Bird in the hand

I've been lying  around, using a circulating ice machine for my operated-upon left knee (torn meniscus, thanks to dumb down-hill running during Dipsea Race). Walked out into living room a half hour ago and a little bird was flying around inside. I hobbled around after him, opening windows, but he kept flying into another room and banging into the glass on windows as he tried to escape. Finally I was able to pick him up. Took him outside and he made a few attempts to fly and just fluttered to the ground. I kept him a while, shot a few pics, then he looked at me and flew away. Looks like a baby sparrow.
