Open science approaches enable and facilitate the investigation of many scientific questions in bioacoustics, such as studies on temporal spatial evolution song, vocal dialects. In contrast to previous dialect studies, which mostly focused songbird species with a small repertoire, here we studied common nightingale ( Luscinia megarhynchos ), bird complex large repertoire. To study dialects population level this species, used recordings from four datasets: an open museum archive, citizen platform, project, shared academic researchers. We conducted date largest geographic birdsong including 1930 2019 13 European countries, geographical coverage 2,652 km linear distance. examine stability dialects, catalog 1,868 song types nightingales was created. Instead found high degree over time space both, sub-categories occurrence types. For example, second most type our datasets occurred nine decades across Europe. case study, data proved be equivalent, some cases even better, than by research group. Based results, conclude that combination diverse particularly useful

Abstract Radio frequency identification ( RFID ) provides a simple and inexpensive approach for examining the movements of tagged animals, which can provide information on species behavior ecology, such as habitat/resource use social interactions. In addition, tracking animal is appealing to naturalists, citizen scientists, general public thus represents tool engagement in science education. Although useful tool, large amount data collected using may quickly become overwhelming. Here, we present an R package feedr have developed loading, transforming, visualizing time‐stamped, georeferenced data, from static logger stations. Using our package, be transformed raw visits, presence (regular detections by over time), between loggers, displacements, activity patterns. several conversion functions allow users format other complementary packages. Data also visualized through or interactive maps animations time. To increase accessibility, either directly, companion site: http://animalnexus.ca , online, user‐friendly, R‐based Shiny Web application. This system used professional scientists alike view study movements. We designed this flexible able handle stationary sources (e.g., hair traps, very high VHF telemetry observations marked individuals colonies staging sites), hope framework will meeting point science, education, community awareness animals. aim inspire while simultaneously enabling robust scientific analysis.

The good parent hypothesis in sexual selection predicts that if females can increase their fitness by mating with males who provide high‐quality parental care, then female preferences for male phenotypes honestly indicating the quality of paternal care will evolve. In order to test this hypothesis, we investigated correlations between song, timing pair formation males, feeding rate, and reproductive success, bull‐headed shrike Lanius bucephalus (an altricial oscine passerine biparental care). Analysis revealed although was not correlated most song characteristics (e.g. repertoire size), morphological traits tail length), or territory size, it negatively singing tempo (i.e. number notes uttered per second). Those sang at higher speeds were better body condition mass standardized tarsus length 3 higher), fed chicks frequently during nestling period, raised heavy chicks. These results show is a condition‐dependent dynamic trait strongly supports hypothesis.

Most birds engage in extrapair copulations despite great differences across and within species. Besides cost benefit considerations of the two sex environmental factors have been found to alter mating strategies or between populations and/or over time. For socially monogamous species, main advantage that females might gain from with multiple males is probably increasing their offspring's genetic fitness. Since male (genetic) quality mostly not directly measurable for female birds, (extrapair) mate choice based on secondary traits. In passerines song such a sexual ornament indicating phenotypic repertoires seem affect number Yet role behavior well understood. this study, we investigated proportion paternity (EPP) population common nightingales Luscinia megarhynchos. We EPP rate was rather high (21.5% all offspring tested) species without dimorphism levels paternal care. Furthermore, occurrence strongly related spatial distribution territories settling densely occupied areas having higher proportions young own brood. Also, repertoire size affected EPP: here larger social mates were negatively probability being cuckolded. When comparing sizes mates, tended repertoires. finally discuss our results as hint flexible strategy where several factors-including ecological features-need be considered when studying reproductive complex song.

In many songbird species, birdsong features phonological syntax, meaning that the units within their vocal sequences are ordered in a non-random way adheres to rule. While such syntactical patterns have been richly described comparatively little is known about how those contribute song achieving its important functions. For each of song's main functions, territorial defense and mate attraction, evidence role for syntax limited. One species which has thoroughly Hermit Thrush (Catharus guttatus), present types from repertoires semi-predictable order and, doing so, rapidly cycle up down frequency spectrum. The objective study was explore importance through within-subject examination measures as predictability type sequences, shift over breeding season. We hypothesized that, if characteristics behaviour, they would be most prominent at start season when activity associated with territory establishment attraction intense. Analysis revealed predicted, rigidness ordering highest declined thereafter. That were predictable vitally early part fit our hypothesis this aspect functions related and/or attraction. Future work will clarify whether relates one two or serves transmission some broader way.
