I don't know if anyone has an answer on this board, but something really strange happened to my wife and I on Sunday. We were driving from Altoona to Iowa City (my daughter plays soccer and they were scrimmaging the hoks). It was cold and snowy in the early afternoon, and we were driving on the back roads between Altoona and Colfax. There were literally hundreds of birds (mostly robins) that were sitting along the edges of the road. As we would drive by, they would fly/scatter and were not too effective at avoiding cars. We probably hit 4 of them in a 20 mile stretch and there were others laying dead in the road or beside the road. Really bizarre. Weather related?
Yep I noted the same thing around here when just driving to work. It looked weird because we had about 3" of snow but it all melted off the roads. Looked like someone had heated all of the roads So I think the birds were just in the grass near the road looking for food. I was only driving ~50 mph so I didn't hit.
