  We extend an earlier study of the baryon magnetic moments in chiral
perturbation theory by the explicit inclusion of the spin-3/2 decuplet
resonances. We find that the corrections induced by these heavier degrees of
freedom are relatively small in a covariant framework where unphysical spin-1/2
modes are removed. Consequently, implementing the leading SU(3)-breaking
corrections given by both the baryon and decuplet contributions, we obtain a
description of the baryon-octet magnetic moments that is better than the
Coleman-Glashow relations. Finally, we discuss the uncertainties and compare
between heavy baryon and covariant approaches.
