Indigo Bunting On Hard Times

Last night, at work, a male Indigo Bunting was found on the sidewalk outside the store. It was apparently injured or in shock, possibly from collision with a window pane. It could fly only a very short distance, and did so when I tried to pick it up. When I left this morning it was still alive and huddled against the wall of the store. There isn't any decent bunting habitat in the vicinity, so I assume it to be a late spring migrant that made an unfortunate mistake during the night.
