“…Indeed, in colonially breeding species, like roseate terns, parents should discriminate their mobile offspring from others' during both pre‐ and postfledging periods to avoid costs of misdirected parental care (Aubin & Jouventin, ; Levréro et al, ). In such a situation, offspring cheating may be rare because it is unlikely that a nonparent will be fooled by a dishonest HY; thus, there may be few benefits to gain from cheating (Rich & Zollman, ; Zollman et al, ). Although we found little evidence of adult aggression toward offspring in our system, it is possible that aggressive interactions between nonparents and cheating offspring may mediate the honesty of begging at parents versus nonparents (Davies, ); however, we were unable to evaluate this hypothesis with our data.…”

“…Alternatively, an evolutionarily stable strategy may still be achieved in the absence of high costs if there is little to be gained from displaying the behavior dishonestly (Royle, Hartley, & Parker, ). For example, begging may not be a particularly costly behavior for fledged chicks, but this behavior may remain honest due to a relatively low payoff of cheating (e.g., begging at unrelated adults or soliciting more care than needed may not result in feeding; Zollman, Bergstrom, & Huttegger, , Rich & Zollman, ).…”

Honest signaling mechanisms can function to appropriate care to hungry offspring and avoid misdirected care of unrelated offspring. Begging, the behavior by which offspring solicit food and parental care, may be an honest signaling mechanism for need, as well as association of parents and offspring. Roseate terns ( Sterna dougallii ) exhibit prolonged parental care during the postbreeding staging period, offering an ideal system in which to study begging as an honest signaling mechanism. We conducted focal sampling during two premigratory staging seasons (2014 and 2015) at Cape Cod National Seashore, Massachusetts, USA to determine whether postfledging tern begging behavior was an honest signal for need and parent–offspring association. Based on honest signaling theory, we expected begging behavior to be highest during times of high perceived need, and we expected to see a decrease in begging behavior as young terns became increasingly independent of the care‐giving parent. Also, we predicted that young terns would be more likely to beg at parents than nonparents. We found that young roseate terns begged at their parents more often than nonparents; however, they did not always beg at parents. Model predictions of begging probability showed a linear relationship between begging and time of day and date of season, such that begging increased with time of day and decreased with date of season, respectively. Our results provide evidence for honest parent–offspring interactions and are inconsistent with parent–offspring conflict theory but suggest that begging may play a complex role in postfledging parent–offspring interactions.

“…For example, many religious markers, such as head coverings or adornments, are not intrinsically linked to their bearer's character, but are, however, policed by others. Such arbitrary links could be sustained when signals are at least partially verifiable: that is, receivers can in the long term evaluate when signals are dishonest . Establishing the conditions under which signal costs should, or should not, be tightly related to signal content is an important area for further study.…”

Humans frequently perform extravagant and seemingly costly behaviors, such as widely sharing hunted resources, erecting conspicuous monumental structures, and performing dramatic acts of religious devotion. Evolutionary anthropologists and archeologists have used signaling theory to explain the function of such displays, drawing inspiration from behavioral ecology, economics, and the social sciences. While signaling theory is broadly aimed at explaining honest communication, it has come to be strongly associated with the handicap principle, which proposes that such costly extravagance is in fact an adaptation for signal reliability. Most empirical studies of signaling theory have focused on obviously costly acts, and consequently anthropologists have likely overlooked a wide range of signals that also promote reliable communication. Here, we build on recent developments in signaling theory and animal communication, developing an updated framework that highlights the diversity of signal contents, costs, contexts, and reliability mechanisms present within human signaling systems. By broadening the perspective of signaling theory in human systems, we strive to identify promising areas for further empirical and theoretical work.

“…Repeated interactions with individuals that can be individually recognized may be important in allowing receivers to learn about the behaviour of specific signallers [32]. Such contexts also allow receivers to attend more to specific signallers that have demonstrated signal reliability, and provide a mechanism that can ensure signal honesty [33]. Such effects have been studied in relation to alarm calls, where theoretical models demonstrate fitness benefits that accrue to individuals discriminating between specific signallers [34], and where empirical data suggests that receivers do indeed preferentially attend to the calls of reliable signallers (e.g.…”

The role of familiarity in signaller–receiver interactions

In animal communication, individuals of species exhibiting individual recognition of conspecifics with whom they have repeated interactions, receive signals not only from unfamiliar conspecifics, but also from individuals with whom they have prior experience. Empirical evidence suggests that familiarity with a specific signaller aids receivers in interpreting that signaller's signals, but there has been little theoretical work on this effect. Here, we develop a Bayesian decision-making model and apply it to the well-studied systems of primate ovulation signals. We compare the siring probability of learner males versus non-learner males, based on variation in their assessment of the best time to mate and mate-guard females. We compare males of different dominance ranks, and vary the number of females, and their cycle synchrony. We find strong fitness advantages for learners, which manifest very quickly. Receivers do not have to see the full range of a signaller's signals in order to start gaining familiarity benefits. Reproductive asynchrony and increasing the number of females both enhance learning advantages. We provide theoretical evidence for a strong advantage to specific learning of a signaller's range of signals in signalling systems. Our results have broad implications, not only for understanding communication, but in elucidating additional fitness benefits to group-living, the evolution of individual recognition, and other characteristics of animal behavioural biology.rsif.royalsocietypublishing.org J.
