Whimbrels, shore birds make long distance flights to migrate with the seasons. One bird flew for 145 hours. This reqires metabolic changes with enough fat on board as well as muscle building prior to the jump. And then one might ask how did Darwinian evolution theory provide for this? Was there a first brave bird who took the chance because he 'knew' the benefits of warmer weather? This is all instinct, developed how? Darwin has no answer for any of this, that is obvious.
