Took a last walk at dusk on the longest day. A barn owl was quartering the fields and we were probably both hunting the same thing – voles, since I was inspecting the small mammal traps I'd set to check on the vole population here. I hadn't caught any, but he did, swooping silently down to pluck one from the tussocky grass. A ketrel was hovering there too, hunting for the same thing, but it was getting a bit late for him since unlike the barn owl he was relying on sight not sound.
