Something’s moving

There’s something moving in the field next to Einar. I can see flower stalks trembling. It’s moving along behind the wall. All I can see is the movement it’s causing.

Then it pops up onto the barbed wire above the wall. It’s a Wren.

It gives a great view of its supercilia, it’s pale eyebrows, from the front.

Then it’s off, behind the wall, hunting and twitching the flower stalks as it goes.
