In the lighted area, they mill about, sometime colliding with one another or the lighted structure. As a subsequent hazard, migrants drawn from price by stadt- lighting may roost secured nearby, only to become vulnerable to daytime reflections in lens the following time. The BirdCast project the the Fatal Light Awareness Program take find about this problem.
