Data from: Diet and provisioning rate differ predictably between dispersing and philopatric pied flycatchers
Dispersal is an essential process for most animal populations to persist in changing environments. Dispersers are often a non-random sample of the population, and differ consistently from non-dispersers in a suite of correlated phenotypic traits ('dispersal syndromes'). This phenotypic integration is thought to be adaptive. Here, we investigate whether dispersal tendency of individual pied flycatchers (Ficedula hypoleuca) covaries with a set of repeatable behaviors that should confer advantages for surviving and reproducing in novel environments. We specifically focus on the link between dispersal, foraging behavior and aggressiveness because selection on foraging tactics or social behaviors likely differs between individuals staying in familiar or dispersing to novel environments. Using repeated measures of nestling provisioning data of pied flycatcher parents in one year, we tested if immigrants and philopatric individuals (local recruits and experienced breeders) differed in diet specialization, provisioning rates, levels of aggression and reproductive success. Results show that individuals differed consistently in their foraging behavior, with immigrants having a more generalist diet and higher feeding rates than philopatric birds, but not in aggressiveness. More generalist males fledged more young. Our findings suggest that prior local knowledge facilitates diet specialization, and that more generalist diets could be adaptive for immigrants breeding in unknown environments. Aggressiveness was not part of the dispersal syndrome in our population, perhaps because high aggression levels are too costly to maintain in high density populations. Understanding the proximate causes and ultimate consequences of variation in dispersal syndromes requires now experimental manipulations of individual dispersal decisions.
Data from: Mechanical power curve measured in the wake of pied flycatchers indicate modulation of parasite power across flight speeds
How aerodynamic power required for animal flight varies with flight speed determines optimal speeds during foraging and migratory flight. Despite its relevance, aerodynamic power provide an elusive quantity to measure directly in animal flight. Here we determine the aerodynamic power from wake velocity fields, measured using tomographical particle image velocimetry, of pied flycatchers flying freely in a wind tunnel. We find a shallow U-shaped power curve, which is flatter than expected by theory. Based on how the birds vary body angle with speed, we speculate that the shallow curve result from increased body drag coefficient and body frontal area at lower flight speeds. Including modulation of body drag in the model results in a more reasonable fit with data than the traditional model. From the wake structure we also find a single starting vortex generated from the two wings during the downstroke across flight speeds (1-9 m/s). This is accomplished by the arm wings interacting at the beginning of the downstroke, generating a unified starting vortex above the body of the bird. We interpret this as a mechanism resulting in uniform downwash and low induced power, which can help explain the higher aerodynamic performance in birds compared to bats.

Data from: Internal acoustic structuring in pied babbler recruitment cries specifies the form of recruitment
Language is inherently combinatorial, and parallels of this combinatorial capacity are found in nonhuman systems, with animals combining sounds and calls into larger meaningful structures. However, further analogue examples are central in unveiling the diversity, distribution, and evolutionary drivers of combinatoriality. Here, we provide evidence for internal "meaning-refining" acoustic variation within a larger stereotyped signal in pied babblers (Turdoides bicolor). Using acoustic analyses, we demonstrate that males produce 2 long, raucous, "cry-like" structures, both starting with a wind-up segment grading into repetitions of A/single-note or AB/double-note motifs. Behavioral observations indicated that, consistent with similarities in their larger stereotyped structure, both variants function overall in recruiting group members during locomotion, but the internal A or AB substructure specifies the "precise" form of recruitment, from approaching the caller's announced location to following it over longer distances. Playing back cries from a stationary loudspeaker further supported that the 2 variants elicit different responses, with more individuals approaching the loudspeaker in response to single-note compared with double-note cries. Additionally, despite similarities in overall distance travelled, group movement was only directional for single-note, but undefined for double-note cries. We suggest that the overall structure of the 2 cry variants conveys the same general meaning, with embedded variation refining this meaning. These results further illustrate the variability of generative mechanisms outside of human language and lend support to the hypothesis that combinatorial structuring may have emerged in species with limited or fixed vocal repertoires in order to enhance communicative output.
Data from: Meaningful call combinations and compositional processing in the southern pied babbler
Language's expressive power is largely attributable to its compositionality: meaningful words are combined into larger/higher-order structures with derived meaning. Despite its importance, little is known regarding the evolutionary origins and emergence of this syntactic ability. Although previous research has shown a rudimentary capability to combine meaningful calls in primates, because of a scarcity of comparative data, it is unclear to what extent analog forms might also exist outside of primates. Here, we address this ambiguity and provide evidence for rudimentary compositionality in the discrete vocal system of a social passerine, the pied babbler (Turdoides bicolor). Natural observations and predator presentations revealed that babblers produce acoustically distinct alert calls in response to close, low-urgency threats and recruitment calls when recruiting group members during locomotion. On encountering terrestrial predators, both vocalizations are combined into a "mobbing sequence," potentially to recruit group members in a dangerous situation. To investigate whether babblers process the sequence in a compositional way, we conducted systematic experiments, playing back the individual calls in isolation as well as naturally occurring and artificial sequences. Babblers reacted most strongly to mobbing sequence playbacks, showing a greater attentiveness and a quicker approach to the loudspeaker, compared with individual calls or control sequences. We conclude that the sequence constitutes a compositional structure, communicating information on both the context and the requested action. Our work supports previous research suggesting combinatoriality as a viable mechanism to increase communicative output and indicates that the ability to combine and process meaningful vocal structures, a basic syntax, may be more widespread than previously thought.
