"Are you suggesting that behavior can't be hardwired?" Like others mentioned, there is a difference between species who can learn it more easily and those who learn slower. https://en.m.wikipedia.org/wiki/Precociality_and_altriciality https://en.m.wikipedia.org/wiki/Precociality_and_altricialit... But some sort of learning (or callibration) is always required, because no individual is the same, so you cannot have it prehardwired everything. The basic movement of the muscles to fly, yes, but the exact movement and coordination needed to fly, needs the information of the specific mass and lengths of the wings etc. which are going to be different. In short, "the hardware" is organic and not standartized.
