Ingestion of lead and nontoxic shot by Green-winged Teal (Anas crecca) and Northern Shovelers (Anas clypeata) from the mid-Gulf Coast of Texas, USA.

ABSTRACT

Ninety-eight Green-winged Teal (Anas crecca) and 84 Northern Shoveler (Anas clypeata) gizzards were examined for ingested shot. One Northern Shoveler had lead and three had steel shot; 24 teal and 17 shovelers had composite nontoxic shot or nonlead metal fragments. Prevalence of ingested lead appears minimal and consistent with other studies conducted after lead-shot bans.
