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:
