The article cites a study on concentrations of metals in feathers and blood of nestling black-crowned night-herons in Chesapeake and Delaware Bays. Researchers stated that concentrations of metals in feathers reflect levels in blood at the time of feather formation, either from current dietary exposure or mobilization from internal organs. As heavy metals are poorly transferred from the hen into the egg, with the exception of organic forms, such as methylmercury, concentrations in nestling feathers were presumably reflective of post-hatching dietary exposure. |
