Following the prescription of Moustakas et al. from earlier work on EROs in the GOODS southern field (CDF-S or GOODS-S), we compare the optical rest-frame morphologies of samples of x-ray and radio-selected EROs found among the larger GOODS sample. Using z-band ACS data will enable us to extend the study of rest-frame morphologies of these sources to z~1.3, avoiding the effect of morphological k-correction. The radio and x-ray can also be used as independent tracers of star formation, for example, and the comparison with HST morphologies can be used to search for visual evidence of star formation which may correlate with the presence of x-ray or radio emission.
