GPS tracking data and coded neckband reports for greylag geese breeding in Sweden (2017--2023)

This data set accompanies the following article published in Movement Ecology: van Toor, M.L., Fleming, C.H., Liljebäck, N. et al. Do GPS collars and coded neckbands tell the same story about year-round movements in geese?. Mov Ecol (2026). https://doi.org/10.1186/s40462-025-00620-y The data set contains the data used in the article, which together with the annotated R-code included in the article as supplementary material (available here) allows for the replication of the study results. The zip-file available for download contains the following three files: Reference data, with information on captured individuals File name: 250826_greylag_goose_metadata.csv File format: comma-separated values Included information: population: site of capture population.short: shorthand for the capture site as used in the article transmitter: logical; was the individual equipped with a GPS-transmitter? transmitter.id: numerical identifier for the deployed GPS-transmitter; NA if none neckband.code: 3-letter code of the neckband/GPS transmitter to be reported by observers steel.ringnumber: unique identifier of the steel tarsal band of that bird capture.date: date of first capture of the individual capture.lat: Latitude of the capture site, in decimal degrees capture.long: Longitude of the capture.site, in decimal degrees age: age of the individual at capture sex: sex of the individual bodymass: bodymass of the individual at capture, in grams Filtered and cleaned GPS tracking data File name: 250826_greylag_goose_gps_data.csv File format: comma-separated values Included information: population: site of capture population.short: shorthand for the capture site as used in the article transmitter: logical; was the individual equipped with a GPS-transmitter? transmitter.id: numerical identifier for the deployed GPS-transmitter; NA if none neckband.code: 3-letter code of the neckband/GPS transmitter to be reported by observers steel.ringnumber: unique identifier of the steel tarsal band of that bird timestamp: time and date of the acquisition of the GPS location (timezone: UTC, format: yyyy-mm-dd HH:MM:SS) location.lat: Latitude of the reported observation, in decimal degrees location.long: Longitude of the reported observation, in decimal degrees Filtered and cleaned neckband reports File name: 250826_greylag_goose_cmr_data.csv File format: comma-separated values Included information: population: site of capture population.short: shorthand for the capture site as used in the article transmitter: logical; was the individual equipped with a GPS-transmitter? transmitter.id: numerical identifier for the deployed GPS-transmitter; NA if none neckband.code: 3-letter code of the neckband/GPS transmitter to be reported by observers steel.ringnumber: unique identifier of the steel tarsal band of that bird date: date when the individual was observed, as reported location.lat: Latitude of the reported observation, in decimal degrees location.long: Longitude of the reported observation, in decimal degrees
