Related topic? Wind turbines.
Bill Evans is a familiar name from my days in the Syracuse/Cornell area of New York State. Here is an article I just found that he was interviewed for in Syracuse; note that it is 3 years old. Thought about placement of wind turbines is in all our minds these days. Much more has been learned since then,no doubt.

Forgive if this is OT or otherwise irrelevant.There are other articles under "Bill Evans ornithologist" online.

Hi,
Some people use special microphones and tape the night migration calls, then run them through software to ID using spectrograms. Although sparrows sound different from warblers, for example, a lot of warbler calls can sound pretty similar and spectrograms can help sort out very similar ones if that is of interest to you. There also are audio recordings of many flight calls. Here is one website with information on all of this, including how to build your own microphone, and also with a CD ROM guide that includes audio versions, spectrograms, and other info. The guy who put all this together, Bill Evans, is extremely knowledgeable about night flight calls and also generous in sharing that knowledge.

Can someone please tell me how to identify what I am hearing overhead at night ????? Migration is certainly going great right now and will only increase but I am frustrated sitting in my Adirondack smoking a cigar and drinking a beer while listening to all the activity overhead and not having a clue as to what they are. After an hour or two I go inside and my wife asks me what I heard and all I can tell her is a chip here a chirp there and sometimes a double or triple chip or chirp while having no clue as to what they are. Any help would be greatly appreciated !!!!!Mark R HoffmanNewcastle Maine207-458-1897--
