Lead in piscivorous raptors during breeding season in the Chesapeake Bay region of Maryland and Virginia, USA
ABSTRACT Sources of lead exposure of many bird species are poorly understood. We analyzed blood lead concentrations from osprey ( n = 244; Pandion haliaetus ) and bald eagles ( n = 68; Haliaeetus leucocephalus ) and documented potential sources of lead they may encounter. Adult bald eagles had highe...
