Complex behavioral sequences such as courtship displays are often multimodal, and coordination between modalities is critically important. In learned variable behavioural songs, individual variability may also extend to multimodal the associations modalities. However, in complex distinct behaviours remains underexplored. Here, we report that budgerigars, which continuously learn modify their warble exhibit body movements song notes during courtship. Some unique individuals, others universal across individuals. Additionally, some individuals more than others. We find birds warbling absence of emit all with broadly similar odds ratios. Our data suggest a hierarchy associations, individual-specific common songs. propose these be learnt modified through social interactions, resulting variability.

Many building blocks of human language can be found within the vocal communication systems other species, most notably songbirds. One prominent these is syntax. While studies syntax are abundant, a lack consensus on definition in non‐human animal has led to much debate. Consistent and deliberate use terminology needed facilitate understanding across disciplines. In addition, new may better describe syntactic structure signals that devoid semantic associations, such as birdsong. Here, we propose two terms types commonly birdsong: sequential dialectical Sequential defined rules govern patterns sound without regard meaning. Dialectic distinct among different populations or groups with behavioral significance for those groups. Taken together, type seen ornamental signals,

Decision-making in animals often involves choosing actions while navigating the environment, a process markedly different from static decision paradigms commonly studied laboratory settings. Even decision-making assays which can freely locomote, outcomes are interpreted as happening at single points space and moments time, simplification that potentially glosses over important spatiotemporal dynamics. We investigated locomotor

Abstract Urbanization is causing fundamental changes to natural environments, effecting rapid and substantial adaptive phenotypic change in wild populations. While a large body of work has investigated how urbanization may shape interspecific variation behavioral traits, such as via urban environmental filtering, no study yet quantitatively assessed global patterns urban-associated intraspecific variation. Here, we conducted phylogenetic meta-analysis assess differences populations birds, mammals, amphibians, reptiles, insects. We focused on four commonly measured behaviors (boldness, aggression, activity, exploration) extracted paired urban-nonurban effect size estimates for means variances ( k = 278), repeatability 13), correlations 14) from 80 studies. found clear evidence that exhibit heightened average boldness, exploration, activity compared nonurban conspecifics, result was robust among species, geographic region, ecological niche. Further, our results suggested “generalist” species have the strongest responses. Conversely, did not find strong linking variation, repeatability, or correlations. Our summarize data rapidly evolving field ecology demonstrate geographically taxonomically widespread behavior between populations, suggesting parallel selection across
