On the Vulnerability of avian populations to renewable energy production

There is a great cover up going on about the mass anthropogenic killing machines of birds, bats, and insects a.k.a. renewable energy production facilities (wind and solar. Caution: satire).

And where are these killing machines mostly made: China (Communist Party of China). Why do Western countries by these killing machines and thus become dependent on China?

On a daily basis we reminded by environmentalists etc. of the irrecoverable loss of biodiversity!

From the abstract:

"Renewable energy production can kill individual birds, but little is known about how it affects avian populations. We assessed the vulnerability of populations for 23 priority bird species killed at wind and solar facilities in California, USA. Bayesian hierarchical models suggested that 48% of these species were vulnerable to population-level effects from added fatalities caused by renewables and other sources. Effects of renewables extended far beyond the location of energy production to impact bird populations in distant regions across continental migration networks. Populations of species associated with grasslands where turbines were located were most vulnerable to wind. Populations of nocturnal migrant species were most vulnerable to solar, despite not typically being associated with deserts where the solar facilities we evaluated were located. Our findings indicate that addressing declines of North American bird populations requires consideration of the effects of renewables and other anthropogenic threats on both nearby and distant populations of vulnerable species."

Figure 3. Vulnerability (ranges from 0 (low) to 1 (high), as defined in Methods) after increases in simulated deaths for local (○) and non-local (▪) populations of 23 priority bird species found dead at (a) solar and (b) wind energy facilities in California, USA. Species in black were classified as moderately vulnerable (vulnerability greater than 0.2 after simulated fatality of 5000 adult individuals). Those highlighted in red were classified as highly vulnerable (vulnerability greater than 0.2 after 1000 additional deaths) based on effects on populations in local or non-local catchment areas. Vertical lines connect local and non-local populations. The five species with names in bold were found dead at both types of energy facility.
