  An expansion of the electromagnetic form factors of the nucleon and
Delta(1232) in small momentum transfer and pion mass is performed in a
manifestly-covariant EFT framework consistent with chiral symmetry and
analyticity. We present the expressions for the nucleon and Delta(1232)
electromagnetic form factors, charge radii, and electromagnetic moments in the
framework of SU(2) baryon chiral perturbation theory, with nucleon and
Delta(1232)-isobar degrees of freedom, to next-to-leading order. Motivated by
the results for the proton electric radius obtained from the muonic-hydrogen
atom and electron-scattering process, we extract values for the second
derivative of the electric form factor which is a genuine prediction of the p^3
BChPT. The chiral behavior of radii and moments is studied and compared to that
obtained in the heavy-baryon framework and lattice QCD. The chiral behavior of
Delta(1232)-isobar properties exhibits cusps and singularities at the threshold
of Delta->pi N decay, and their physical significance is discussed.
