I don't have any estimates for coal handy, but here are some other numbers for reference: Syncrude says their tar sand surface mining operations (the most extensive form of oil mining in wide practice) kill 2.5 birds/PJ. For wind power, estimates of annual bird deaths for the U.S. circa 2013 include 234,000[1], 440,000[2], and 573,000 (including 83,000 raptors and not including 888,000 bats)[3]. EIA says wind made 507 PJ in 2012[4]. So it's something like 800/PJ. For the U.S., a 2014 meta-analysis[5] gives 600 million[6] fatal collisions with buildings each year. A 2013 study says, "free-ranging domestic cats kill 1.3–4.0 billion birds and 6.3–22.3 billion mammals annually".[7] Ivanpah made 74 MW of solar electricity in 2015 (644,506 MWh, according to EIA). So 2600/PJ.
