Squirrel maintaining a nut (Period)

The squirrel is a small tree-dwelling beast of the rodent family, whose medieval reputation was of diligence and, oddly, anger.  It is a period charge, found in the arms of Hadlaub, c.1340 [Zurich 478].

The squirrel is sejant erect by default.  In that posture, it’s often drawn maintaining a nut between its forepaws, even when not specifically blazoned (though it frequently is).
