yep, I am new here & have joined this am to find out why all the little sparrows are dying here in town. As of yesterday I had 11, as of today I now have 16, I contacted the DNR of Wisconsin wildlife biologist by email yesterday & saved the 5 birds that I found this am when filling the feeders, all birds are intact/froze. My feeling is the salt in SE Wisconsin is killing them off/ sodium poisoning, but I have yet to prove that. Just putting something out there as we are concerned. Shagbark
