Twice a year, the city kills thousands of birds during the great spring and fall migrations. Estimates range in the many millions for total number of birds killed by bright lights in big cities full of transparent glass, a mortality second only to habitat destruction. This black and white warbler was taken out by a highrise on the Upper West Side and fell onto my friend the Commodore's balcony. He sent me this pic.
There are efforts to stop this passive slaughter, but we continue to blunder on, literally burning the midnight oil, devouring the future, sterilizing the planet, on such a huge scale that it often seems that such ameliorative efforts are more for our consciences than anything else.
