An evaluation of excrement as an alternative to blood for characterizing lead exposure in bald eagles

open access: yesWildlife Society Bulletin, 2016
Lead (Pb) exposure in free‐flying bald eagles (Haliaeetus leucocephalus) is an important conservation concern. One of the challenges to characterizing the magnitude of Pb exposure in free‐flying bald eagles is obtaining samples.
