Invasion of the Jackdaws

We were away from home overnight. When we returned the next morning, the sitting room fluttered furiously with four frightened jackdaws. (And yes, I'm pleased with that alliteration.)  They had come down the large open chimney and were now looking for the Exit sign. I caught each one individually and bid it adieu after opening the window.  They have good strong beaks which deliver a sharp peck. As soon as we could, we arranged for Jacob and his mate to fit a bird cowl on the chimney. Now the jackdaws are cross with us, and sit, cursing, on the top of the chimney.
