The quality of these photos is not brilliant because I took them through the window for obvious reasons.
As I regularly put food out for the sparrows, the pigeons have caught on that they'll be getting a free dinner from the mess that the smaller birds make.... so they line up on the kitchen roof waiting like vultures to seize their opportunity.
Meanwhile, next door's cat stretches out on my small shed roof in whatever sunshine he can find and the birds carry on feeding in an unafraid way.
Occasionally the cat jumps down and tries to seize one of them, just to let them know who is in charge. He's getting too old and very rarely does any damage to them.
So life goes on.
