Susan Elbin, Director of Conservation and Science at NYC Audubon, and colleagues published a paper today in the Proceedings of the National Academy of Sciences. The results of their yearly tally of birds in the lights between 2008 and 2016, somewhere in the neighborhood of 1.1 million migrating birds were affected by the light. Within 20 minutes of the lights going on the number of birds right there goes from 500 to 15,000.
Morgantown, West Virginia (right over the state line, directly south of Pittsburg) is getting new street lights. The LED lamps direct the light downward rather than all around in multiple directions. Not only will this benefit the animals, insects and birds in the area, the directed light is designed to prevent stray light from entering windows in high rise apartment buildings. The new fixtures were chosen to keep the style of the historic downtown intact.
