The liver SGARs measured include Bromadiolone, Difenacoum, Brodifacoum, Difethialone, Flocoumafen and sum of SGARs in nanograms per gram-wet weight. The data also include demographic information (Age and Sex) for each bird and location where the bird was found.\n\nMembers of the public and other interested parties submitted Sparrowhawks to the Predatory Bird Monitoring Scheme (PBMS) after being found dead. The collection, examination, and archiving of birds and their tissues was conducted by the PBMS and supported by the Natural Environment Research Council award number NE/R016429/1 as part of the UK-SCAPE programme delivering National Capability. Contaminants and data analysis was conducted under the CHEMPOP project, NERC grant NE/S000100/1.
