    Abstract


    1. Determining global position by light measurements (‘geolocation’) has revolutionised the methods used to trackmigratory birds throughout their annual cycle.
    2. To date, there is no standard way of analysing geolocator data, making communication of analyses cumbersome and hampering the reproducibility of results.
    3. We have, therefore, developed the R package GeoLight, which provides basic functions for all steps of determining global positioning and a new approach in analysingmovement pattern.
    4. Here, we briefly introduce and discuss the major functions of this package using example movement data of European hoopoe (Upupa epops).
