The following data were used in the manuscript entitled "Migratory Connectivity of a Neotropical Migratory Songbird Revealed Using Archival Light-Level Geolocators" Hallworth et al. in press - Ecological Applications Manuscript # 14-0195 Questions regarding data should be directed to Mike Hallworth - mhallwor@masonlive.gmu.edu Names of data files and a brief description: Name -- Description bbsoven.txt -- Breeding Bird Survey data for Ovenbirds - raster format for R eBird_Data.xlsx -- eBird checklist data - see metadata within file EcolApps_Markdown.html -- an Rmarkdown file with sample code from the analyses in the text elevation_resampled.txt -- Elevation raster dataset resampled to 0.1x0.1 cell size ndvi.txt -- raster of change in NDVI scores from Nov-March nmix_predict.txt -- raster of the predicted Ovenbird abundance from N-mixture model - output from unmarked analysis OVEN_NonBreeding_Dist_WGS.shp -- Shapefile (and associated files) of Ovenbird non-breeding distribution in WGS84 projection (ie not projected) RoyleNichols_Abundance_covariates_NonSampled_removed.csv -- same file as eBird_Data without metadata and in .csv format unMarked_abundance_script.R -- Script used to determine non-breeding season abundance with R using the unmarked package Folders - Assignments_LambertProjection -- includes kernel density estimates of breeding and non-breeding locations and various shapefiles in Lambert Conic Conformal projection Breeding_KDE -- breeding kernel density estimates (WGS84) MigrationFiles -- Spring migration data from geolocators NonBreeding_Clipped_KDE -- Non-breeding kernel density estimates of Ovenbirds clipped to include locations over land (WGS84) *file names correspond to the last five digits of the individual's aluminium band.
