The Wild Bird Fund posted this on their Facebook page (I’m sorry for the upsetting photograph, but I’m hoping it will lead to your emailing these people, as it did for me):
One morning, one building: 28 birds dead, 2 found alive. These are all migrants, most have flown thousands of miles to be here only to crash into a condo building’s windows.
This happened at Circa Central Park, a glass-fronted building recently constructed right next to Central Park, one of the most important migratory stopovers on the East Coast. These deaths occur daily here every spring and fall.
There are many solutions, but the building owners have to implement them. If you’d like to voice your concerns, consider calling or emailing: http://circacentralpark.com/contact
And if you’d like to help us during this intense time, we thank you: bit.ly/wbfdonate
