t'were a few summers ago, Like now had patio door open and was working. Became aware of right old racket of cawing from the local mob - a word I use advisedly as they do sound like machine guns.
Curiosity piqued, (and not being a cat) I went to see what was up. When I got to the door - silence.
Rinse and repeat twice more ....
I was left with the distinct impression it was a magpie version of knock down ginger (if that phrase places me in space and time).
On reflection I did wonder if maybe a cat had been prowling, and the canny corvids thought that by summoning me it would be scared off ?
Used to see loads of magpies on our front lawn - now replaced by crows. Although a neighbour said his little girls love seeing the sparrows on our lawn as they go to school. Which made me feel weirdly content. Any old bits of bread go on the law and are hoovered up within minutes.
Some birds are descended from dinosaurs so are clearly playing a long game. 😀
