Relationship between laying sequence and mercury concentration in tree swallow eggs

Relationship between laying sequence and mercury concentration in tree swallow eggs

When female birds lay eggs, some of their body burden of mercury is eliminated into each egg, potentially leading to declining mercury across the clutch. However, there was no decline in mercury with laying sequence in clutches of tree swallow (Tachycineta bicolor) eggs at a mercury‐contaminated sit...

Zusammenfassung:When female birds lay eggs, some of their body burden of mercury is eliminated into each egg, potentially leading to declining mercury across the clutch. However, there was no decline in mercury with laying sequence in clutches of tree swallow (Tachycineta bicolor) eggs at a mercury‐contaminated site, presumably due to daily replenishment of mercury in females during laying. Sampling just one egg from the nest provided an accurate measure of clutch mercury contamination. Environ. Toxicol. Chem. 2010;29:1155–1159. © 2010 SETAC
