Assess how anthropogenic noise influences avian species richness and diversity across urban parks.
Concurrently monitored bird communities and equivalent continuous sound pressure levels (Leq) in eight urban green spaces over a 1-year period in Belo Horizonte, Brazil.
Quantified community diversity using total species richness, Fisher's alpha, and Shannon–Wiener diversity indices alongside habitat and socioeconomic variables.
Noise levels across all urban parks exceeded levels measured in baseline natural environments.
Species richness correlated negatively with increasing noise levels, surrounding open habitat, and socioeconomic urbanization metrics, with noise accounting for the largest share of explained variance.
