Survival of the most frequent

These pigeons are top of the bird sightings in our garden - everyday! They scare off the smaller birds. They perch in the same places and defecate mercilessly on our ivies and other delicate planting. Not sure what we can do about them. Their daily routine is procreating, eating and excreting. Hey ho!
New smart meters were fitted this afternoon. Hope these ones work. Our local grandchild turned ten today! Happy birthday!
