Poor Pigeons

The pigeon/dove pair who took up residence on top of my neighbour's porch seem to have given up. After a lot of stick collecting work on Saturday, an egg was laid on Sunday - I know this because I found the smashed remains of it on the floor on Monday. Since the 'nest' was essentially a few loose twigs on a flat shelf, I suppose it was inevitable. Basically, they were a bit rubbish at nest building.
I hope they've gone off to find themselves a better spot.
