Break-in

...of Pigeons.
I woke up with oorhh, oorhh, oorhh, oorhh just outside my door. I went to see what it was all about, and found a Pigeon in the stairway. I chased it until it found its way out one floor down (where it had found its way in). Then I went back to my appartment. Just as I was going inside I heard some oorhh, oorhh from the attic floor above me. So there was one more break-in-Pigeon! I went up to chase it out too. It had to fly two floors down to find the way out. Now that balcony door is closed.
