In the United States, an estimated ioo million to one billion birds perish each year from encounters with buildings.
Bird injury or death is largely attributable to two factors: birds, it would appear, are unable to detect and avoid glass, either during the daytime or night. Moreover, buildings’ artihcial night lighting confounds night-migrating species. Today, preventative actions mindful of these hazards are emerging in building practice. With bird-safe measures at hand, we can avoid the adverse consequences that until recently seemed inevitable though unintended...
