ABSTRACT We found a stable pattern of geographic variation in songs across the breeding range Geothlypis philadelphia (Mourning Warbler) over 36-year period. The Western, Eastern, Nova Scotia, and Newfoundland regiolects 2005 to 2009 also existed 1983 1988 2017 2019. Each regiolect contained pool syllables that were unique different from other regiolects. primary syllable types defined each present throughout study, but there changes frequencies variants these regiolect. developed an agent-based model birdsong learning within explore whether frequency consistent with unbiased copying or 2 forms transmission bias: bias content bias. Strong bias, possibly for more complex syllables, best models temporal dynamics In combination high estimated fidelity, this may explain why 36 years. examined physical parameters song time could be attributed acoustic adaptation habitat, using Landsat variables as proxy vegetation characteristics male’s territory. songs, which changed little time, revealed no coherent relationships therefore evidence adaptation.

Abstract Local habitats shape animal vocalizations through selection to improve transmission of signals receivers. This process can be variable, however, when landscapes are changing continuously due urbanization or other factors. Studies have shown that some birds alter the frequency, amplitude and structure their songs in urban habitats. Because songbirds learn from individuals, this cultural result substantial change over time. Urban bird populations may therefore show rapid shifts song form variation combined interacting effects time anthropogenic habitat change. In study, we used historic recent recordings investigate changes spotted towhee (Pipilo maculatus) 45 years across an urban-to-rural gradient northern California. We found pre-trill trilled parts covaried differently with development at two time-points, more occurring trill phrases than pre-trills. Additionally, 1970 adjusted trills areas by raising maximum frequencies broadening bandwidths, while 2015 narrowed bandwidths decreasing areas. These results did not fit our prediction would a consistent effect on time-points. suggest habitat, evolution drift act elements complicated ways vary

'Cumulative cultural evolution' broadly describes the process by which traits accumulate improvements to efficacy over generations of social learning and innovation. The term can arguably be applied without much controversy evolution tool use, for example. However, it has recently gained momentum in aesthetic realm as well, where been used describe changes sexually selected traits. These, argument goes, gain sense evoking stronger emotional responses from receivers. Here, we use examples birdsong literature outline our objections application cumulative that achieve popularity based on no standard other than or sexual preference. Moreover, distinguish between categories are preferred different functional reasons, presenting arguments against describing each improvements. We conclude proposing a detailed nuanced understanding mechanisms outcomes change is more service behavioural science fraught binary distinction what cannot label 'cumulative'.
