Eye catching light: Anthropogenic light at night and its evolutionary influence on the avian eye.

ABSTRACT: Variation among avian species in their responses to artificial night lighting was recently linked to differences in dim light vision, but whether dim light vision is under selection from human-caused night lighting is unexplored. Here, we approximated dim light vision using eye geometries from museum specimens of six species collected across 100+ years and sought to determine whether proxies for artificial night lighting were related to within-species variation in dim light vision. We found variation in dim light vision was strongly linked to artificial night lighting proxies for three species and weakly linked for a forth, but the relationship varied by species. This variation is likely related to differences in ecological traits and may also reflect whether artificial night lighting faci
