Abstract

Mercury concentrations were measured in blood, down, and feathers from approximately 300 wood stork nestlings in one South Carolina, USA, and four Georgia, USA. colonies from 1996 to 1999. Coastal nestlings generally had lower mercury concentrations than those from inland colonies. Interyear differences were also apparent, particularly for coastal colonies, where nestlingmercury concentrations were higher in 1998 than in 1997 or 1999. In 1998, a wet winter followed by a dry spring and summer produced ideal freshwater foraging conditions and mercury concentrations in coastal nestlings were higher than during the two dry years. There was little interyear variation inmercury concentrations in nestlings from inland colonies. as parent stories from these colonies forage exclusively in freshwater habitats regardless of rainfall patterns. These results suggest that greater risk of mercury exposure to nestlings is associated with use of freshwater foraging habitats.
