More nonsense - more staring out of the window. From time to time we get a bad-tempered blackbird in the garden. I guess it's seasonal, and, since it's been going on for a good many years, it can't be the same individual. It must be a blackbird thing.
We have one now. He takes it upon himself to chase and generally intimidate all other living objects in the garden. In case we thought it was our garden, he keeps us aware that it's actually his.
It's not even a productive strategy. I just watched him abandon a good-sized worm in mid tug, and - presumably because something had caught his eye 50 yards away - he flew, screeching, into the wood at the foot of the garden, ready for a scrap. While he was distracted, the thrush that he had previously chased helped itself to the worm.
You know, I think there's maybe a lesson in there somewhere, if I could only think of it.
