned status; subsequent calling must then function in some other way than as a warning. Expand

Abstract Eastern chipmunks, Tamias striatus , were more likely to flee the area and assume a motionless alert posture in response to playback of conspecific alarm calls than they were in response toExpand
Behavioral responses to species‐specific warning calls in infant squirrel monkeys reared in social isolation
TLDR
Six infant squirrel monkeys were reared in social isolation and responded differentially to playbacks of two species‐specific alarm calls, concluding that the perception of both alarm calls is innate. Expand
Selective resistance to approach: a precursor to fear responses to an alarm call in great tit nestlings Parus major.
The reactions of 10-day-old great tit nestlings to 3 auditory stimuli were studied. The stimuli, presented on a series of feeding occasions, were (1) the species' “seeet” alarm call, (2) a songExpand
Vocalizations of Belding's ground squirrels (Spermophilus beldingi)
TLDR
Sonagrams of trills occurring in agonistic contexts suggest that a third general category of trill may exist, but agonistic trills were more variable than either anti-predator or post-copulatory trills. Expand
Behaviour in a population of Columbian ground squirrels, Spermophilus columbianus columbianus
TLDR
The behaviour of this population of Columbian ground squirrels was similar to that observed in other populations of the same and other sciurids, but most differences cannot be explained without ecological investigation of the other populations. Expand
PARENT-YOUNG VOCAL COMMUNICATION IN EARED GREBES
TLDR
Although young chicks respond to the food and alarm calls from any adult of their species, playback experiments using the advertising calls of adults suggest that older grebe chicks can learn to individually identify their parents by the time they begin swimming on their own. Expand
Demography of Belding's ground squirrels
TLDR
Sexual asymmetries in the demographic characteristics of S. beldingi appear to result from the animals' polygynous breeding system. Expand
