Ambient anthropogenic noise but not light is associated with the ecophysiology of free-living songbird nestlings

Abstract Urbanization is associated with dramatic increases in noise and light pollution, which affect animal behaviour, physiology and fitness. However, few studies have examined these stressors simultaneously. Moreover, effects of urbanization during early-life may be detrimental but are largely u...
