Baby water vole
Adults for comparison
A lot of vole traffic yesterday - at least two adults but I suspect more, plus this very appealing baby. The colour hasn't come out well in the photo, but young water voles are darker than the adults - plain chocolate-coloured - and much rounder, like a squashed pom pom. They leave the nest at just over three weeks, so I'm guessing this one is about a month-to-five weeks old.
