  abstract = {{E}nvironmental variation shapes acoustic interactions among birds, creating spatial structures in the sonic signature of local species assemblages. {E}xploring these patterns at regional scales can reveal processes that segregate acoustic strategies along environmental gradients. {H}ere, we examined how the acoustic trait composition of bird assemblages varies at a regional extent in relation to landscape resolution environmental variation. {W}e used data on 2427 bird assemblages and 15 acoustic traits, quantifying the frequency, complexity, rhythm, and duration of vocalisations for 117 species. {W}e used multivariate ordinations to investigate the distribution of species' acoustic traits along climatic and landscape gradients while accounting for spatial and phylogenetic dependencies. {W}e then assessed whether these relationships resulted in directional shifts in the acoustic trait composition of bird assemblages for three key acoustic traits. {O}ur results show that acoustic traits were phylogenetically and spatially clustered and correlated with regional climatic conditions (e.g. lower complexity and isochronous rhythms under higher precipitation and temperature seasonality). {C}onversely, we found mixed support for the hypothesis that the acoustic signature of species assemblages is shaped by habitat composition within landscapes. {F}or instance, we found urbanisation to be associated with vocalisations featuring broader spectral bandwidths, likely facilitating their propagation under noise pollution, but also greater complexity, which may hinder transmission in urban landscapes. {T}hese regional patterns may reflect differences in the structure of acoustic networks within and among species assemblages. {O}ur results thus form a first step towards a regional-level assessment of the environmental and anthropogenic factors that structure or disrupt acoustic connectivity in landscapes.},
