Bird on the Sidewalk

There was a bird on the sidewalk on our way home. It did not move when we approached. I nearly stepped on it before I saw it. Upon closer inspection, it looked like it was shivering.

"Is that a thing? Can birds shiver?" I asked my friend.

"Where did it come from?" she asked.

"I guess it must have fallen," I said.

"Is it hurt?"

"Maybe it's dazed. It shouldn't let us get so close."

It did let us get close. I was not entirely sure if it was looking at us at all.
