It's a standard troll argument, yeah.

Over here, there have been groups who put dead birds (often roadkill) underneath wind turbines.

I think it's because they can see the birds that turbines kill. The birds killed the the pollution fossil fuels cause are hard to notice and especially hard to link to the cause of death. When there's dead birds around a turbine, it's more obvious.

People don't look at numbers. They're driven by emotions, which favour what they can easily see and wrap their heads around. Or alternatively, what they are most scared of. Eg, nuclear power is far safer and less radioactive than coal. But that doesn't matter. People are afraid of nuclear because of past incidents they heard about. The way coal kills people is so much harder to notice than a dramatic HBO series.
