Saw this unusual sight down by the old canal. Hundreds of pigeons pecking away at the bricks on either side of the lock gate. Most of the birds flew away as I approached, settling noisily on the roof of an adjacent church. However, twenty or so hardy souls continued to peck away at the grouting, their beaks firmly below the waterline. Occasionally a pigeon would lose its hold and fall with a splosh into the canal. Amid much screeching it would right itself and rise , wet and dishevelled , skywards. Plumed inelegance. Who knew pigeons could swim ? What could they have been eating that made them so reckless ? The remarkable in the unremarkable.
