Domestic and feral ex-domestic cats kill far more birds than either. If this is a real concern, banning cat ownership is top of the list.

  Source? Or is HN now Newsmax where evidence isn’t needed and statements alone serve as “facts”?

    Cats do kill a shocking number of small birds and other mammals. A conservative estimate is somewhere around 7 billion a year, and that's just in the United States. I have 4 cats myself but they never go outside. https://en.wikipedia.org/wiki/Cat_predation_on_wildlife https://en.wikipedia.org/wiki/Cat_predation_on_wildlife

Your statement is true - glass skyscrapers kill more birds than wind turbines. What if the number of wind turbines was equivalent to the number of glass buildings? Would your statement hold true? Or, a child comment makes a remark about house-cats killing more birds than wind turbines. What if the number of wind turbines was equivalent to the number of house-cats? You're not comparing like-to-like. If you're recommending scaling the number of wind turbines greatly (to combat climate change), you should instead consider a metric like ' number of birds killed per turbine per year' like 'number of birds killed per glass building per year' to at least get to the data.
