Vocal Kin recognition in Kin neighborhoods of western bluebirds
Behavioral Ecology, 2013Co-Authors: Çağlar Akçay, Rose J. Swift, Veronica A. Reed, Janis L. DickinsonAbstract:In most cooperatively breeding birds, individuals direct helping behavior to close relatives. Western bluebirds live in family groups in winter and show a high degree of male philopatry. Sons disperse locally forming Kin neighborhoods and occasionally help at their parents’ or brothers’ nests. Although the pattern of Kin-directed helping is well established in birds, the mechanism of recognition is known in only a few cases. Here, we report on an experiment with western bluebirds (Sialia mexicana) that investigates the role of vocalizations in Kin recognition, a species that even when breeding on its own often maintains lifelong connections with Kin. We presented western bluebirds with songs recorded from equidistant Kin and nonKin living on other territories, conducting playback near their nests on 2 consecutive days. We found that male western bluebirds responded more aggressively to playback of nonKin song compared with Kin song. These results suggest that vocal signatures serve as a Kin recognition cue in western bluebirds. We discuss these results within the context of other systems in which vocal Kin recognition has been demonstrated and discuss the potential for further research to examine signal development and to distinguish Kin signatures from individual signatures, which can also be used to recognize Kin.

Sex differences in Kin bias at maturation: Male rhesus macaques prefer paternal Kin prior to natal dispersal
American journal of primatology, 2015Co-Authors: Anja Widdig, Doreen Langos, Lars KulikAbstract:Dispersal and mating patterns are known to affect the availability of both maternal and paternal Kin within social groups, with important effects on the evolution of sociality. It is generally assumed that the philopatric sex forms stronger social bonds than the dispersing sex, possibly as a result of reduced Kin availability for the dispersing sex after departure. However, few primate studies have directly compared whether sex differences in association patterns, particular with Kin, are already present prior to dispersal when Kin availability should be the same for both sexes. Here, we compared affiliative and aggressive interactions in a female philopatric species, the rhesus macaque (Macaca mulatta), to test whether sex differences in Kin bias already occur around the age of maturation, when both sexes still live together with Kin in their natal group. Our data confirmed that Kin availability was the same for both sexes prior to male dispersal. Similar Kin availability was partially reflected by comparable association patterns, as both females and males preferentially interacted with maternal Kin. However, females had stronger affiliative bonds with maternal Kin than males of the same age, indicating that Kin associations not only depended upon Kin availability, but were also sex-specific. Similarly, males were significantly more likely to affiliate with paternal Kin than non-Kin, as compared to females, suggesting that males discriminated paternal Kin from non-Kin earlier in life than females. Males might have a stronger need than females to affiliate with paternal Kin due to a reduced integration in the matrilineal family prior to dispersal and the high availability of paternally related age-peers, with whom males could potentially migrate. Females, in contrast, form stronger affiliations with maternal Kin, which may enhance their offspring's survival. More comparative studies are needed to understand the impact of different dispersal regimes on patterns of Kin associations. Am. J. Primatol. © 2015 Wiley Periodicals, Inc.

Male rhesus macaques use vocalizations to distinguish female maternal, but not paternal, Kin from non-Kin
Behavioral Ecology and Sociobiology, 2015Co-Authors: Dana Pfefferle, Angelina V. Ruiz-lambides, Anja WiddigAbstract:Recognizing close Kin and adjusting one's behavior accordingly (i.e., favor Kin in social interactions, but avoid mating with them) would be an important skill that can increase an animals' inclusive fitness. Previous studies showed that philopatric female rhesus macaques (Macaca mulatta) bias their social behavior toward maternal and paternal Kin. Benefits gained from selecting Kin should, however, not only apply to the philopatric sex, for which the enduring spatial proximity facilitates Kin discrimination. Given that dispersal is costly, the dispersing sex may benefit from migrating together with their Kin or into groups containing Kin. In male rhesus macaques, natal migrants bias their spatial proximity toward familiar male Kin rather than familiar non-Kin. Here, we set up playback experiments to test if males use the acoustic modality to discriminate familiar female Kin from non-Kin in a non-sexual context. Males responded differently to the presentation of "coo" calls of related and unrelated females, with their reaction depending on the interaction between Kin-line (maternal vs paternal Kin) and degree of relatedness (r = 0.5, 0.25). Specifically, males were more likely to respond to close Kin compared to more distant Kin or unrelated females, with this effect being significant in the maternal, but not paternal Kin-line. The present study adds to our knowledge of Kin recognition abilities of the dispersing sex, suggesting that male rhesus macaques are also able to identify Kin using the acoustic modality. We discuss that the probability of response might be affected by the potential benefit of the social partner.
