Vocal individuality cues in the African penguin (Spheniscus demersus): a source-filter theory approach

It is suggested that studying the anatomical constraints that influence nesting penguin vocalisations from a source-filter perspective, can lead to a much better understanding of the acoustic cues of individuality contained in their calls.

Vervet monkey alarm calls: Setting the historical context

Overall, the vervet alarm papers have stimulated great interest in the cognitive complexity of animal signals, but, strikingly, it has been difficult to find clear evidence of predator specific alarms in more than a small number of other species.

Experimental predator intrusions in a cooperative breeder reveal threat-dependent task partitioning

It is shown how breeders and helpers of the cooperatively breeding cichlid Neolamprologus savoryi partition predator defense depending on intruder type and the presence of dependent young, and that in a highly social fish different group members exhibit fine-tuned behavioral responses in dependence of ecological and reproductive parameter variation.

Vocal individuality of Holstein-Friesian cattle is maintained across putatively positive and negative farming contexts

This study shows that cattle vocal individuality of high-frequency calls is stable across different emotionally loaded farming contexts, with all vocal parameters except subharmonics responsible for this individual distinctiveness.

Feature Representations for Automatic Meerkat Vocalization Classification

Investigation of feature representations for automatic meerkat vocalization analysis reveals that feature extraction methods developed for human speech processing can be effectively employed for automatic meerkat call analysis.

What makes an Australian sea lion (Neophoca cinerea) male's bark threatening?

2 key acoustic features that Australian sea lion (Neophoca cinerea) males most likely rely on to assess the threat level posed by potential rivals are investigated, by manipulating bark rhythmicity and spectral characteristics.

Flexible alarm calling in meerkats: the role of the social environment and predation urgency

The results indicate that variation in alarm call production depends on whom the call is addressed to and also on the motivational state of the caller, suggesting that neglecting to integrate internal and external factors when elucidating mechanisms underlying vocal production can potentially lead to misguided, parsimonious conclusions regarding vocal flexibility in animals.

All clear? Meerkats attend to contextual information in close calls to coordinate vigilance

This is the first evidence for socially foraging animals using the information encoded within calls, the main adaptive function of which is unrelated to immediate predator encounters, to coordinate their vigilance behaviour, and new insights are provided into the potential cognitive mechanisms underlying anti-predator behaviour.

Monkey responses to three different alarm calls: evidence of predator classification and semantic communication.

Recordings of the alarms played back when predators were absent caused Vervet monkeys to run into trees for leopard alarms, look up for eagle alarms, and look down for snake alarms.

Collective Vigilance in the Greater Kudu: Towards a Better Understanding of Synchronization Patterns

Investigating individual and collective vigilance in a natural population of greater kudu, a gregarious ruminant living under high predation risk, shows that the proportion of time during which at least one individual was vigilant increased with group size, whereas individual investment in vigilance decreased.

Social monitoring via close calls in meerkats

It is argued that social monitoring based on non-agonistic cues is probably a common mechanism in group-living species that allows the adjustment of behaviour depending on variation in relationships.
