A shorebird without a shore runs across Kansas gravel, flashes two breast bands, and sometimes performs an apparently broken wing to move danger away from eggs hidden in plain sight.

Kansas’s broadest weasel reads the prairie from below, opening prey burrows with long foreclaws and leaving fans of soil that may outlast the animal’s brief nocturnal appearance.
