Abstract Migrating blue-winged teal (Anas discors) were collected in April (n = 48) and September (n = 53) 1983 on the Southern High Plains Region of Texas. Liver and breast muscle were analyzed for 14 trace elements, and tibias were analyzed for Pb content. Data were analyzed statistically to determine differences in concentrations between seasons, sexes and age classes. Concentrations of B, Cr, Mo, Pb, Zn, Hg, Cu and Se in livers, and of B, Cu, Mo, Pb and Se in muscle, were greater in autumn- than in spring-migrating blue-winged teal. Lead concentrations in livers, muscles and tibias reflected apparently low-level, chronic, oral exposure to this metal. Concentrations of Cr, Ni, Pb and Cu in livers, and of Cr and Zn in muscle, were greater in males than females. Greater Cd concentrations in livers of adults than in juveniles were attributed to the persistence of Cd in tissues. The trace metal concentrations we observed in our blue-winged teal samples generally were not sufficiently high to produce adverse physiological or reproductive effects.
