i live in middle tennessee and have noticed the last few weeks the absence of birds no song birds not even a black bird this is unusual for our yard because we have always feed the birds and have a lot of them my elderly parents live on the other side of town and she ask me about 2 wks ago if i had seen many birds and i said no she seemed very surprised she had not seen any could this be any way linked to a future quake of the new madrid fault also i have had many headaches lately and for some reason have gotten very intersted in quake activity in just this last month i hope this is nothing but it does concern me about the birds
