I think they pretend they have schemes for keeping the birds away by broadcasting sounds of some kind. In fact they don’t really give a sh*t... and neither do any of the “animal rights” people.
Only one thing matters to all leftists everywhere: the advance of socialism and the destruction of the United States. Wind farms are just one small cog in the machinery of that advance.
I’ve heard of environMENTAL groups protesting wind power because of all the birds being killed. Some environMENTALists also protest solar panels in the desert because of the impact on species there.
