Birds living near airports advance their dawn chorus and reduce overlap with aircraft noise (2015, unknown): “A previous study has shown that birds that are waken up earlier do start to sing earlier (Arroyo-Solis et al. 2013), but our results suggest that birds may anticipate the occurrence of aircraft noise, or else be selected to sing earlier.”
Seize the night: European Blackbirds (Turdus merula) extend their foraging activity under artificial illumination (2015, background): “Another striking adaptation to city life is the advanced dawn song of urban passerines, which has been attributed to both LAN and anthropogenic noise (Fuller et al. 2007; Miller 2006; Nordt and Klenke 2013; Kempenaers et al. 2010; Arroyo-Solı́s et al. 2013; Bergen and Abs 1997).”
Artificial night lighting rather than traffic noise affects the daily timing of dawn and dusk singing in common European songbirds (2014, background): “Lastly, it has been demonstrated experimentally that noise advances the first song of 2 out of 6 studied species (spotless starling Sturnus unicolor and house sparrow Passer domesticus; Arroyo-Solís et al. 2013).”
