CURLEW_VLAANDEREN - Eurasian curlews (Numenius arquata, Scolopacidae) breeding in Flanders (Belgium) is a bird tracking dataset published by the Research Institute for Nature and Forest (INBO). It contains animal tracking data collected by the LifeWatch GPS tracking network for large birds (http://lifewatch.be/en/gps-tracking-network-large-birds) for the project/study CURLEW_VLAANDEREN, using trackers developed by Ornitela (https://www.ornitela.com). The study has been operational since 2020. In total 5 individuals of Eurasian curlew (Numenius arquata) have been tagged at several locations in Flanders (Belgium), mainly to study their habitat use and migration behaviour. Data are automatically synced with Movebank and from there periodically archived on Zenodo (see https://github.com/inbo/bird-tracking). Data in this package are exported from Movebank study CURLEW_VLAANDEREN - Eurasian curlews (Numenius arquata, Scolopacidae) breeding in Flanders (Belgium) (Movebank Study ID 1841091905), which can be viewed at https://www.movebank.org/cms/webapp?gwt_fragment=page=studies,path=study1841091905. Fields in the data follow the Movebank Attribute Dictionary (http://vocab.nerc.ac.uk/collection/MVB) and are described in datapackage.json. Files Files are structured as a Frictionless Data Package. You can access all data in R via https://zenodo.org/record/5779131/files/datapackage.json using frictionless. datapackage.json: technical description of the data files. CURLEW_VLAANDEREN-reference-data.csv: reference data about the animals, tags and deployments. CURLEW_VLAANDEREN-gps-yyyy.csv.gz: GPS data recorded by the tags, grouped by year. ; This dataset was collected using infrastructure provided by INBO and funded by Research Foundation - Flanders (FWO) as part of the Belgian contribution to LifeWatch. Additional funding was provided by Provincie Vlaams-Brabant. Data were collected in collaboration with Natuurpunt Studie.
