Clapper Rails (Rallus longirostris) can potentially serve as an indicator species of estuarinemarsh health because of their strong site fi delity and predictable diet consisting predominantly of benthic organisms. These feeding habits increase the likelihood of individuals accumulating signifi - cant amounts of contaminants associated with coastal sediments. Moreover, since Clapper Rails are threatened in most of their western range, additional study of the effects of potential toxins on these birds is essential to conservation programs for this species. Here we present techniques (DNA strand breakage, eggshell structure, and human-consumption risk) that can be used to quantify detrimental effects to Clapper ...
