I have been trying to correlate flights as reported by NFC observations, and radar with our experience picking up window strikes in DC. Last night's reported flight in the northeast resulted in only a couple of warblers this morning. I wonder if any other Lights Out groups are getting different results? We should be able to declare emergency nights when we expect big flights- if only we can correlate. -TATE
