Just before lunch, we pulled up to a dead end at the base of the foothills and looked out into a plowed field to see … yet another magpie. This one, though, was hopping and flashing its wings in jerks, as if trying to perform a mad waltz, so we drew up our binoculars for a closer look. We could see then that it was corralling a small rodent, a vole I guessed, as it danced from foot to foot.
