Watching some rooks, when they started getting agitated, took a picture of them, then swung around to find what had troubled them. A buzzard.
I tried to operate the zoom and took a picture but it turned out to be empty sky. When I tried another, it merged into the branches of a row of trees in the background.
There are a lot more buzzards round here than there used to be 10 years ago.
Has anyone noticed this increase where they are?
