Query: How to identify zero modes for improved staggered fermions   We present results of the eigenvalue spectrum for the staggered Dir\"ac
operator obtained using a modified Lanczos algorithm. We identify zero modes
and non-zero modes. We derive the chiral Ward identity derived from the
conserved $U(1)_A$ symmetry, and check it numerically. This is the first step
toward construction of an improved method to identify zero modes reliably with
staggered fermions.
