"Partridges exhibit another piece of cunning, combined with affection for their young. They teach their fledglings, who are not yet able to fly, to lie on their backs when they are pursued and to keep above them as a screen some piece of turf or rubbish. The mothers meanwhile lure the hunters in another direction and divert attention to themselves, fluttering along at their feet and rising only briefly until, by making it seem that they are on the point of being captured, they draw them far away from their young."
