“…Thus, the feedback between social information use and production produced substantially lower overall aggression than would be predicted by simply studying pairs of males without eavesdroppers (e.g., in our no eavesdropper treatment), or investigating male eavesdropping without also considering its effect on social information production (e.g., in our no social information treatment). Our results are therefore consistent with previous work that shows obtaining social information about the fighting ability of an opponent may allow individuals to avoid prolonged or escalated encounters (Beltrão et al, 2023;Magnhagen, 2006;Tibbetts et al, 2020); notably, these previous results were obtained without accounting for any influence of the eavesdropper presence on the social information that was produced.…”

Social information use and production occur simultaneously during social learning events; however, these two processes are often studied independently. We propose that social information use and production represent a feedback loop: eavesdroppers influence the behaviors of those being observed, which then alters the eavesdroppers' social decisions. Here, we used Drosophila melanogaster to investigate the relationship between social information use and production in an aggressive context. We quantified aggressive behavior between two males being observed by either a male, female, or no one. We then measured variation in social information use by allowing the eavesdroppers to interact directly with the observed males and compared their behavior to individuals who did not observe the aggressive encounter. Male eavesdroppers caused the observed males to decrease their aggressive behaviors, thus altering their social information production. Male eavesdroppers were then less likely to attack observed contest winners than males without social information. Female eavesdroppers did not elicit any change in the aggression of the two males, and female eavesdroppers did not use social information to inform their mating decisions. Overall, we found support for the feedback loop in males, but not females: information was exchanged bi-directionally during eavesdropping events, resulting in the modification of behavior by all parties.

“…Playback experiments in a captive group of monk parakeets indicate that sharing space may beneficial for predator avoidance (Estien et al, 2020). Additionally, by sharing space with strangers monk parakeets may assess individual identity through unique vocal signatures (Smeele et al, 2023;Smith-Vidaurre et al, 2020) or conspecific's fighting ability (Beltrão et al, 2023;Hobson & DeDeo, 2015;van der Marel et al, 2023b) while minimizing the risk of receiving aggression and maximizing the amount of time to flee or prepare for defense if rejected (Narizano & Carter, 2020;Silk et al, 1996).…”

Familiarity with social partners influences affiliative interactions but not spatial associations

To successfully navigate complex social environments, animals must manage their relationships with familiar group members and strangers introduced via fission-fusion or demographic processes by deciding who, how often, and when to interact. However, it is not clear how animals balance the risks and benefits of interacting with familiar and stranger conspecifics. We studied whether familiarity among group members affect the patterning and timing of spatial associations and affiliative interactions in a captive group of 22 monk parakeets (Myiopsitta monachus) captured from four geographically distinct sites. We tested whether familiar and stranger dyads differed in the presence, strength, and timing of spatial and affiliative relationships. We found that general patterns of spatial proximity between birds were unaffected by capture site. In contrast, all affiliative interactions, like allopreening and beak touching, occurred significantly more often among familiar birds compared to stranger dyads. These affiliative interaction networks were also more densely connected, but relationships were not always stronger among familiar birds compared to strangers. Familiar and stranger birds did not differ in the timing of initiation of spatial proximity, while most affiliative interactions among strangers occurred significantly later in the experiment compared to familiar birds. In contrast, we found that the familiar and stranger spatial networks were equally well-connected, but associations were stronger among familiar birds. Our results show that monk parakeets discriminate between familiar and unfamiliar birds and suggest that birds use their previous experiences to make affiliative social decisions. By investigating the effect of familiarity on spatial and affiliative interactions we gain a better understanding of how individuals manage the costs and benefits of interacting with unfamiliar individuals.
