>>12580125birds are more complex than insects, you fucking retard. what are you doing on the /sci/ board if you're too retarded to understand the difference between a bird and a fucking gnat. most insects produce hundreds, if not THOUSANDS of offspring, from a single coupling. their entire reproductive method involves throwing RNG at the wall until something sticks, then what stuck divides into fucking thousands more sticky wall balls. birds cannot just randomly evolve the instinct to avoid cars and wind turbines because their thought processes are considerably more complex, and they have significantly less offspring; vertebrate animals generally have sacrificed instinct and raw numbers for quality > quantity reproduction. insects have not done this, not at all in any fucking way. there are 350,000 different species of beetles alone, because all they do is shit out more beetles. a million beetles die to stupid bullshit, a few hundred beetles don't die to stupid bullshit. a few generations later and you now have a few hundred thousand beetles that don't die to stupid bullshit. some will still die to the stupid bullshit because there are just so many fucking beetles that it doesn't even matter. because that's how bugs work. the decline in bug populations is, among other things, modern pesticides, chemicals in the environment, habitat loss, etc.
