Animal communication plays a crucial role in biology, yet the wide variability vocalizations is not fully understood. Previous studies birds have been limited taxonomic and analytical breadth. Here, we analyse an extensive dataset of >140 000 recordings from 8450 bird species, representing nearly every avian order family, under structural causal model framework, to explore influence eco-evolutionary traits on acoustic frequency characteristics. We find that body mass, beak size, habitat associations geography characteristics, with varying degrees interaction song acquisition type. no evidence for vegetation density, sexual dimorphism, range size competition our measures Our results, built decades researchers’ empirical observations collected across globe, provide new breadth about how processes shape communication.
