Noise pollution is increasing at an unprecedented rate, with documented impacts on reproduction and development across taxa. While recent research has focused on anthropogenic noise's effects on avian vocal behavior, particularly in high-noise environments like airports, its physiological impacts and consequences for avian sleep remain poorly understood. This study investigates how aircraft noise from Jorge Newbery Airport affects the respiratory activity of adult male canaries (Serinus canaria domestica) during both wakefulness and nocturnal sleep. Our results demonstrate that perturbations in respiratory rhythm are closely correlated with the positive rate of change in ambient noise levels caused by passing aircraft, with the most significant behavioral changes occurring at the peak of the noise derivative. Furthermore, we show that air sac pressure and respiratory rate exhibit similar response patterns but are affected differently. Collectively, these findings indicate that the physiological impacts of anthropogenic noise pollution are potentially more harmful than previously recognized.
