A view of the Empire State Building this afternoon. If you look closely you can see the window washing scaffolding. It seems like they are always washing the windows.
"During spring and fall bird migration seasons and particularly on cloudy, humid and/or foggy nights, when large numbers of birds are seen flying near the building, the tower lights are turned off. Observatory personnel on the 86th floor outdoor deck notify the engineers. The birds are attracted by the lights and there is a danger they will fly into the building and be killed."
