Songbirds need their sleep to sing A bird’s song is crucial for it to attract mates and defend resources. With growing light and noise pollution disturbing birds’ sleep, could a bad night’s sleep change how they sing the next day? NZ researchers analysed the before and after chirps of 13 sleep-deprived myna birds, finding that sleep disturbances during part or all of the night altered how much they sang and how complex it was. While common mynas are tough city birds, the lead author says many native species aren’t as adaptable. That means they could be even more affected by sleep loss caused by urban life.
