Last year we had mice. This year, birds have invaded our house.
We've got a woodpecker who knocks his head against our bedroom wall every day. Thank god he works the same hours as me. Otherwise, I'd have to get the sawzall out.
We also have a bird who's moved into our stain glassed window and built a nest. The window was conserved a few years ago and a plexiglass sheet was mounted inside to keep the wind from blowing in. But it means that we can observe the bird from inside, like one of those old anthills that kids used to have. Seems a shame to evict the bird.
