There is growing interest in latitudinal effects on animal behaviour and life history. One recent focus birdsong, which hypothesized to be more elaborated or complex the north temperate zone compared with tropics. Current evidence mixed based cross-species comparisons, single species restricted distributions. We circumvent these limitations using a transcontinental sample of 358 songs from house wrens ( Troglodytes aedon ) at 281 locations spanning than 100° latitude (52° N–55° S) across Americas. found significant gradient several basic elements song performance complexity between tropical populations. Furthermore, we document convergence patterns populations higher latitudes Northern Southern Hemispheres. Effects were strongest for number song, rate element production, both increasing towards poles, similar but weaker other dimensions (e.g. unique elements, trills trill rate). consider possible causes related variable habitats morphology, concluding that shorter breeding seasons hemispheres may favour greater elaboration mediate territory competition mate choice.

Songbird syntax is generally thought to be simple, in particular lacking long-distance dependencies which one element affects choice of another occurring considerably later the sequence. Here, we test for sequences songs produced by song sparrows ( Melospiza melodia ). Song sing with eventual variety, repeating each type a consecutive series termed ‘bout'. We show that switching between types, follow ‘cycling rule', cycling through their repertoires close minimum possible number bouts. do not cycle set order but rather vary types from cycle. Cycling variable strongly implies dependencies, next depends on sung over past cycle, range 9–10 also ‘bout length whereby repetitions bout positively associated interval until recurs. This rule requires even longer distance cross another; such are characteristic more complex levels than previously attributed non-human animals.

Abstract Many vocalizing animals produce the discrete elements of their acoustic signals in a specific sequential order, but we know little about biological relevance this ordering. For that, must characterize degree by which individuals differ how they organize sequentially and relate these differences to variation quality fitness. In study, fulfilled tasks male collared flycatchers (Ficedula albicollis). We characterized order syllables with network analysis approach studied consistency variables on distinct time scales (within day, between days, years), assessed relationship such indicators like age, body condition, arrival date, fitness related proxies survival next year pairing success. found that were associated nonrandomly one another both frequency consecutive number motif types higher original than randomized syllable sequences. Average small-worldness showed considerable among-individual decreasing repeatability increasing scale. Furthermore, relationships age average among within individuals. Accordingly, older males sequences using common less often younger However, no fitness-related variables. conclusion, organization birdsong has potential encode individual-specific characteristics, thus could be used as signal social interactions potentially subject sexual selection.

Breeding dispersal is the movement of an individual between breeding attempts and usually associated with disruption social pair bond, although mates may disperse together as a unit. In monogamous territorial species, decision to be affected by attributes such sex, age condition disperser. However, environmental contexts also play crucial role in disperse. We analysed capture‐resighting data collected over 9 years study divorce rates Southern House Wren Troglodytes aedon musculus population South Temperate Argentina. Between‐season was more frequent than within‐season dispersal, females dispersing often males, both within seasons. Both between‐season probability territory availability, but not previous success. When adult sex ratio ( ASR ) skewed towards male mating status, widowed single males paired males. Within‐season increased reproductive success availability partners (with increasingly male‐skewed ). Our results suggest that vacancies opportunities affect resident Wrens, highlighting importance for behaviour stability bonds.

Anthropogenic noise (≤ 3 kHz) can affect key features of birds’ acoustic communication via two different processes: (1) song‐learning, because songbirds need to hear themselves and other birds crystallize their song, (2) avoidance song elements that overlap with anthropogenic noise. In this study we tested whether reduces the number in repertoire House Wren Troglodytes aedon , an urban species. Additionally, proportion high‐frequency (i.e. where minimum frequency is above related levels, how frequencies duration shared between males change levels We recorded 29 exposed (36.50–79.50 dB) during consecutive breeding seasons from four locations. each male on 2 days season continuously for 50 min (we collected 104 h recordings) measured every 10 inside territory recording period. general, individuals inhabiting noisier territories had smaller repertoires. However, only locations 38.60 79.50 dB did have lower (36.50–66.50 dB), was not size. Individuals noisiest location showed a tendency include more songs. 26% elements, affected features.

Theory proposes an adaptive relationship between male song complexity, including large repertoires, and improved breeding success. Evidence supporting these relationships exists but is sometimes mixed or weak. Here we provide a first comprehensive study of the diversity success in non‐migratory, austral population house wrens Troglodytes aedon chilensis Mendoza, Argentina. During two‐year field study, measured for 62 males recorded more than 34 000 songs from subsample 26 males. For latter subsample, tested correlations six measures four canonical annual Males that sang with greater overall syllable type had larger repertories paired females bred earlier laid eggs over course season. However, also showed lower levels immediate diversity, as by Levenshtein distance successive songs. We discuss implications evolution complexity this exceptionally widespread species selective mechanisms might influence resident populations Neotropics compared to migratory northern hemisphere.
