Journal: Ornithological applications Title -- Data from: Eastern Whip-poor-wills have larger non-breeding home ranges in areas with more agriculture and forest fragmentation Authors: Aaron A. Skinner, Stephen N. Matthews, Michael P. Ward, Ian Souza-Cole, James R. Wright, Frank R. Thompson III, Thomas J. Benson, Christopher M. Tonra Associated Manuscripts: Movement data used to calculate wintering home ranges available at Movebank Data Repository -- Data from: Study “GPS tracking of eastern whip-poor-will”. https://doi.org/10.5441/001/1.k6s7916g Abstract: We provide the data needed to recreate analyses predicting Eastern whip-poor-will non-breeding home range size and non-breeding stable isotope values. We deployed 94 GPS tags across a 9.5-degree latitudinal span (~1000 km) on whip-poor-wills in the summers of 2019. These tags collected data during the stationary non-breeding season, and we used satellite imagery to digitize associated landcover data at scales of the home range and site. The home range analysis .csv file contains 25 observations with whip-poor-will home range sizes (DV) and the associated predictor variables across three spatial scales (home range, site, and the geographic region). All variables are centered and scaled to facilitate comparisons of effect sizes. See methods in manuscript for more info. Column titles and short description: -uniq.ID: Unique tag ID -logHRS (DV): The log of the 2D home range size, calculated in the ctmm package Predictor variables at the scale of the home range: -edHR: Edge density, the amount of edge in relation to home range size -HRag: The proportion of agriculture in the home range -HRAgBin: A binary variable indicating whether a bird had agriculture in the home range or not -HRforest: The proportion of forest in the home range -HRscrub: The proportion of scrub in the home range -TRI: Terrain Ruggedness Index, calculated as the mean of the absolute value of the difference between the elevation (m) in the raster cell containing the centroid of an individual’s home range and the 8 surrounding cells -Wing: Unflattened wing chord Predictor variables at the scale of the site (500m buffer around the centroid of the home range): -Ag: The proportion of agriculture in the site -AgCat: A 3-level categorical variable indicating whether a bird had agriculture in the site -C13: The ratio of C13:C12 stable isotopes from whip-poor-will claws collected on the breeding grounds -Forest: The proportion of forest in the site -N15: The ratio of N15:N14 stable isotopes from whip-poor-will claws collected on the breeding grounds -pr: Patch richness, the number of unique patches present -Scrub: The proportion of scrub in the site -TE: The total amount of edge (the border between any two land cover types) in the site Predictor variables at the scale of the geographic region: -Dist.coast: distance to the nearest ocean coast -ecoR: One of three ecoregions (as defined by Ríos and Raga (2018)) where whip-poor-wills were present in the non-breeding region -W.Lat: Wintering latitude -W.Long: Wintering longitude
