speaking of like a bird on a wing

a small bird (wren? sparrow?) just flew into the glass door next to me. 

it crumpled to the ground, twisted and trembling. 

i thought its beak fell off.

after 5 minutes it wasn't moving, i went to get a broom, and i pushed it with the broom just a little.

it ruffled its feathers and sat up straight. 

it stayed frozen there.

i was pretty sure it was dying and considered putting it out of its misery. smack it with the broom? fling it in the woods? let the dogs get to it?

5 minutes later it up and flew away.

moral: sometimes birds take a little while to gather themselves up after a crash, they are not necessarily dead or dying.
