As migration ramps up, hundreds of millions of birds are on their way north to their breeding grounds, mostly flying by night.  Migration is a strenuous activity made all the more hazardous by artificial lights, especially at night.  Artificial light can provide safety and comfort, but it can also be disruptive and even dangerous for wildlife. The bright lights of a city and even the glow of lights from a seemingly quiet suburban neighborhood can cause birds to become disoriented.
