Artificial night lighting affects dawn song, extra-pair siring success, and lay date in songbirds
(2010) In Current Biology 20(19). p.1735-1739- Abstract
- Associated with a continued global increase in urbanization[1], anthropogenic light pollution is an important problem[2]. However, our understanding of the ecological conse-quences of light pollution is limited [2–4]. We investigatedeffects of artificial night lighting on dawn song in fivecommon forest-breeding songbirds. In four species, malesnear street lights started singing significantly earlier atdawn than males elsewhere in the forest, and this effectwas stronger in naturally earlier-singing species. We com-pared reproductive behavior of blue tits breeding in edgeterritories with and without street lights to that of blue titsbreeding in central territories over a 7 year period. Underthe influence of street lights, females started egg... (More)
