Recovering woodpecker

I was in the basement stoking the wood stove when I heard the thud at the kitchen window, and that usually means one thing: a bird has flown into the glass and now lies on the ground. My hope, as I grabbed my camera and raced outdoors, was that the errant critter was simply dazed and would eventually fly away. But for that to happen, I'd have to stand guard, since at least one of the cats was outside on a chilly but sunny day. The collision victim was a Downy Woodpecker—I'm making this tricky assessment based on the bird's relatively small overall size and bill length—and aside from the fact that it was just lying there, I had a feeling that it would recover. It didn't appear to have a broken neck, and though it didn't seem inclined to leave, it also didn't look like it was about to expire. Its eyes appeared addled, but they remained open. I stood watch, and in a few minutes, it took off, first, to the relative safety of a picnic bench and then, after another rest period, to the genuine safety of a nearby oak. Perhaps it learned something from the experience.
