A plunge and flight

Do birds in learning and in flying on a daily basis at some point think about that flight is acceptance of the ability in/and possibility of plunging to their own death? Because it's there. A plunge and then a wind taking their wings and their bodily mechanics taking over. But there is a plunge.A plunge that would give a human being death. Or do birds just accept this and fly anyways? All this being irrational, of course. Birds are driven and operate 1000% by innate instinct and don't really think as we think. But the crust of it's there. Their ability to fly on a daily basis is based on their ability to accept the possibility of death.

What really fascinates me is there it is, physically before my eye-- now that it's spring, everyday I watch them take off from this huge tree right outside my window. There is a plunge! There's always a plunge. There's something in that plunge. There's something in that plunge that is both magical, graceful, spiritual and altogether... fascinating. Because there is always a plunge and then flight. A plunge and flight.
