You lost track of the baby bird. What happened to it exactly? It is hard to tell from your perspective. A large bird turned into lightening around it, that is all you know. Maybe the baby bird turned into ionized gas. Maybe it got massive talons rammed into its sides. There is no way to determine exactly what happened there.
You tried to protect the baby bird. You violently protected it, actually. Perhaps passivity could have yielded more answers than questions, but the only way for you to really find out is to try try try again.
Oh yeah, you also put a rock on a bird to keep it warm. That was weird.
