Description
Summary:[Description of methods used for collection/generation of data] The dataset includes the raw data used to study the golden eagles´ diet in Burgos province. It includes data on prey remains collected below nests and at nearby plucking posts (mostly fresh remains, and some from pellets), although some prey remains (< 1%) were identified by direct observation of hunting eagles. Prey items were identified de visu , either directly, or by comparing the remains with a reference collection of feathers (i.e., for bird species) or with a reference collection of skull, bones and skin (i.e., for mammals). Some prey remains were not identified at the specific level, and were tabulated at Order level (e.g., Lagomorpha), at Phylum level (Reptilia), or even at a more general level (e.g., small mammals, including Rodentia and Insectivora). Prey remains were collected below nests and at nearby plucking posts (mostly fresh remains, and some from pellets), although we also accounted with some prey remains (< 1%) ... : [Methods for processing the data] For prey quantification at a site and sampling episode (one visit per pair and year) we estimated minimum number of prey individuals of each species. Data was tabulated in excel format comprising 1,916 records and 14 fields (columns), including information on pair identification, year of sampling, prey species and number, reproductive data for each monitored event and seven variables related with territory traits that have been found to have an influence on golden eagle’s productivity for the studied population (Fernández-Gil et al. 2023). ...
