Flown the Nest

For the last three weeks or so, whenever I have looked up at a nest in a garden tree, there has been a pigeon sat there unmoving apart from a blinking eye, even when the cats have climbed up there, so I had begun to fear it was there for the duration probably trying to hatch out a broken, non-existent or unfertilised egg, however today it finally gave up and with a clatter of wings it was off; quite a relief really as I had begun to fear it would expire up there and require removal of remains.
