Jim Landau notes: "Another peculiarity about the Pinnacle Hen was that
she laid square eggs.  This was a good and sensible thing, for it
prevented them from slipping out of the nest and rolling down the
mountain."

Actually, seabirds that nest on ledges lay conical eggs, (unlike the
oval shape of hen's eggs,) with the result that if they roll they will
roll in a tight circle and be less likely to fall off the ledge.
