I spent some time at work yesterday, and was startled to hear sounds in the office when I knew good and well that I was the only person in the building. After a few minutes of listening, I realized that there was a bird trapped above the ceiling tiles, and I was able to ignore it.
This morning, one of my coworkers got too creeped-out by it, so we ended up removing one of the ceiling tiles so the bird could get out. About half an hour later, a young starling poked its head out, then flew into my office. It quickly found a window to flap against (our windows don’t open). I caught it and took it outside. When I turned it loose, it flew across the street, no doubt to tell its friends about the weekend it spent in durance vile.
