A call-and-response system facilitates group cohesion among disc-winged bats
TLDR
It is argued that differences in how individuals respond to calls from group and nongroup members may be partly attributed to the costs associated with flight and the potential benefits of recruiting roost mates.

Identity information in bonobo vocal communication : from sender to receiver
Identity information is vital for highly social species as it facilitates individual recognition and allows for differentiation between social partners in many contexts, such as dominance

Greater spear-nosed bats give group-distinctive calls
TLDR
Testing two hypotheses about how screech calls may be structured to convey caller identity reveal that group calls are highly distinctive.
Individuality in the contact calls of cooperatively breeding long-tailed tits (Aegithalos caudatus)
TLDR
This is the first quantitative description of potential recognition cues in a cooperatively breeding bird in which vocal discrimination is known to occur and it is hypothesised that long-tailed tits are able to discriminate between the calls of conspecifics based on these parameters.
Unusually extensive networks of vocal recognition in African elephants
TLDR
Female elephants appear to have unusually extensive networks of vocal recognition, which may prove to be typical of long-lived species that have both fluid social systems and the means for long-distance vocal communication.
The influence of social affiliation on individual vocal signatures of northern resident killer whales (Orcinus orca)
TLDR
Results show that frequency contours of stereotyped calls differ among the individuals that are constantly associated with each other and use group-specific vocalizations, though across-group differences were substantially more pronounced.
Long-distance communication of acoustic cues to social identity in African elephants
Abstract Research on long-distance vocal communication in mammals has tended to focus on the maximum distances over which a vocal signal might be physically detectable. For example, because elephants
Vocal recognition of individuals and kin in free-ranging rhesus monkeys
TLDR
F Females' responses to playbacks suggested the additional possibility for categorical recognition of matrilineal kinship, or its correlates, and results indicate an ability for vocal recognition of both individuals and kin.
Sex-specific responses to vocal convergence and divergence of contact calls in orange-fronted conures (Aratinga canicularis)
TLDR
It is demonstrated that orange-fronted conures can discriminate between male and female contact calls and that subtle changes in contact call structure during interactions have signal function.
Wild Chimpanzees Produce Group‐Specific Calls: a Case for Vocal Learning?
TLDR
It is suggested that chimpanzees may actively modify pant hoots to be different from their neighbours, providing support for the vocal learning hypothesis.
