In order to statistically infer merger redshifts, the ``spectral standard siren\" method relies on features, such as peaks, dips or breaks, in the compact object mass spectrum, which get redshifted in the detector-frame relative to the source-frame. However, if the source-frame location of these features evolves over cosmic time, the spectral siren measurement may be biased.
