Egg Mercury Concentration and Egg Size in Two Songbird Species

This dataset includes egg total mercury concentrations, egg total mercury burden, egg length, egg width, predicted egg volume, and predicted fresh wet weight according to egg position in the laying sequence for tree swallow and house wren eggs from the Cache Creek Settling Basin and Cosumnes River Preserve, in California's Central Valley during 2018. These data support the following publication: Hartman, C.A., Ackerman, J.T., Cooney, B., and Herzog, M.P., 2024.
