Model-independent predictions for excitation energies, semileptonic form factors and electromagnetic decay rates of isoscalar heavy baryons and their low energy excited states are discussed in terms of the combined heavy quark and large N_c expansion. At leading order, the observables are completely determined in terms of the known excitation energy of the first excited state of Λ_c. At next-to-leading order in the combined expansion all heavy baryon observables can be expressed in a
