... not to mention the free fertilizer produced from the huge number of rotting birds that flew into the turbines.
Wind turbines kill between 214,000 and 368,000 birds annually —
a small fraction compared with the estimated 6.8 million fatalities from
collisions with cell and radio towers and the
1.4 billion to 3.7 billion deaths from cats, according to the peer-reviewed study by two federal scientists and the environmental consulting firm West Inc.

According to the current literature somewhere between 140,000 and 328,000 birds die each year from collisions with wind turbines.
smithsonian.com and Audobon Society
With more than 49,000 individual wind turbines now exist across 39 states, that's about 4.5 birds per year per turbine.
I probably hit 2 per year with my car.
Pv on the other hand
As a renewable energy sources, solar energy has intermittency issues; not shining at night but also during daytime there may be cloudy or rainy weather.
Intermittency and unpredictability of solar energy makes solar energy panels A less reliable a solution.
Solar energy panels require additional equipment (solar inverters) to convert direct electricity (DC) to alternating electricity (AC) in order to be used on the power network.
For a continuous supply of electric power, especially for on-grid connections, Photovoltaic panels require not only Inverters but also storage batteries; thus increasing the investment cost for PV panels considerably
As mentioned, land-mounted PV panel installations require relatively large areas for deployment; usually the land space is committed for this purpose for a period of 15-20 years – or even longer.
Solar panels efficiency levels are relatively low (between 14%-25%) compared to the efficiency levels of other (Wind) renewable energy systems.
Though PV panels have no considerable maintenance or operating costs, they are fragile and can be damaged relatively easily; additional insurance costs are therefore of ultimate importance to safeguard a PV investment.
I am around these towers weekly (could it with thrown stone) and rarely hear them, never seen a bird strike, still have all my hair and my junk works.

On the other hand, just down the road I see acres of PV consuming grazing land falling into dis-repair,.
