This data consists of egg morphometric data from white-faced ibis. Eggs were collected in the field and then measured and dissected in the lab to obtain estimates of length, width and mass. This data supports the following publication: Herzog, M.P., Ackerman, J.T. and Hartman, C.A., 2021. Egg morphometrics and egg shape coefficients for White-faced Ibis (Plegadis chihi). The Wilson Journal of Ornithology.

California’s Central Valley is a nexus for water resources in the state, draining the Sacramento and San Joaquin River watersheds. Urban centers, agricultural operations, and the environment all compete for limited water, and demand is expected to only increase as the population grows and agriculture intensifies. At the same time, the water supply is projected to decrease as temperatures rise, precipitation patterns change, and the frequency of extreme droughts increases. The Central Valley also provides critical wetland habitats to migratory waterbirds, and wetland managers require information on how to best use water resources to support wildlife objectives, particularly during drought. This project seeks to...

Nest monitoring data of white-faced ibis. Data were collected at seven day intervals and provide information on success and failure of the nest during that interval. Summary vegetation and habitat data were also collected at the nest. These data support the following publication: Herzog, M.P., Ackerman, J.T., Hartman, C.A. and Browers, H., 2020. Nesting ecology of White-faced Ibis (Plegadis chihi) in Great Salt Lake, Utah. The Wilson Journal of Ornithology, 132(1), pp.134-144.

Methylmercury contamination of the environment is an important issue globally, and birds are useful bioindicators for mercury monitoring programs. The available data on mercury contamination of birds in western North America were synthesized. Original data from multiple databases were obtained and a literature review was conducted to obtain additional mercury concentrations. In total, 29219 original bird mercury concentrations from 225 species were compiled, and an additional 1712 mean mercury concentrations, representing 19998 individuals and 176 species, from 200 publications were obtained. To make mercury data comparable across bird tissues, published equations of tissue mercury correlations were used to convert...

These metadata provide data used to examine mercury and selenium concentrations in eggs of birds breeding in wetlands of the Great Salt Lake ecosystem, Utah, particularly at Bear River Migratory Bird Refuge. Eggs were salvaged during 2010 - 2012 and include 33 species of birds. These data support the following publication: Ackerman, J.T., Herzog, M.P., Hartman, C.A., Isanhart, J., Herring, G., Vaughn, S., Cavitt, J.F., Eagles-Smith, C.A., Browers, H., Cline, C., and Vest, J., 2015, Mercury and selenium contamination in waterbird eggs and risk to avian reproduction at Great Salt Lake, Utah: U.S. Geological Survey Open-File Report 2015-1020, 164 p., https://doi.org/10.3133/ofr20151020.
