Junk science and guesswork!
Your first article has completely unprovable assumptions about 'climate change' - no surprise there.
"Looking at the mid-range scenarios in climate change expected by the Intergovernmental Panel on Climate Change, they projected that 15% to 37% of all species of birds could be extinct by 2050. These numbers, too, can be tentatively quantified into 9.16 deaths per GWh from oil, natural gas, and coal-fired power stations.4 "

I don't quite see your point about power cables. How do massive bird-killing wind farms deliver their electricity to consumers? Power cables.
I am all for putting power cables underground but the source of electricity is completely irrelevant.
