No- Not in the country. It takes something very unusual to kill the local birds in noticeable number.
In the city of Minneapolis, while I was doing property management years back:
My heating and plumbing contractor came to do some work during an unusual cold snap similar to the one we're experiencing now. They were late and looked very tired and run down, so I asked what was going on. Lots and lots of hearing system failures of buildings with natural gas fired steam or hot water systems was the answer.
Birds (pigeons mainly) were standing around the tops of old brick chimneys in large numbers to warm themselves with the stack gasses. As these heating systems were running pretty much full time the birds were succumbing to either oxygen deprivation or carbon monoxide poisoning. A percentage fell down those chimneys that were missing grates or screens... When enough had fallen down to block the chimney, the heating systems went down. And Pete & Larry had to go clean out the piles of bodies...
