Noise pollution is increasingly recognized as a critical environmental stressor affecting avian species worldwide. Birds depend heavily on acoustic signals for communication, reproduction, predator avoidance, and social interaction. Anthropogenic noise from urbanization, transportation, and industrial activities interferes with these acoustic signals, forcing behavioural adjustments that may compromise survival and fitness. This paper explores the impact of noise pollution on avian behaviour, focusing on vocal communication, mating success, foraging efficiency, vigilance, and parental care. It also examines case studies, including findings from India, to highlight the regional implications of this global issue.
