We assessed total mercury concentrations in breast feathers of diurnal North American raptors collected at migration monitoring stations. We sampled raptor feathers from 9 species in the Pacific Flyway and compared species, sex, date, and flyway effects on mercury concentrations. We also explored year effects on 3 species of raptors in the Pacific Flyway during 13-years (2002-2014). Finally, we compared mercury concentrations in merlin among 4 continental flyways. These data support the following publication: Bourbour, R.P., Martinico, B.L., Ackerman, J.T., Herzog, M.P., Hull, A.C., Fish, A.M. and Hull, J.M., 2019. Feather mercury concentrations in North American raptors sampled at migration monitoring stations....

Wildfire events are becoming more frequent and severe on a global scale. Rising temperatures, prolonged drought, and the presence of pyrophytic invasive grasses are contributing to the degradation of native vegetation communities. Within the Great Basin region of the Western United States, increasing wildfire frequency is transforming the ecosystem toward a higher degree of homogeneity, one dominated by invasive annual grasses and declining landscape productivity. Greater sage-grouse (Centrocercus urophasianus; hereafter sage-grouse) are a species of conservation concern that rely on large tracts of structurally and functionally diverse sagebrush (Artemisia spp.) communities. Using a 12-year (2008-2019) telemetry...
