Ackerman, J.T., 2017, Mercury contamination in Anna’s hummingbirds: U.S. Geological Survey data release,


Heavy metal contamination (n=17 metals) of feather and tissue samples from live and deceased Anna's hummingbirds (Calypte anna) was evaluated. Feathers taken from live birds are low in sample weight, therefore a novel method was used in feather sample preparation. Feather samples were then analyzed utilizing an inductively coupled plasma mass spectrometry (ICP-MS) assay. In addition, ICP-MS was used to measure heavy metal concentrations in feather and tissue samples from salvaged hummingbird carcasses. Iron, zinc, selenium and mercury concentrations were most commonly elevated in body feathers from live birds with mercury being the metal most likely to be found in elevated concentrations. Because of this, we conducted additional analysis [...]
