Watching the birdies

I don’t get many visitors apart from the birds. These are all sparrows. They take no notice of me now unless I move suddenly. How they can land on a little perch without hitting the window, I don’t know. But they do it every time. There’s also a pigeon who likes to sit on the window ledge. To begin with he was looking for spilled seed. Now it seems he just like it there, but will he poop? (He pooped.)
